Test case segfaults - v9.1.0

[saisandeepdammati]

Howdy!

I am using the latest commit from the superlu_dist repo and trying to compile the code using cmake on a Cray machine. Attached is the compilation log. As you can see the compilation goes through successfully and generates the necessary include and library files in /p/home/sdammati/local/. However, if I go to /p/home/sdammati/local/lib64/EXAMPLE directory where it generates the example executable files and try one of the executable file pddrive on big.rua matrix, the run segfaults even in serial. I also tried running it in parallel on multiple cores and the result is the same.

I am using Cray MPICH version 8.1.30 for compilation.

Can you please help me figure out what is the issue? Is there any specific compiler that I need to use to compile superlu_dist on Cray machines?

Hi, I just gave it a try of https://github.com/xiaoyeli/superlu_dist/blob/master/example_scripts/run_cmake_build_perlmutter_oneAPI.sh
and pddrive gives no errors. I looked at your build output but didn't notice any anomaly. But since you have a core dump, could you use gdb to ping which line is causing segfault?

Also, have you tried PrgEnv-gnu if your system has one?

Thanks for your response. I will give it a try using GNU compilers. However, I compiled v9.0.0 successfully with Cray compiler and was able to run the example problems pddrive and pddrive3D1 without any issues.
