I have to consume resources just for testing. So I was curious if you
know a tool/procedure that works much faster. Of course filling the

the clusters are 64 bit.
I execute the benchmark with the following command:

Dear all,
I would like you to ask for a topic that there are already many
questions but I am not familiar a lot with it. I want to understand the
behaviour of an application where there are many messages less than 64KB
(eager mode) and I use TCP network. I am trying to understand in order

ever I was expecting that with disabled the eager mode the duration
of MPI_Send should be longer. Am I wrong? Is there any option for making
the MPI_Send to behave like blocking command for all the sizes of the
messages?
Thanks a lot,

You can add the following MCA parameters either on the command line or
in the $(HOME)/.openmpi/mca-params.conf file.

Dear all,
I would like to ask about collective communication. With debug mode

used etc. But my question is that I would like to use a specific
algorithm (the simplest I suppose). I am profiling some applications and
