SUMMARY:CView and NWPerf for Supercomputer Performance Collection and Disp
 lay.
DESCRIPTION:Evan Felix (Pacific Northwest National Laboratory)\n\nCView is
  a full 3D interactive graphics tool for displaying collected System and A
 pplication performance data. Data is collected using various open source t
 ools common on large clusters such as ganglia, collectl, or collectd. When
  collecting data on large scale systems with thousands of nodes to tens of
  thousands of nodes, this data set becomes quite large over time. For exam
 ple, on The Cascade System at the Environmental Molecular Sciences Laborat
 ory at PNNL one days collection of performance data stored as raw floats i
 s about 2.5 Gigabytes of data. The CView Graphics environment allows a use
 r to easily visualize such data-sets. This allows System Administrators to
  'see' how the system is performing in near-time data streams. System Admi
 nistrators and System Users use it for visualizing the performance of the 
 whole systems or just the nodes involved in a specific job run. The System
 s at PNNL use the NWPerf software, backed by a Ceph Object store to route 
 and store the performance data our clusters. By storing the data this meth
 od a user can display data from any point in time and investigate various 
 metrics at the system or job level.\n\nTag: Collaborative Environments, Re
