IPython cluster startup. This starts a controller and engines using various approaches. Use the IPYTHONDIR environment variable to change

For detailed help on each, type "ipcluster TYPE --help". Briefly:
local run a local cluster
mpirun run a cluster using mpirun (mpiexec also works)
mpiexec run a cluster using mpiexec (mpirun also works)
pbs run a pbs cluster
ssh run a cluster using ssh, should have ssh-keys setup
OPTIONS
-h, --help
show help message and exit
EXAMPLE
