Re: [ptp-announce] PTP Compiling causes other nodes on cluster to be unavailable

Hi Mark,

In the future, please use the ptp-dev or ptp-user list for this type of question. ptp-announce is for announcements about PTP only.

Hi All,



I have spent some time with PTP over the last 3 weeks as looking to use it as a framework for some research work.



By following the install process using CDT and PTP I got everything up and running except that in PTP Runtime it only shows me the node on which I run eclipse and only allows me to run my processes on this node. I am working on an 8 node linux x86_64 cluster.



The problem is that after the install process I can’t run my openMPI 1.2.4 test program in a bash shell using any other nodes, only the node I am on. For eg: mpirun –np 8 –host currentNode,othernode1,othernode2 test_program causes the shell to freeze. If I have eclipse running the error message appears in the eclipse log, saying that the othernode1 and 2 basically don’t exist.



If I ssh to another node where I haven’t done the install process and run my test program it runs fine across several nodes.



I was wondering if you can tell me why the install process is corrupting my existing openMPI setup, not allowing me to run my test program across other nodes and why I am only seeing 1 machine in my PTP runtime.



Any help greatly appreciated as really would like to get to the bottom of this.



Thanks



Mark
