DescriptionIn situ compression is a compromise between traditional
post hoc and emerging in situ visualization and
analysis. While the merits and limitations of various
compressor options have been well studied, their
performance impacts on scientific simulations are less
clear, especially on large scale supercomputer systems.
This study fills in this gap by performing in situ
compression experiments on a leading supercomputer
system. More specifically, we measured the computational
and I/O impacts of a lossy wavelet compressor and
analyzed the results with respect to various in situ
processing concerns. We believe this study provides a
better understanding of in situ compression as well as
new evidence supporting its viability, in particular for
wavelets.
