Carpet Vs. CarpetX

Currently there are two production drivers in the Einstein Toolkit: Carpet and CarpetX.

Carpet is a CPU based Adaptive Mesh Refinement (AMR) framework that has been a part of the Einstein Toolkit since 2006. It has seen extensive production use and should work out of the box when you get an official release of the Einstein Toolkit. If you are using Carpet, please see the official download and install instructions here.

CarpetX is a new AMR driver capable of running on CPUs and GPUs. It is ready for production use and is also a part of the Einstein Toolkit. However, when using CarpetX, a number of thorns that are required for fully featured numerical relativity simulations are not included in the official release. This requires a different thornlist(s) depending on which features are desired. This is because either thorns are still in development phase or some existing Carpet thorns are not compatible with CarpetX (yet).

For this reason, we are presenting a collection of thornlists for checking out various components required for fully featured simulations. This is a temporary solution and, in the future, such thornlists are expected to be no longer necessary once CarpetX thorns are included in the official release.

Basic CarpetX, no subcycling in time

This thornlist provides a basic cactus checkout, with CarpetX, and its required external libraries. It also includes:

1. Spacetime evolution codes (CanudaX, Cottonmouth, Z4c)
2. Spacetime evolution utilities (Initial data, puncture tracking, apparent horizon finding)
3. GRMHD evolution code AsterX
