[ptp-user] con't: Run PTP with more than one machine
|
Thanks for your time.
I did according to your guide,and I added a lot of nodes and I could see them in machine view(when I use "ping ..." command , it 's OK) . But I can't run my parallel application in these nodes ,there are not any results that are displayed although I ran that application well in one node(localhost) . Would you please show me how to run in many nodes( because I tried running, but node status of these nodes is yellow(this means : ALLOCATED TO YOU SHARED,BUT IDLE) ,not green (this means: job runing).I don't konw how to make it green (Job running).

You are correct. The text on this picture is misleading. The icons in the "machines view" represent the nodes of a
parallel machine. So PTP 1.1 supports one parallel machine that has many nodes. Information about the nodes is provided by the OpenMPI runtime, so you need to modify the OpenMPI configuration to see more than one node. For example, if you have a number of systems you'd like to use as an ad-hoc cluster, you would edit /usr/local/etc/openmpi-default-hostfile and add the hostname of each of your systems. When you restart Eclipse, you should now see these hosts appear as "nodes" in your parallel machine.

Can you explain that when I read "The PTP User Guide" on site
http://www.eclipse.org/ptp/ ,there are many nodes
on Tab machine (from 0 to 256) ,so where do these machines come from?
And how can I add them to my parallel application?
Unfortunately this is not supported in PTP 1.1. We are adding this functionality to the next version of PTP, 2.0, which will be available later this year.
