Subject: Re: [OMPI devel] Error in VT

Hi Leonardo,

I guess that your program uses POSIX threads and needs the MPI thread
support level MPI_THREAD_MULTIPLE, right?
Unfortunately, the OMPI integrated version of VT doesn't support neither
Pthreads nor any MPI thread level.

The latest "stand-alone-version" of VT (5.6.3) supports at least
Pthreads and the MPI thread support levels MPI_THREAD_SINGLE and
MPI_THREAD_FUNNELED. So if you can change the MPI thread level
requirement to MPI_THREAD_SINGLE or MPI_THREAD_FUNNELED tracing of your
code should work.
You can download the latest VT version at
http://www.tu-dresden.de/zih/vampirtrace. Please give it a try.

Regards,
Matthias Jurenz
