ORCA 5.0.0 is available in Hydra¶
The recent major release of ORCA version 5.0.0 is now installed in Hydra. You can load it with the module
We have identified a bug with this new release that impacts parallel jobs requesting a single core per node (
ppn=1). Jobs using ORCA 5.0.0 in parallel should always request more than one process per node, which is the most common configuration. Serial jobs (
nodes=1:ppn=1) are not affected by this bug.
We also added a new section in our Software documentation for ORCA with an example parallel job script to use in Hydra.
