5.12. PopDist and PopRun
For PopRun on Pod systems, added functionality that automatically detects the RNIC interfaces to use for host-to-host communication. Refer to the section in the user guide on Network interfaces for more information about how to override the settings.
--vipu-clustercommand line option. Use the
--vipu-allocationoption instead. See the Configuration section in the PopDist and PopRun User Guide for more information.
--machinefilecommand line options. See the Configuration section in the PopDist and PopRun User Guide for more information.
popdist::isBackendInitializednow returns False if that backend has not yet been registered. This is a more intuitive result for the user than throwing an exception (which was the previous behaviour). If you are calling this function already, this new behaviour is what will happen. No further change required.
Improvements to the documentation:
documented that PopRun ignores
Add debug mode to PopRun. Add
--debugon the command line for advanced diagnostics.
Host SSH keys for multi-node systems should be automatically populated for all users. This is supported by the ability to forward the SSH key to the hosts specified.
Specify a key with
--distribute-ssh-key, answer the password prompt, and it will copy the key to all hosts specified by that flag.
Eliminate the need for passing of IP addresses/hostnames to PopRun. Host names can be read from a file.
--offline-modedoes not check for a V-IPU partition.
