Subject: Re: [OMPI devel] orte question
From: Greg Watson (g.watson_at_[hidden])

Hi Ralph,

I'd like three things :-)

a) A --report-jobid option that prints the jobid on the first line in a form that can be passed to the -jobid option on ompi-ps. Probably tagging it in the output if -tag-output is enabled (e.g. jobid:<jobid>) would be a good idea.

b) The orte-ps command output to use the same jobid format.

c) A more easily parsable output format from ompi-ps. It doesn't need to be a full blown XML format, just something like the following would suffice:

jobid:719585280:state:Running:slots:1:num procs:4
process_name:./x:rank:0:pid:3082:node:node1.com:state:Running
process_name:./x:rank:1:pid:4567:node:node5.com:state:Running
process_name:./x:rank:2:pid:2343:node:node4.com:state:Running
process_name:./x:rank:3:pid:3422:node:node7.com:state:Running
jobid:345346663:state:running:slots:1:num procs:2
process_name:./x:rank:0:pid:5563:node:node2.com:state:Running
process_name:./x:rank:1:pid:6677:node:node3.com:state:Running

I'd be happy to help with any or all of these.

Cheers,
Greg
