bpslave – This program is the BProc distributed process space slave daemon that executes on each compute node.
bpslave [options] [-h] [-V] [-l logfacility] [-r] [-i] [-d] [-s addr] [-c dir] [-p port] [-m file] [-v]
The bpslave daemon is part of the
BProc package, and is
installed by default. It is the controller and message and I/O manager
run on each compute node, and must be running for the node to function.
bpslave is started by the Scyld compute node init process, which
sets parameters based on what is passed in through the kernel command
line option in the
/etc/beowulf/config file. All parameters of the
bpslave daemon are not accessible via the “kernelcommandline”
The bpslave daemon is not intended to be run from the command line, nor otherwise executed started, except implicitly by the compute node init process.
The following options are available to the bpslave program. These
options are mainly intended for using
BProc in a standard linux
environment where the master and compute nodes both have full system
Show this message and exit. If
-his the first option, all other options will be ignored. If
-his not the first option, the other options will be parsed up to the
-hoption, but no action will be taken.
Print version information and exit.
- -l logfacility
Log to this log facility (default=daemon).
Automatic reconnect on error or lost connection.
BProcversion mismatches (dangerous).
Do not daemonize self.
- -s addr
Connect from source address
- -c dir
Set library cache to
- -p port
Set library cache file request port to
port. The default is port 932, which can be overridden by a config file directive
- -m file
Enable message trace to
Increase verbose level (implies
- Masterhostname [[port]]
The host name and (optionally) the port number of the bpmaster daemon. The default is port 933, which can be overridden by a config file directive
