got KeyError: "'mul' has no providers" with openmp backend

[Jing]

Hi,

We tested the sd7003 benchmark on two very similar Cray XC systems with openmp backend but the test on one system failed with error likes

...

KeyError: "'mul' has no providers"
Rank 0 [Wed Mar 11 23:44:42 2020]  application called MPI_Abort(MPI_COMM_WORLD, 1) - process 0

...

From one old discussion, the error seems to be related to the "cblas" setting in the .ini file. We used the Intel MKL library on both system and the setting likes

...

backend-openmp]
cc=gcc
cblas = <intel_installation_path>/mkl/lib/intel64/libmkl_intel_lp64.so
...

but one system work and the other does not.

What is the error? Is the error related to PyFR installation or the setting in the input file?

Thanks a lot for your help.

Regards, Jing
