Subject: [OMPI users] Question on staging in checkpoint
From: ananda.mudar_at_[hidden]
Date: 2010-09-13 13:42:37



I was trying out the staging option in checkpoint where I save the
checkpoint image in local file system and have the image transferred to
global filesystem in the background. As part of the background process I
see that the "scp" command is launched to transfer the images from local
file system to global file system. I am using openmpi-1.5rc6 with BLCR


In my experiment, I had about 128 cores saved their respective
checkpoint images on local file system. During the background process, I
see that only 10 "scp" requests are sent at a time. Is this a
configurable parameter? Since these commands will run on respective
nodes, how can I launch all 128 scp requests (to take care of all 128
images in my experiment) simultaneously?
