[mpich-discuss] tracing mpi-io call

[Kaveri Zanje]

I want to study all adio calls for all file system ,
how this calls flow in IO stack like MPIIO -> ADIO , which calls are get
invoked in underlying libraries till local file system call.

actually I am interested in, How MPICH2 links all MPI-IO calls to underlying
file system's calls.
I thought call tracing will help me out to understand the call sequence made
by MPICH.

I have uses valgrind and c flow,
In valgrind i am not able to trace the call, how can i do this???
Is any other tool which can help me??
