According to the VampirTrace documentation, it is possible to create a symbol list file in advance and set the name of the file in the environment variable VT_GNU_NMFILE. For example, you might do this:
$ nm hello > hello.nm $ export VT_GNU_NMFILE="hello.nm" I have set up a symbol file list as above (with full path name of course) but when I run my VT instrumented program (via mpirun) it appears to ignore the VT_GNU_NMFILE environment variable and run "nm" automatically on startup (the default behavior). This can be a time consuming process, so I would prefer to use the pre-created symbol list file. Can anyone confirm if the VT_GNU_NMFILE environment variable is supported with the OpenMPI integration? Thanks, Rocky
