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