#2861: Running qc0 with CarpetX
Reporter:Alejandra Gonzalez
Status:submitted
Milestone:

Type:bug
Priority:major
Component:EinsteinToolkit thorn

I’m currently testing CarpetX in the new MareNostrum 5 and attempted to run the parfiles here:
https://github.com/EinsteinToolkit/SpacetimeX/tree/main/Punctures/par
specifically qc0 and qc0-unigrid.
However I get the following error right at initialization (for both):
