Grappa running in the Amazon cloud, using StarCluster.
Create your config file by running python create_config.py. The config is
written to grappacluster.config.
Start a new cluster named mygrappacluster. See starcluster for other options.
cluster -c grappacluster.config start -s 2 -i r3.xlarge mygrappacluster
When the cluster has started, ssh into the master.
cluster -c grappacluster.config sshmaster mygrappacluster
grappa-starcluster uses starcluster's default sgeadmin user for running MPI jobs. We suggest using sgeadmin for everything, other than when you require root.
geadmin
Do this once to create your MPI host file
'node[0-9]\|master' /etc/hosts >~/hosts
In the home directory, you'll find grappa/ with everything already default configured and
installed. If you ever need to re-configure, you can use the command in ~/build_grappa.sh.
Let's run an example job to make sure things work.
/grappa/build/Make+Release
-j demo-hello_world
un -np 12 --hostfile ~/hosts -- applications/demos/hello_world.exe
If your cluster has 2 nodes then the output should look something like:
