Compiling CUDA code on HPC -- GPU Error at Runtime?

Hi all,

Thanks for all your work on k-Wave.
The pre-compiled CUDA binaries require GLIBC 2.27, which my HPC OS (CentOS Linux 7.2.1511) does not have. So I got the source codes and began compiling.

I am using HDF5 1.8.12, CUDA 10.0, gcc 7.2.0

The code compiles fine with the makefile. However, when running the code from MATLAB R2018b using kspaceFirstOrder3DG, it throws up the following error:

│GPU error: an illegal instruction was encountered routine │
│ name: cudaGetLastError() in file OutputStreams/ │
│ OutputStreamsCudaKernels.cu, line 130.

I'm wondering if you have any advice?

Best regards,

Daniel

Hi Daniel,
You compiled the code for a CPU instruction set the CPU you're running the code doesn't support. I guess you compiled the code on a different machine.

Change the CPU_ARCH to AVX. That should run everywhere.
```
CPU_ARCH = native
#CPU_ARCH = AVX
#CPU_ARCH = AVX2
#CPU_ARCH = AVX512
```
Best wishes
