Hello,
I intend to setup a ready-to-go MPI Cluster on OpenNebula from a VM image. Is
it possible? Can each VM know its role (master or slave), as well as other VM,
to fill in the mpdhost file? I don't know much about context yet.
Thanks for any explanation.
Best regards,
Quynh

Yes, clusters are particularly easy on this environment, I work with our
analytics group on hadoop clusters. The most important thing to do is
install good parallel computing utilities like pdsh and have ssh
equivalency setup, then creating a cluster of machine sis realyl easy
because you get N mac
, or 1 for all?
I'm looking forward to your sharing.
Cheers,

But we are using virtual machines, so changes and configuration on each virtual
node will be lost when it terminates. (1)
Every time we launch a cluster, we may change the number of slave nodes, up to
the problem size. (2)
So could you b
