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.
Proxy Agent
The RMS communicates with proxy agents to gather information about the state of a target system. The proxy agent may be located on either a local or remote machine.
Proxy Agent Launch
The RMS is responsible for launching the proxy agent. On a local machine, this just involves executing a local process. To launch on a remote machine, the RMS must use an authenticated command service, such as ssh. Current plans are to utilize the Remote System Explorer (RSE) system to provide this remote proxy launch capability.
Proxy Session
One instance of a communcation channel between the RMS and a proxy agent is known as a session. A session only supports communication to a single proxy agent at a time. The mechanism used to effect communcation between the RMS and a proxy agent is not defined in this document, but can be any bi-directional communications channel (e.g. TCP/IP sockets, etc.)
