Synopsis function LAM_Start(nslaves, rpi, hosts) Description 59
LAM_Start invokes lamboot (if required) and MPI_Init (if required). Usage: LAM_Init [ ( NSLAVES [, RPI [, HOSTS] ] ) ] LAM_Start boots LAM and initializes MPI to match a given number of slave hosts (and rpi) from a given list of hosts. All three args optional. If they are not defined, HOSTS are taken from a builtin HOSTS list (edit HOSTS at the beginning of LAM_Start.m to match your cluster) or from the bhost file if defined through LAMBHOST (in this order). If not defined, RPI is taken from the builtin variable RPI (edit it to suit your needs) or from the LAM_MPI_SSI_rpi environment variable (in this order).
