[mpich-discuss] Information about output of slog2print

Wed Feb 15 12:02:50 CST 2012

Reading the slog2 paper below

"An Efficient Format for Nearly Constant-Time Access
to Arbitrary Time Intervals in Large Trace Files"

in http://www.mcs.anl.gov/research/projects/perfvis/publications/index.htm
should answer your questions.  If not, ask again.
Also, not all fields in slog2 format is used in jumpshot.
