Compiler detection errors on Cray #395
Comments
This appears to work correctly on Cori, although Cori has Intel 19 compilers. I wonder if the problem is related to Intel's changing of the version numbering scheme to full years (19.1 vs 2021.1) |
When using the OneAPI compilers, the Cray compilers use the LLVM-based compilers (icx and icpx). The MPI detection issue is resolved in #403. A new issue comes up during initialization, shown below. I believe this is related to this issue. I also confirmed that this error appears with gcc/g++ 10. Could we update the version of libunwind?

Sameer reports that on Narwhal at Navy DSRC (a Cray XC system) with Intel compilers 2021.1, MPI is not detected:
and the Fortran compiler is not detected correctly:
during
tau init --mpi --compiler-inst always
