Output

By default HPMCOUNT writes to stdout, which can be changed with the -o option of HPMCOUNT. For a parallel job writing to stdout, we recommend setting MP_STDOUTMODE=ordered to prevent the processors from writing interleaved. This has to be set in the LoadLeveler script. The following example is for ksh:

  export MP_STDOUTMODE=ordered

When using the -o option, each processor writes its own output and setting MP_STDOUTMODE=ordered is not required.
