Task #2395: break up commrec - GROMACS - GROMACS development

Task #2395

Status:

In Progress

Priority:

Assignee:

Category:

Target version:

Difficulty:

uncategorized

Description

t_commrec currently handles lots of things and goes lots of places. We should break it into pieces as suggested in the checklist.

This will make it much easier to deploy modules that might be exposed by an API, or implement standard interfaces for command-line options, etc.

Checklist

multi-simulation handler, including communicator
physical node communicator - removing various places where we make temporary ones
DD aspects
duty aspects - PP vs PME vs both

Remove commrec from hardware detection

This is preparatory refactoring for aspects of #2395

The OpenCL logic was ineffective, because duty is not yet decided, and
anyway we might soon want the detection on PME-only ranks.

Replaced the thread-MPI single-rank assertion with a more direct
implementation.

Minimized contents of detecthardware.h
