Hi Patrick,
Thanks for your reply.
Ofcourse, the intel vars.sh is sourced inside the pbs script and I've tried
multiple ways to resolve this issue:
-x LD_LIBRARY_PATH
&
-x
LD_LIBRARY_PATH=/opt/intel/oneapi/2024/v2.1/compiler/2024.2/opt/compiler/lib:/opt/intel/oneapi/2024/v2.1/compiler/2024.2/lib:${LD_LIBRARY_PATH}
And then copied the libimf.so to job's working directory and set
-x
LD_LIBRARY_PATH=.:/opt/intel/oneapi/2024/v2.1/compiler/2024.2/opt/compiler/lib:/opt/intel/oneapi/2024/v2.1/compiler/2024.2/lib:${LD_LIBRARY_PATH}
But in any of the case it didn't work
