[mpich-discuss] mpiexec - specifying list of hosts in command line without file

[Yauheni Zelenko]

Thank you for help, Pavan!

It's also may be useful to specify number of instances, like in host file (i.e. host:number).

Never mind the ticket -- it was simple enough that I went ahead and
added it to trunk in r6812 (usage is "-hosts foo,bar"). You can download
