August 6, 2008 - Sandia Releases Application Traces
The research community has long desired traces at large-scale for real applications as synthetic benchmarks lack the fidelity and credibility of actual traces. As part of the Petascale Data Storage Institute (PDSI), Sandia researcher, Lee Ward, has released input-output (I/O) system-call trace data from two representative runs of Sandia’s ALEGRA simulation shock and multiphysics code suite.
The two runs, performed on the Sandia/NNSA RedStorm supercomputer, captured information about four checkpoint dumps, run logs, and terminal I/O. The two runs used 2,744 nodes and 5,832 virtual nodes, respectively. Links to race data and a short paper describing format and the environment from which the data was obtained follow.
