the current working directory, pdsh environment, and Elan capabilities

appended to the environment: RMS_RANK, RMS_NODEID, RMS_PROCID, RMS_NNODES,

Set the rail bitmask for a job on a multirail system. The default
railmask is 1, which corresponds to rail 0 only. Each bit set in
the argument to \fI-r\fR corresponds to a rail on the system, so
a value of 2 would correspond to rail 1 only, and 3 would indicate

.SH "rms module options"
The \fBrms\fR module allows pdsh to target nodes based on an RMS
resource. The \fBrms\fR module is typically called after all other
node selection options, and if no nodes have been selected, the
module will examine the RMS_RESOURCEID environment variable and
attempt to set the target list of hosts to the nodes in the
RMS resource. If an invalid resource is denoted, the variable is
silently ignored.
.SH "SDR module options"
The SDR module supports targeting hosts via the System Data Repository
on IBM SPs.
.I "-a"
Target all nodes in the SDR. The list is generated from the
"reliable hostname" in the SDR by default.
.I "-i"
Translate hostnames between reliable and initial in the SDR, when applicable.
If the a target hostname matches either the initial or reliable hostname
in the SDR, the alternate name will be substitued. Thus a list composed
of initial hostnames will instead be replaced with a list of reliable hostnames.
For example, when used with \fI-a\fR above, all initial hostnames in
the SDR are targeted.
.I "-v"
Do not target nodes that are marked as not responding in the SDR on
the targeted interface. (If a hostname does not appear in the SDR, then
that name will remain in the target hostlist.)

In combination with \fI-a\fR, include all partitions.

The \fBnodeattr\fR module supports access to the genders database
via the nodeattr(1) command. See the \fBgenders\fR section above
for a list of support options with this module. The option usage
with the \fBnodeattr\fR module is the same as \fBgenders\fR, above,

with \fI-a\fR or \fI-g\fR. \fBNOTE\fR: This module will only
work with very old releases of genders where the \fBnodeattr\fR(1)
command supports the \fI-r\fR option, and before the libgenders
API was available. Users running newer versions of genders
will need to use the \fBgenders\fR module instead.

Output from multiple processes per node may be interspersed when using qshell

The number of nodes that \fBpdsh\fR can simultaneously execute remote
jobs on is limited by the maximum number of threads that can be created
concurrently, as well as the availability of reserved ports in the rsh
