Hi all,
I would like to know whether it is currently possible to run the Einstein Toolkit in a GPU-only cluster, since my group is planning to apply for a cluster like this. In particular, I would like to know if I would be able to run a BBH simulation like the example in the gallery.
I know there was this question in http://lists.einsteintoolkit.org/pipermail/users/2020-July/007508.html some time ago, focused on the development of CarpetX, but I'm not sure what's the current status or if this means that simulations using Carpet wouldn't run on a GPU.
Thanks in advance! Santiago

As you mention, CarpetX supports GPUs, and there is a GPU version of Z4c for binary black holes. However, various analysis methods either have not yet been tested on GPUs or do not yet support GPUs. Running the gallery example on a GPU is probably not yet possible, although we should be close.

Okay, thanks for the answer!
