SUMMARY:CView and NWPerf for Supercomputer Performance Collection and Disp
 lay.
DESCRIPTION:Workshop\nCollaborative Environments, Reproducibility, System 
 Administration, System Software, Tools, Workshop Reg Pass, HPC\n\nCView an
 d NWPerf for Supercomputer Performance Collection and Display.\n\nFelix\n\
 nCView is a full 3D interactive graphics tool for displaying collected Sys
 tem and Application performance data. Data is collected using various open
  source tools common on large clusters such as ganglia, collectl, or colle
 ctd. When collecting data on large scale systems with thousands of nodes t
 o tens of thousands of nodes, this data set becomes quite large over time.
  For example, on The Cascade System at the Environmental Molecular Science
 s Laboratory at PNNL one days collection of performance data stored as raw
  floats is about 2.5 Gigabytes of data. The CView Graphics environment all
 ows a user to easily visualize such data-sets. This allows System Administ
 rators to 'see' how the system is performing in near-time data streams. Sy
 stem Administrators and System Users use it for visualizing the performanc
 e of the whole systems or just the nodes involved in a specific job run. T
 he Systems 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 method a user can display data from any point in time and investigate
  various metrics at the system or job level.
