Lastest release
ClusterShell is an event-driven open source Python library, designed to run local or distant commands in parallel on server farms or on large Linux clusters. It will take care of common issues encountered on HPC clusters, such as operating on groups of nodes, running distributed commands using optimized execution algorithms, as well as gathering results and merging identical outputs, or retrieving return codes. ClusterShell takes advantage of existing remote shell facilities already installed on your systems, like SSH.
User tools
ClusterShell also provides clush, clubak and nodeset, three convenient command-line tools that allow traditional shell scripts to benefit from some of the library features:
- clush: issue commands to cluster nodes and format output
Example of use:
$ clush -abL uname -r node[32-49,51-71,80,82-150,156-159]: 2.6.18-164.11.1.el5 node[3-7,72-79]: 2.6.18-164.11.1.el5_lustre1.10.0.36 node[2,151-155]: 2.6.31.6-145.fc11.2.x86_64
See man clush for more details.
- clubak: improved dshbak to gather and sort dsh-like outputs
See man clubak for more details.
- nodeset: compute advanced nodeset/nodegroup operations
Examples of use:
$ echo node160 node161 node162 node163 | nodeset -f node[160-163] $ nodeset -f node[0-7,32-159] node[160-163] node[0-7,32-163] $ nodeset -e node[160-163] node160 node161 node162 node163 $ nodeset -f node[32-159] -x node33 node[32,34-159] $ nodeset -f node[32-159] -i node[0-7,20-21,32,156-159] node[32,156-159] $ nodeset -f node[33-159] --xor node[32-33,156-159] node[32,34-155] $ nodeset -l @oss @mds @io @compute $ nodeset -e @mds node6 node7
See man nodeset for more details.
