Announcing GEOPM 3.0.0 release

[Siddhartha Jana]

Team,

GEOPM 3.0.0 has been released:
https://github.com/geopm/geopm/releases/tag/v3.0.0

The latest documentation is here:

• https://geopm.github.io 
• https://geopm.github.io/overview.html

As a reminder: the GEOPM project now has three major components:

1. GEOPM SystemD Service 

• Decouples session management requirements and the save/restore mechanism of HW controls, from HPC resource managers
• Sysadmin support for fine-grained access management on a per-feature and per-user basis
  
• Guide: https://geopm.github.io/service.html

2. GEOPM PlatformIO Library

• High-level abstraction of the underlying HW/SW knobs
• Integrates with the GEOPM Service 
• Vendor-neutral plugin architecture to support HW feature extension
• Reading signals: https://geopm.github.io/overview.html#microscope-read-telemetry-from-the-platform
• Writing controls: https://geopm.github.io/overview.html#gear-enact-hardware-based-settings
• Overview man page:  https://geopm.github.io/geopm_pio.7.html

3. GEOPM Runtime Library

• Automated profiling & optimization of applications based on end user objectives. 
• Leverages the PlatformIO and integrates with the GEOPM service
• Supports variety of application programming models: HPC and beyond
• Overview: https://geopm.github.io/runtime.html
  
• Getting started: https://geopm.github.io/overview.html#straight-ruler-use-the-runtime-to-measure-application-performance

Some of the highlights of version 3.0 release include:

• Enhancements to the GEOPM Service (geopmd) - a standalone component to the GEOPM project, alongside the hardware abstraction layer (GEOPM PlatformIO) and the automated optimization library (GEOPM Runtime)
• Runtime support for any Linux application (extending beyond basic MPI and HPC use cases)
• Improved Security Model 
• Communication between the GEOPM Runtime and the user application is managed by the GEOPM Service and is more secure. 
• Introduction to energy-aware resource management with PBS 
• Job launch support for PBS/PALS environments (in addition to Slurm and ALPS)

Features for the future releases:

• Enable GEOPM Service communication over gRPC
• Container-support for cloud environment
• Enhanced support for sysfs based device drivers
