(see the HOSTLIST EXPRESSIONS section below). Hostlists may also be specified to the -x option Other target node list options such as -a and -g (whenĪvailable). 'ssh:user1 host0' would use ssh to connect Username other than the default, or 'rcmd_type:' to specify an alternate A regex orįile name argument may also be preceeded by a minus `-' to exclude insteadĪ list of hosts may also be preceded by to specify a remote May also be optionally trailed by another '/', e.g. Regular expression on which to filter the list of hosts (a regex argument If the item begins with a `/' character, it is taken as a If the argument is preceded by a single `^'Ĭharacter, it is taken to be the path to file containing a list of hosts, If a host or hostlist is preceded by a `-' character, this causes those In hostlist format (See HOSTLIST EXPRESSIONS), or a single `-'Ĭharacter to read the list of hosts on stdin. The TARGETS list may include normal host names, a range of hosts No spaces are allowed in the comma-separated list. Target and or filter the specified list of hosts. Standard target nodelist options -w TARGETS. In these cases, the modules are incompatible and In some cases, options provided by modules may conflict withĮach other. OPTIONSThe list of available options is determined at runtimeīy supplementing the list of standard pdsh options withĪny options provided by loaded rcmd and misc modules. xcpu The xcpu module uses the xcpu service to execute remote commands. krb4 The krb4 module allows users to execute remote commands afterĪuthenticating with kerberos. mqsh Similar to qshell, but uses the mrsh protocol instead of the rsh protocol.

QSHELL_REMOTE_LD_PREOPEN environment variables will may be used and willīe remapped to LD_LIBRARY_PATH and LD_PREOPEN by the qshell daemon if set. Instead the QSHELL_REMOTE_LD_LIBRARY_PATH and Support, qshell does not directly support propagation of LD_LIBRARY_PATHĪnd LD_PREOPEN. Since pdsh needs to run setuid root for qshell

The following environment variable are alsoĪppended to the environment: RMS_RANK, RMS_NODEID, RMS_PROCID, RMS_NNODES,Īnd RMS_NPROCS. The current working directory, pdsh environment, and Elan capabilities qsh Allows pdsh to execute MPI jobs over QsNet. Remote nodes must be running mrshd(8) in order for the mrsh The mrsh protocol uses a credential based authentication, forgoing mrsh This module uses the mrsh(1) protocol to execute jobs on remote hosts. Ssh Uses a variant of popen(3) to run multiple copies of the ssh(1)Ĭommand. Pdsh -R exec -w foo ssh -x -l %u %h hostnameĪnd this command line would run grep(1) in parallel The following would duplicate using the ssh module to Username, and %n for the remote rank (To get %h for the target hostname, %u for the remote Parameters are substitued on the command line, including To execute, followed by any further arguments. Of the pdsh remote arguments is the local command exec Executes an arbitrary command for each target host. To run commands using the standard rsh(1) protocol. rsh Uses an internal, thread-safe implementation of BSD rcmd(3) The default rcmd module will also be displayed with theĪ list of rcmd modules currently distributed with pdshįollows. Modules is printed when using any of the -h, -V, or -L Modules, and so the list of available options may be differentįrom installation to installation.

This functionality is ultimately implemented via dynamically loadable Selected at runtime using the -R option (See OPTIONS below). RCMD MODULESThe method by which pdsh runs commands on remote hosts may be removing hosts that are 'down' from the target list),Īnd/or host selection options (e.g., -a selects all hosts fromĪ configuration file.). (replacing the standard rcmd(3) protocol used by rsh(1)), filtering The modules may provide a new connection protocol The core functionality of pdsh may be supplemented by dynamically That time out on the first command are not contacted for subsequentĬommands, and commands prefixed with an exclamation point will be Runs interactively, prompting for commands and executing them when If a remote command is not specified on the command line, pdsh In the process of connecting to the remote host. Pending threads are those that have not yet been initiated, or are still Threads may be canceled by issuing ctrl-Z within one second of ctrl-C. A second SIGINT within one second terminates the program. When pdsh receives SIGINT (ctrl-C), it lists the status of current To conserve resources on the initiating host while allowing some pdsh uses a 'sliding window' (or fanout) of threads Unlike rsh(1), which runsĬommands on a single remote host, pdsh can run multiple remote commands Pdsh - issue commands to groups of hosts in parallelĭESCRIPTION pdsh is a variant of the rsh(1) command.
