Finalizing MPI Collected Data

The finalization of the data (symbol resolution, conversion to the database) happens automatically after the collection has finished. It happens on the same compute node where the command line collection was executing, and so the binaries and symbol files will be located automatically by the amplxe-cl / inspxe-cl tools. In cases where the search process needs to be adjusted (common reason: need to point to symbol files stored elsewhere), the -search-dir option should be used with amplxe-cl / inspxe-cl as follows:

$ mpirun-np 128 amplxe-cl -q -collect hotspots -search-dir sym=/home/foo/syms ./a.out
