Thanks for reporting. I never seen such a behavior.
Does it work with other applications and multiple threads? Are you using some computing library like TBB, Cilk+, SYCL, ...? If it is OpenMP, is it one of the common implementations (GCC, LLVM, Intel)?
Describe the bug
likwid-pin appears to silently fail when using more than one thread, judging by the fact that the command exits almost immediately, and nothing is written to standard output.
To Reproduce
LIKWID command and/or API usage:
$ likwid-pin -V 2 -c 0,1 ./albm
LIKWID version and download source (Github, FTP, package manger, ...):
likwid-pin -- Version 5.3.0 (commit: 0123456789)
Operating system:
Linux maxwell 5.15.0-100-generic #110~20.04.1-Ubuntu SMP
Does your application use libraries like MPI, OpenMP or Pthreads? Yes, OpenMP.
Are you using the MarkerAPI (CPU code instrumentation)? No.
To Reproduce with a LIKWID command
Please supply the output of the command with
-V 3
added to the command:In contrast with a single thread I get:
If I run the application directly, it works as expected:
