- NAME
-
cstest - test PM over a whole cluster
- SYNOPSIS
-
% cstest [options]
- DESCRIPTION
-
Cstest tests PM over a whole cluster.
- NOTICE
-
Cstest executes the same executable file on the same directory
on which cstest is invoked using rsh(1) on all nodes under testing.
By this reason, the host on which cstest must be able to rsh(1) to all cluster nodes to be tested.
Next, it must be possible to access the same executable file
by copying the file to all nodes or
by any file sharing facilities such as NFS.
Further, to chdir to the same directory,
an environment variable PWD must be set as the logical path
of the working directory on which cstest is invoked.
Some shells such as tcsh, bash and zsh
set PWD correctly.
If other shells are used with automount or
amd to share files,
and the physical path of the working directory is not same as
the logical path of it, PWD must be set manually.
- OPTIONS
-
-type device-
Device is used as the PM device type.
Default is "myrinet".
-config config_file-
Config_file is used as the PM configuration file.
Default is "pm.cnf".
-trunk[trunk_num] config_file-
This option is only effective to network trunking of
PM/Ethernet.Trunk_num is set to trunk number(0,1,2...) and,
config_file is used as the PM configuration file for the
trunk network. (Ex. -trunk0 ether-1.conf -trunk1 ether-2.conf )
-firmware firmware_file-
Firmware_file is used as the NIC firmware file.
Default is "pm.mcp".
-agent agent_command-
If the device type is "agent", this argument is needed to specify
the agent command name of PM/Agent.
Currently only "pmaudp" which means UDP communication agent is
available as the agent command name.
-chan chan-
Chan is used as the PM channel number for testing.
Default is zero.
-context ctx-
Ctx is used as the PM context number for testing.
Default is zero.
-len length-
Length byte messages are used for testing.
Default is 8 bytes.
-count count-
This option specifies the number of tests.
Default is infinity.
-pe num_pe-
Num_pe PEs are tested.
Default is all PEs of the cluster.
-base base_pe-
Base_pe is used as the first PE number.
Default is zero.
-burst-
A burst transfer is used for testing.
This is the default.
-ping-
A ping-pong transfer is used for testing instead of a burst transfer.
-v-
-verbos-
Show some messages while testing.
Default is that no messages are shown except errors.
- EXAMPLE
-
% cstest -v -pe 32 -ping
Execute a ping-pong transfer test on 32 PEs.
- ERRORS
-
Cstest outputs the following error message when any error occurs:
- node_name(pe#) function: error
- function detects error on the node.
- node_name(pe#) function: Operation timed out
- function failed for a long time on the node.
- node_name(pe#) Signal: Interrupted system call
- Testing was interrupted by a signal on the node.
