bpslave¶
Name¶
bpslave -- This program is the BProc distributed process space slave daemon that executes on each compute node.
Synopsis¶
bpslave [options] [-h] [-V] [-l logfacility] [-r] [-i] [-d] [-s addr] [-c dir] [-p port] [-m file] [-v]
Description¶
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"
keyword in /etc/beowulf/config
.
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.
Options¶
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
installs.
-h | Show this message and exit. If -h is the first option, all other
options will be ignored. If -h is not the first option, the
other options will be parsed up to the -h option, but no action
will be taken. |
-V | Print version information and exit. |
-l logfacility | Log to this log facility (default=daemon). |
-r | Automatic reconnect on error or lost connection. |
-i | Ignore BProc version mismatches (dangerous). |
-d | Do not daemonize self. |
-s addr | Connect from source address addr . |
-c dir | Set library cache to dir . |
-p port | Set library cache file request port to port . The default is port
932, which can be overridden by a config file directive server beofs2 . |
Debugging options:
-m file | Enable message trace to file . |
-v | Increase verbose level (implies -d ). |
- 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
server bproc
