Overview

This is a preliminary design for the PTP Resource Management proxy communication protocol. This protocol is used to communicate between the Resource Manager System in Eclipse, and a lightweight proxy agent running on a target system. The primary purpose of the protocol is for system monitoring, process launch, and process control activities.

Resource Manager System

The Resource Manager System (RMS) is an Eclipse plugin that manages interaction with arbitrary resource managers. A resource manager in this context, is anything that provides program launch and monitoring services on a target system. Typically, a resource manager will be a job scheduler (e.g. LSF, LoadLeveler, PBS, etc.) running on a large multi-user system. Other types of resource managers include the Open Runtime Environment (ORTE) which is part of the OpenMPI distribution, or the MPICH2 runtime system. The RMS is responsible for populating an internal model in Eclipse which provides a cached representation of the system and program state. Various user interface views are available to inspect and interact with this model. Details of the RMS are provided in a separate document PTP/designs/rms.
