Hi!

For me, perfmeter works fine, it has only a graphical interface but
this is enough for me. You can get it per ftp, but sorry, I do not
know more... it was already installed here.

Another way (I use most) is to write a little functions that messure
the time. There is a MPI-function returning the time called MPI_Wtime().
I use it in the following way:

int stime, etime = 0;

// loop ...
stime = MPI_Wtime();
.. MPI_Commands here ...
etime += MPI_Wtime() - stime;
// end of loop

// print etime...

Hope that helps,

	Benjamin.
