2023-08-30 UCX-settings update (Damian Alvarez, JSC)

Update type: SW Modules

The UCX-settings/*CUDA modules also set UCX_RNDV_FRAG_MEM_TYPE=cuda. This enables the GPU to initiate transfers of CUDA managed buffers. This can have a large speed-up in case Unified Memory (cudaMallocManaged()) is used, as staging of data is avoided.

Change in user installations

  • The module structure has been changed so $MODULEPATH is not expanded depending on the existence of the $PROJECT variable. Now the variable used is $USERINSTALLATIONS, so the project software is not automatically activated when using jutil.

2022-02-07 Enable user slices (Sebastian Achilles, JSC)

Per-slice-limits enabled for users. This means, even with multiple sessions a user is limited to the given amount of cpu time slots.

The value was set to 2000%. The value is given in % of a single core, i.e. 2000% means 20 full cores all of the time or 40 core half of the time, …
