Pegasus 4.9.1 Released

with No Comments

We are happy to announce the release of Pegasus 4.9.1 . Pegasus 4.9.1 is a minor bug fix release and includes a major change to how transfers are handled for containerized jobs. Pegasus 4.9.1 also includes support for Shifter.

Until Pegasus 4.9.0 the transfers for the jobs were conducted on the host node in Pegasus Lite job before the application container was launched. However, this limited the ability for users to use transfer protocols that were not installed on the host OS.  Starting 4.9.1 the transfers happen within the application container.
