Variorum 0.7 released

[Tapasya Patki]

Hi everyone:

We’re pleased to announce that Variorum v0.7 has now been released. The current version now has power management support for all upcoming DOE exascale platforms: El Capitan, Aurora and Frontier, as well as the ARM Neoverse N1. This is a major release and provides several useful features, including a new GPU power capping API for AMD, NVIDIA and Intel GPUs, and an improved non-intrusive monitoring support through powmon.

To get to know Variorum as well as our team better, please watch our recently recorded video that explains how Variorum fits into an end-to-end PowerStack that we are working towards: https://www.youtube.com/watch?v=rgJGgPERBao 

We are now working toward further enhancing support for multi-architecture builds (e.g supporting power monitoring and capping where CPU and GPU vendors are different or have different underlying mechanisms requiring builds across devices). As always, we’re happy to answer questions and welcome any contributions/feedback.  Release notes follow.

Sincerely,
Tapasya, on behalf of the LLNL Argo PowerStack Team.
