Intel trace analyzer for MPI code (Linux)

SashaRoss — Thu, 21 Dec 2023 16:24:51 GMT

Hi,

I'm trying to get some profiling of the code written in fortran and compiled with ifort. I've installed Intel oneapi HPC toolkit, sourced setvars.sh. I've added "-trace" flag to my Makefile so that I am able to "make" it and then "mpirun -n 8 <filename>" runs it. The only file I see, however, is <filename>.prot, which looks like a binary file so I have no idea what to do with and how to get <something>.stf for further analysis with traceanalyzer tool. Could someone please help me here?

Another problem arises if instead of "mpirun -n 8 ..." I'm using "mpirun -trace -n 8 ....": the simulation initializes the grid and then terminates with the following error:

[0] Intel(R) Trace Collector ERROR: Unexpected empty communicator [_sdks/release_posix-x86_64_icl_2021.9_gnut

I have no idea whatsoever as to why it lists icl compiler (for Windows?!) and what can be done here.

Any help will be appreciated.
