=== Einstein Toolkit for VirtualBox ===
[[Image:ETK2015 Snapshot.jpeg|thumb|right|200px|Snapshot of the ETK OS]]

For the Einstein Toolkit tutorial, we have prepared a [https://www.virtualbox.org/ VirtualBox] disk with a Debian Linux-based ETK-OS, which contains all the necessary ingredients to start using Einstein Toolkit: the [http://cactuscode.org Cactus code], [http://carpetcode.org Carpet] parallel adaptive mesh refinement driver for the Cactus, [http://simfactory.org SimFactory] for managing simulations, [http://www.gnuplot.info gnuplot], [http://cactuscode.org/documentation/visualization/yGraph/ ygraph] and [https://wci.llnl.gov/simulation/computer-codes/visit VisIt] for 1D and 3D visualizations.

The virtual machine can be downloaded at the following links:

* [http://compact-merger.astro.su.se/ETK2015/ETK-2015.vdi.zip ETK-2015.vdi.zip] ('''3.4 GB --> 9.2 GB''' when inflated)
* [http://compact-merger.astro.su.se/ETK2015/ETK-2015.vdi.zip.md5 ETK-2015.vdi.zip.md5] (MD5 checksum for the zip archive)
* [http://compact-merger.astro.su.se/ETK2015/ETK-2015.vdi.pxz ETK-2015.vdi.pxz] ('''2.3 GB''' - .xz archive)
* [http://compact-merger.astro.su.se/ETK2015/ETK-2015.vdi.pxz.md5 ETK-2015.vdi.pxz.md5] (MD5 checksum for the .xz archive)
* [http://compact-merger.astro.su.se/ETK2015/ETK-2015.vdi.gz ETK-2015.vdi.gz] ('''3.4 GB''' - .gz archive)
* [http://compact-merger.astro.su.se/ETK2015/ETK-2015.vdi.gz.md5 ETK-2015.vdi.gz.md5] (MD5 checksum for the .gz archive)

If your computer has AFS client installed, you might find it more convenient to copy the archive from AFS partition:

/afs/astro.su.se/service/www/compact-merger.astro.su.se/ETK2015/ETK-2015.vdi.zip
/afs/astro.su.se/service/www/compact-merger.astro.su.se/ETK2015/ETK-2015.vdi.zip.md5

==== Configuring VirtualBox (Linux version) ====
[[Image:VirtualBox_ETK2015_Snapshot.jpeg|thumb|left|200px|VirtualBox settings]]

If you want to test Einstein Toolkit in virtual environment, follow these steps.

# Download and install [https://www.virtualbox.org/ Oracle VirtualBox] on your laptop.
# Run it: Oracle VM VirtualBox Manager appears. Select "New" to create a new virtual machine.
# Give a name, e.g: EinsteinToolkit
# Select ''Type: Linux'', ''Version: Debian (32-bit)''
# Select generous amount of RAM for your virtual machine (>1GB)
# Pick an option ''Use an existing virtual hard drive'' and point it to the unzipped file: '''ETK-2015.vdi'''. Press OK (or Create) to create the VM.
# Select ''Settings'' > ''Display'' and allocate at least 32MB for your virtual display (Video memory).
# Select ''Settings'' > ''Processor'' (might be under "System") and click the checkbox to enable PAE/NX.
# If your laptop has more than one core which you would like to use in virtual machine also, but it's greyed out, you might need to enable hardware virtualization support (e.g. VT-x for Intel processors) in your BIOS
# Choose the number of cores that you want to use in "Processor"
# Start your VM; use '''etk''' both for the username and password in Linux.

==== Running a test simulation ====

On the virtual machine, ETK comes preconfigured with the default configuration '''sim''' (for a brief introduction into Cactus framework and terminology, see [[Tutorial for New Users]]). Precompiled executable is:

./Cactus/exe/cactus_sim

You could start a test simulation either directly,

mkdir ~/simulations/test
cd ~/Cactus
cp exe/cactus_sim par/static_tov.par ~/simulations/test
cd ~/simulations/test
./cactus_sim static_tov.par

or using SimFactory:

cd ~/Cactus
simfactory/bin/sim submit test --parfile=par/static_tov.par

These test simulations create and evolve a static relativistic TOV star in full GR, in an octant with 5 levels of refinement. Current VM already contains a test simulation, located at:

cd ~/simulations/static-tov/output-0000

Please refer to the [[Tutorial for New Users]] for more details about configuring, compiling, running Cactus, and using SimFactory to simplify these tasks. In SimFactory, the machine configuration file for the ETK OS is ''simfactory/mdb/machines/etk.etk.ini'', the optionlist is ''etk.cfg'' and the runscript is ''generic.run''. If you succeeded with virtualizing multiple cores in your VM, you could try the ''generic-mpi.run'' runscript for running on multiple cores and/or with multiple OpenMP threads.

==== Older versions of ETK OS VMs ====

Current version of the ETK OS contains the latest (by 2015) release of the Einstein Toolkit ("Hilbert") and runs on 32-bit Debian Linux with i686-pae architecture (which allows hardware virtualization). Previous versions used i486 architecture. You can find the original versions [https://www.cct.lsu.edu/~dcastl2/data-storage/virtual-machines/etk here] (created by Dennis Castleberry).

=== Einstein Toolkit for VirtualBox ===
[[Image:ETK2015 Snapshot.jpeg|thumb|right|200px|Snapshot of the ETK OS]]

For the Einstein Toolkit tutorial, we have prepared a [https://www.virtualbox.org/ VirtualBox] disk with a Debian Linux-based ETK-OS, which contains all the necessary ingredients to start using Einstein Toolkit: the [http://cactuscode.org Cactus code], [http://carpetcode.org Carpet] parallel adaptive mesh refinement driver for the Cactus, [http://simfactory.org SimFactory] for managing simulations, [http://www.gnuplot.info gnuplot], [http://cactuscode.org/documentation/visualization/yGraph/ ygraph] and [https://wci.llnl.gov/simulation/computer-codes/visit VisIt] for 1D and 3D visualizations.

The virtual machine can be downloaded at the following links:

* [http://compact-merger.astro.su.se/ETK2015/ETK-2015.vdi.zip ETK-2015.vdi.zip] ('''3.4 GB --> 9.2 GB''' when inflated)
* [http://compact-merger.astro.su.se/ETK2015/ETK-2015.vdi.zip.md5 ETK-2015.vdi.zip.md5] (MD5 checksum for the zip archive)
* [http://compact-merger.astro.su.se/ETK2015/ETK-2015.vdi.pxz ETK-2015.vdi.pxz] ('''2.3 GB''' - .xz archive)
* [http://compact-merger.astro.su.se/ETK2015/ETK-2015.vdi.pxz.md5 ETK-2015.vdi.pxz.md5] (MD5 checksum for the .xz archive)
* [http://compact-merger.astro.su.se/ETK2015/ETK-2015.vdi.gz ETK-2015.vdi.gz] ('''3.4 GB''' - .gz archive)
* [http://compact-merger.astro.su.se/ETK2015/ETK-2015.vdi.gz.md5 ETK-2015.vdi.gz.md5] (MD5 checksum for the .gz archive)

If your computer has AFS client installed, you might find it more convenient to copy the archive from AFS partition:

/afs/astro.su.se/service/www/compact-merger.astro.su.se/ETK2015/ETK-2015.vdi.zip
/afs/astro.su.se/service/www/compact-merger.astro.su.se/ETK2015/ETK-2015.vdi.zip.md5

/afs/astro.su.se/service/www/compact-merger.astro.su.se/ETK2015/ETK-2015.vdi.gz.md5

==== Configuring VirtualBox (Linux version) ====
[[Image:VirtualBox_ETK2015_Snapshot.jpeg|thumb|left|200px|VirtualBox settings]]

If you want to test Einstein Toolkit in virtual environment, follow these steps.

# Download and install [https://www.virtualbox.org/ Oracle VirtualBox] on your laptop.
# Run it: Oracle VM VirtualBox Manager appears. Select "New" to create a new virtual machine.
# Give a name, e.g: EinsteinToolkit
# Select ''Type: Linux'', ''Version: Debian (32-bit)''
# Select generous amount of RAM for your virtual machine (>1GB)
# Pick an option ''Use an existing virtual hard drive'' and point it to the unzipped file: '''ETK-2015.vdi'''. Press OK (or Create) to create the VM.
# Select ''Settings'' > ''Display'' and allocate at least 32MB for your virtual display (Video memory).
# Select ''Settings'' > ''Processor'' (might be under "System") and click the checkbox to enable PAE/NX.
# If your laptop has more than one core which you would like to use in virtual machine also, but it's greyed out, you might need to enable hardware virtualization support (e.g. VT-x for Intel processors) in your BIOS
# Choose the number of cores that you want to use in "Processor"
# Start your VM; use '''etk''' both for the username and password in Linux.

==== Running a test simulation ====

On the virtual machine, ETK comes preconfigured with the default configuration '''sim''' (for a brief introduction into Cactus framework and terminology, see [[Tutorial for New Users]]). Precompiled executable is:

./Cactus/exe/cactus_sim

You could start a test simulation either directly,

mkdir ~/simulations/test
cd ~/Cactus
cp exe/cactus_sim par/static_tov.par ~/simulations/test
cd ~/simulations/test
./cactus_sim static_tov.par

or using SimFactory:

cd ~/Cactus
simfactory/bin/sim submit test --parfile=par/static_tov.par

These test simulations create and evolve a static relativistic TOV star in full GR, in an octant with 5 levels of refinement. Current VM already contains a test simulation, located at:

cd ~/simulations/static-tov/output-0000

Please refer to the [[Tutorial for New Users]] for more details about configuring, compiling, running Cactus, and using SimFactory to simplify these tasks. In SimFactory, the machine configuration file for the ETK OS is ''simfactory/mdb/machines/etk.etk.ini'', the optionlist is ''etk.cfg'' and the runscript is ''generic.run''. If you succeeded with virtualizing multiple cores in your VM, you could try the ''generic-mpi.run'' runscript for running on multiple cores and/or with multiple OpenMP threads.

==== Older versions of ETK OS VMs ====

Current version of the ETK OS contains the latest (by 2015) release of the Einstein Toolkit ("Hilbert") and runs on 32-bit Debian Linux with i686-pae architecture (which allows hardware virtualization). Previous versions used i486 architecture. You can find the original versions [https://www.cct.lsu.edu/~dcastl2/data-storage/virtual-machines/etk here] (created by Dennis Castleberry).

=== Einstein Toolkit for VirtualBox ===
[[Image:ETK2015 Snapshot.jpeg|thumb|right|200px|Snapshot of the ETK OS]]

For the Einstein Toolkit tutorial, we have prepared a [https://www.virtualbox.org/ VirtualBox] disk with a Debian Linux-based ETK-OS, which contains all the necessary ingredients to start using Einstein Toolkit: the [http://cactuscode.org Cactus code], [http://carpetcode.org Carpet] parallel adaptive mesh refinement driver for the Cactus, [http://simfactory.org SimFactory] for managing simulations, [http://www.gnuplot.info gnuplot], [http://cactuscode.org/documentation/visualization/yGraph/ ygraph] and [https://wci.llnl.gov/simulation/computer-codes/visit VisIt] for 1D and 3D visualizations.

The virtual machine can be downloaded at the following links:

* [http://compact-merger.astro.su.se/ETK2015/ETK-2015.vdi.zip ETK-2015.vdi.zip] ('''3.4 GB --> 9.2 GB''' when inflated)
* [http://compact-merger.astro.su.se/ETK2015/ETK-2015.vdi.zip.md5 ETK-2015.vdi.zip.md5] (MD5 checksum for the zip archive)
* [http://compact-merger.astro.su.se/ETK2015/ETK-2015.vdi.pxz ETK-2015.vdi.pxz] ('''2.3 GB''' - .xz archive)
* [http://compact-merger.astro.su.se/ETK2015/ETK-2015.vdi.pxz.md5 ETK-2015.vdi.pxz.md5] (MD5 checksum for the .xz archive)
* [http://compact-merger.astro.su.se/ETK2015/ETK-2015.vdi.gz ETK-2015.vdi.gz] ('''3.4 GB''' - .gz archive)
* [http://compact-merger.astro.su.se/ETK2015/ETK-2015.vdi.gz.md5 ETK-2015.vdi.gz.md5] (MD5 checksum for the .gz archive)

If your computer has AFS client installed, you might find it more convenient to copy the archive from AFS partition:

/afs/astro.su.se/service/www/compact-merger.astro.su.se/ETK2015/ETK-2015.vdi.zip
/afs/astro.su.se/service/www/compact-merger.astro.su.se/ETK2015/ETK-2015.vdi.zip.md5

/afs/astro.su.se/service/www/compact-merger.astro.su.se/ETK2015/ETK-2015.vdi.gz.md5

==== Configuring VirtualBox (Linux version) ====
[[Image:VirtualBox_ETK2015_Snapshot.jpeg|thumb|left|200px|VirtualBox settings]]

If you want to test Einstein Toolkit in virtual environment, follow these steps.

# Download and install [https://www.virtualbox.org/ Oracle VirtualBox] on your laptop.
# Run it: Oracle VM VirtualBox Manager appears. Select "New" to create a new virtual machine.
# Give a name, e.g: EinsteinToolkit
# Select ''Type: Linux'', ''Version: Debian (32-bit)''
# Select generous amount of RAM for your virtual machine (>1GB)
# Pick an option ''Use an existing virtual hard drive'' and point it to the unzipped file: '''ETK-2015.vdi'''. Press OK (or Create) to create the VM.
# Select ''Settings'' > ''Display'' and allocate at least 32MB for your virtual display (Video memory).
# Select ''Settings'' > ''Processor'' (might be under "System") and click the checkbox to enable PAE/NX.
# If your laptop has more than one core which you would like to use in virtual machine also, but it's greyed out, you might need to enable hardware virtualization support (e.g. VT-x for Intel processors) in your BIOS
# Choose the number of cores that you want to use in "Processor"
# Start your VM; use '''etk''' both for the username and password in Linux.

==== Running a test simulation ====

On the virtual machine, ETK comes preconfigured with the default configuration '''sim''' (for a brief introduction into Cactus framework and terminology, see [[Tutorial for New Users]]). Precompiled executable is:

./Cactus/exe/cactus_sim

You could start a test simulation either directly,

mkdir ~/simulations/test
cd ~/Cactus
cp exe/cactus_sim par/static_tov.par ~/simulations/test
cd ~/simulations/test
./cactus_sim static_tov.par

or using SimFactory:

cd ~/Cactus
simfactory/bin/sim submit test --parfile=par/static_tov.par

These test simulations create and evolve a static relativistic TOV star in full GR, in an octant with 5 levels of refinement. Current VM already contains a test simulation, located at:

cd ~/simulations/static-tov/output-0000

Please refer to the [[Tutorial for New Users]] for more details about configuring, compiling, running Cactus, and using SimFactory to simplify these tasks. In SimFactory, the machine configuration file for the ETK OS is ''simfactory/mdb/machines/etk.etk.ini'', the optionlist is ''etk.cfg'' and the runscript is ''generic.run''. If you succeeded with virtualizing multiple cores in your VM, you could try the ''generic-mpi.run'' runscript for running on multiple cores and/or with multiple OpenMP threads.

==== Older versions of ETK OS VMs ====

Current version of the ETK OS contains the latest (by 2015) release of the Einstein Toolkit ("Hilbert") and runs on 32-bit Debian Linux with i686-pae architecture (which allows hardware virtualization). Previous versions used i486 architecture. You can find the original versions [https://www.cct.lsu.edu/~dcastl2/data-storage/virtual-machines/etk here] (created by Dennis Castleberry).

=== Einstein Toolkit for VirtualBox ===
[[Image:ETK2015 Snapshot.jpeg|thumb|right|200px|Snapshot of the ETK OS]]

For the Einstein Toolkit tutorial, we have prepared a [https://www.virtualbox.org/ VirtualBox] disk with a Debian Linux-based ETK-OS, which contains all the necessary ingredients to start using Einstein Toolkit: the [http://cactuscode.org Cactus code], [http://carpetcode.org Carpet] parallel adaptive mesh refinement driver for the Cactus, [http://simfactory.org SimFactory] for managing simulations, [http://www.gnuplot.info gnuplot], [http://cactuscode.org/documentation/visualization/yGraph/ ygraph] and [https://wci.llnl.gov/simulation/computer-codes/visit VisIt] for 1D and 3D visualizations.

The virtual machine can be downloaded at the following links:

* [http://compact-merger.astro.su.se/ETK2015/ETK-2015.vdi.zip ETK-2015.vdi.zip] ('''3.4 GB --> 9.2 GB''' when inflated)
* [http://compact-merger.astro.su.se/ETK2015/ETK-2015.vdi.zip.md5 ETK-2015.vdi.zip.md5] (MD5 checksum for the zip archive)

=== Einstein Toolkit for VirtualBox ===
[[Image:ETK2015 Snapshot.jpeg|thumb|right|200px|Snapshot of the ETK OS]]

For the Einstein Toolkit tutorial, we have prepared a [https://www.virtualbox.org/ VirtualBox] disk with a Debian Linux-based ETK-OS, which contains all the necessary ingredients to start using Einstein Toolkit: the [http://cactuscode.org Cactus code], [http://carpetcode.org Carpet] parallel adaptive mesh refinement driver for the Cactus, [http://simfactory.org SimFactory] for managing simulations, [http://www.gnuplot.info gnuplot], [http://cactuscode.org/documentation/visualization/yGraph/ ygraph] and [https://wci.llnl.gov/simulation/computer-codes/visit VisIt] for 1D and 3D visualizations.

The virtual machine can be downloaded at the following links:

* [http://compact-merger.astro.su.se/ETK2015/ETK-2015.vdi.zip ETK-2015.vdi.zip] ('''3.4 GB --> 9.2 GB''' when inflated)
* [http://compact-merger.astro.su.se/ETK2015/ETK-2015.vdi.zip.md5 ETK-2015.vdi.zip.md5] (MD5 checksum for the zip archive)
* [http://compact-merger.astro.su.se/ETK2015/ETK-2015.vdi.pxz ETK-2015.vdi.pxz] ('''2.3 GB''' - .xz archive)
* [http://compact-merger.astro.su.se/ETK2015/ETK-2015.vdi.pxz.md5 ETK-2015.vdi.pxz.md5] (MD5 checksum for the .xz archive)
* [http://compact-merger.astro.su.se/ETK2015/ETK-2015.vdi.gz ETK-2015.vdi.gz] (''' --> 9.2 GB''' when inflated)

If your computer has AFS client installed, you might find it more convenient to copy the archive from AFS partition:

/afs/astro.su.se/service/www/compact-merger.astro.su.se/ETK2015/ETK-2015.vdi.zip
/afs/astro.su.se/service/www/compact-merger.astro.su.se/ETK2015/ETK-2015.vdi.zip.md5

/afs/astro.su.se/service/www/compact-merger.astro.su.se/ETK2015/ETK-2015.vdi.pxz.md5

==== Configuring VirtualBox (Linux version) ====
[[Image:VirtualBox_ETK2015_Snapshot.jpeg|thumb|left|200px|VirtualBox settings]]

If you want to test Einstein Toolkit in virtual environment, follow these steps.

# Download and install [https://www.virtualbox.org/ Oracle VirtualBox] on your laptop.
# Run it: Oracle VM VirtualBox Manager appears. Select "New" to create a new virtual machine.
# Give a name, e.g: EinsteinToolkit
# Select ''Type: Linux'', ''Version: Debian (32-bit)''
# Select generous amount of RAM for your virtual machine (>1GB)
# Pick an option ''Use an existing virtual hard drive'' and point it to the unzipped file: '''ETK-2015.vdi'''. Press OK (or Create) to create the VM.
# Select ''Settings'' > ''Display'' and allocate at least 32MB for your virtual display (Video memory).
# Select ''Settings'' > ''Processor'' (might be under "System") and click the checkbox to enable PAE/NX.
# If your laptop has more than one core which you would like to use in virtual machine also, but it's greyed out, you might need to enable hardware virtualization support (e.g. VT-x for Intel processors) in your BIOS
# Choose the number of cores that you want to use in "Processor"
# Start your VM; use '''etk''' both for the username and password in Linux.

==== Running a test simulation ====

On the virtual machine, ETK comes preconfigured with the default configuration '''sim''' (for a brief introduction into Cactus framework and terminology, see [[Tutorial for New Users]]). Precompiled executable is:

./Cactus/exe/cactus_sim

You could start a test simulation either directly,

mkdir ~/simulations/test
cd ~/Cactus
cp exe/cactus_sim par/static_tov.par ~/simulations/test
cd ~/simulations/test
./cactus_sim static_tov.par

or using SimFactory:

cd ~/Cactus
simfactory/bin/sim submit test --parfile=par/static_tov.par

These test simulations create and evolve a static relativistic TOV star in full GR, in an octant with 5 levels of refinement. Current VM already contains a test simulation, located at:

cd ~/simulations/static-tov/output-0000

Please refer to the [[Tutorial for New Users]] for more details about configuring, compiling, running Cactus, and using SimFactory to simplify these tasks. In SimFactory, the machine configuration file for the ETK OS is ''simfactory/mdb/machines/etk.etk.ini'', the optionlist is ''etk.cfg'' and the runscript is ''generic.run''. If you succeeded with virtualizing multiple cores in your VM, you could try the ''generic-mpi.run'' runscript for running on multiple cores and/or with multiple OpenMP threads.

==== Older versions of ETK OS VMs ====

Current version of the ETK OS contains the latest (by 2015) release of the Einstein Toolkit ("Hilbert") and runs on 32-bit Debian Linux with i686-pae architecture (which allows hardware virtualization). Previous versions used i486 architecture. You can find the original versions [https://www.cct.lsu.edu/~dcastl2/data-storage/virtual-machines/etk here] (created by Dennis Castleberry).

In SimFactory, the machine configuration file for the ETK OS is ''simfactory/mdb/machines/etk.etk.ini'', the optionlist is ''etk.cfg'' and the runscript is ''generic.run''. If you succeeded with virtualizing multiple cores in your VM, you could try the ''generic-mpi.run'' runscript for running on multiple cores and/or with multiple OpenMP threads.
