Question about Eigen and GPUSPH spheric 2022

1

Dear GPUSPH development team
When I try to run GPUSPH(spheric 2022), the test cases about FEA can not work. But the other cases can work very well.

The operating system: Ubuntu 20.04
GPU card: Tesla A100
Eigen 3.4.0
Could you give me some suggestions on solving the problem? It would be a great help and I would really appreciate it. Thank you very much and I am looking forward to hearing from you.
Best regards.

Hello @ColarJohn, can you try adding

CXXFLAGS += -march=native

to your Makefile.local? (create the file if it does not exist)

Do a make clean afterwards, to make sure all of GPUSPH is rebuilt with the new flag.
