[OMPI devel] Threshold for pinning down user-buffers

2014-05-23 Thread Siddhartha Jana 
Hi,
Is my understanding correct?
While servicing MPI_Send  using eager protocol over openib, there is a
data-size threshold below which it is preferred to copy the contents of the
user-buffer to a pre-pinned buffer instead of directly pinning down the
user-buffer. If this is correct, how does one determine this threshold?

As always, thanks for the help
Sid

[OMPI devel] Recommended tool to measure packet counters

2013-12-14 Thread Siddhartha Jana 
Is there a preferred method/tool among developers of MPI-library for
checking the count of the packets transmitted by the network card during
two-sided communication?

Is the use of
iptables -I INPUT -i eth0
iptables -I OUTPUT -o eth0

recommended ?

Thanks,
Siddhartha
