bpmaster -- Daemon for cluster control and communication.
bpmaster [options] [-h ] [-V ] [-d ] [-v ] [-i ] [-c file] [-m file]
This daemon is part of the
BProc package and is installed by
default. It is the controller and message/IO manager for all the compute
nodes and must be running for the cluster to function.
bpmaster is started by the ClusterWare initialization script, along with
BProc daemons, and forks a copy of itself for IO forwarding.
With normal cluster operation there should be 2 PIDs for bpmaster.
Type ps -x |grep bpmaster to check.
The bpmaster daemon may be restarted at any time by using a ClusterWare
restart, but note that this will cause all nodes to reboot.
During normal operations, use a service
reload to enable
/etc/beowulf/config configuration changes.
