Hi, I am working on a project that requires a global synchronous time 
on all nodes running MPI. I understand that MPI_Wtime only returns
a local time and "no requirement that different nodes return the
same time"(from MPI spec) Has anyone encountered the same problem?
Any suggestions to obtain such a global time in MPI?


Thanks in advanced,
