Thanks,

From  http://valgrind.org/docs/manual/mc-manual.html#mc-manual.mpiwrap

I find that 

"Currently the wrappers are only buildable with mpiccs which are based on GNU GCC or Intel's C++ Compiler."

The cluster which I am working on is using GNU Open MPI mpic++. i am afraid that the Valgrind wrapper can work here. 

I do not have system administrator authorization. 

Are there other mem-checkers (open source) that can do this ?

thanks

Jack

Could you try to build openMPI without memory management (using --without-memory-manager) and let us know the outcome. ptmalloc is not needed if you are not using an RDMA interconnect.
