HPL run fails (libmkl_intel_lp64.so: cannot open shared object file)

Accelerated Computing CUDA CUDA Setup and Installation
1

Hi,

I’m trying to run HPL compiled using CUDA.

What I have on the system:

  1. Nvidia driver (TESLA DRIVER FOR LINUX RHEL 7, Version: 390.30)
  2. CUDA installation toolkit (cuda-repo-rhel7-9-1-local-9.1.85-1.x86_64.rpm)
  3. Mpich (mpich-3.2.1)
  4. openBLAS (OpenBLAS-0.2.20)
  5. HPL provided by nvidia (hpl-2.0_FERMI_v15_latest)

When I run the code it complaints about missing libmkl_intel_lp64.so but when i do ldd for xhpl, it shows no dependency on libmkl_intel_lp64.so. Moreover i’ve used openblas to compile HPL not sure why is it asking for an intel make library!

Any suggestions.

What I run:
/root/hpl/mpich/bin/mpirun -np 1 -hostfile nodes ./run_linpack

Error:
libmkl_intel_lp64.so: cannot open shared object file: No such file or directory

*Can’t see libmkl_intel_lp64.so mentioned anywhere there but still everytime i run HPL it complaints about missing libmkl_intel_lp64.so

Thanks,

MKL is related to the Intel Math Kernel Library. Couldn’t comment on how that’s getting pulled in.
