| RMS - Optimal Resource Management for Clusters

|
 Cluster
of workstations are designed to provide massive computational
power to users at low cost. These are cheap and readily
available alternative to specialized High
Performance Computing platforms.
Random submission of
tasks on clusters can cause some workstations to be
heavily loaded while other workstations are idle or
only lightly loaded hence killing the very purpose of
clusters of workstations.
C-DAC's PARAM series of super-computers are large clusters of high
performance workstations interconnected through low-latency,
high bandwidth communication networks. The major challenging
work for system administrators is to allocate the processing
capacity available in the locally distributed system
to facilitate its maximum usage.
 C-DAC's
Resource Management Software (RMS) manages, monitors
and analyzes the workload on the nodes in the cluster
and unites the nodes in the cluster for efficient execution
and management of programs. RMS supports sequential
and parallel (MPI) applications.
DESCRIPTION
RMS improves
the performance by scheduling the jobs on nodes depending
upon their load. It queues the jobs and schedules them
based on the availability of resources. Users can specify
the resources and RMS intelligently decides the nodes
based on requirements and availability. RMS also supports
heterogeneous environment having different operating
systems and hardware.
KEY FEATURES
- Remote job submission
- Supports the heterogeneous environment
- Job queuing
- Static load scheduling
- MPI Support
- Dynamic management of queues
- Enhanced configuration facilities
for super-user
- Fault Tolerance for master
and dispatcher
SYSTEM MODEL
Resource Management
Software consists of three modules:
- Master Node:
The Master Node queues the jobs from the users, and
dispatches them to the client nodes depending on their
resources and load.
- Dispatcher:
Dispatcher daemon runs on all the client nodes. They
spawn the jobs, report the status of the jobs and
also about the resources available to the master.
- Receptor:
RMS provides a set of commands for users and
system administrators to interact and configure. Backup
master node, dispatcher and master daemons provide
the necessary fault tolerance.
