[petsc-users] installation on cloud platform

[Satish Balay]

Are you interested in using 1 node [with multiple cores] - or multiple
nodes - aka cluster on amazon?

For a single node - I don't think any additional config should be
necesary [/etc/hosts - or ssh keys]. It should be same as any laptop
config.

Its possible that 'hostname' is not setup properly on amazon nodes - and
MPICH misbehaves.  In this case - you might need any entry to
/etc/hosts. Perhaps something like:

echo 127.0.0.1 `hostname` >> /etc/hosts

If cluster - then there might be a tutorial to setup a proper cluster with AWS. Googles gives
http://cs.smith.edu/dftwiki/index.php/Tutorial:_Create_an_MPI_Cluster_on_the_Amazon_Elastic_Cloud_%28EC2%29

BTW: --download-mpich is a convient way to install MPI. [we default to
device=ch3:sock]. But you might want to figureout if there is a better
performing MPI for the amazon config.  [perhaps mpich with nemesis
works well. Or perhaps openmpi. Both are available prebuit on
ubunutu...]
