Motivations

• Workstation clusters have off late become a
  cost-effective solution for HPC ? .
• C-DACs PARAM OpenFrame is a large cluster of
  more than 40 Ultra-4 workstations interconnected
  through low-latency, high bandwidth communication
  networks.
• Monitoring such huge systems is a tedious and
  challenging task since typical workstations are
  designed to work as a standalone system, rather
  than a part of workstation clusters.
• System administrators require tools to
  effectively monitor such huge systems. PARMON
  provides the solution to this challenging problem.

PARMON - Salient Features

• Online creation of Node and Group database
• Allows to monitor system activities at Component,
  Node, Group, or entire Cluster level monitoring
• Designed using state-of-the-art Java technology
• Monitoring of System Components
• CPU, Memory, Disk and Network
• Allows to monitor multiple instances of the same
  componet.
• Facility for definition of events and automatic
  notification
• Miscellaneous facilities Message broadcast,
  Invocation of system management commands (halt,
  reboot, etc.), System Information Configuration
• PARMON provides GUI interface for initiating
  activities/request and presents results
  graphically.

PARMON Implementation

• Server
• Multithreaded using POSIX and Solaris
• Developed using C as it need to access system
  internals
• It is a stateless server
• Client
• Developed using Java
• Java features are extensively used..
• New Window is created for each client request,
  which interacts with server
• Threads are used extensively to while creating
  online resource utilization meters
• Dynamically configures with changes to node date
  base.

Setting up of PARMON

• Server installation invocation
• Binding to port
• Rights (requires root permission for full
  functionality)
• parmond or parmond ltport-nogt(either at boot
  time or on-line)
• Needs to be loaded on all nodes to be monitored
• Client installation invocation
• Java based client (client machine can be
  PC/workstation supporting JVM)
• CLASSPATH (pointing to classes.zip, parmon.jar)
• jar file (parmon.jar)
• java parmon or java parmon ltport-nogt

PARMON Integration with other Products

• PARMON can send resource utilization information
  to any other product if protocols are made
  available

Node 1
parmond
Node N
PARAM online bulletin board

Conclusions and Future Directions

• PARMON successfully used in monitoring PARAM
  OpenFrame Supercomputer, which is a cluster of 48
  Ultra-4 workstations running SUN-Solaris
  operating system.
• Portable across platforms supporting Java
• Comprehensive monitoring support and GUI
• PARMON supports Solaris and Linux clusters and
  planned for supporting NT clusters.
• Can easily be extended to support web-based
  monitoring of clusters, by creating a interface
  server (running on web-server) between client and
  PARMON server running on cluster nodes.
