Abstract
Despite supercomputers deliver huge computational power,
applications only reach a fraction of it. There are several factors
limiting the application performance, and one of the most important
is the single processor efficiency because it ultimately dictates the
overall achieved performance. We present the folding mechanism, a
process that combines measurements captured through minimal
instrumentation and coarse-grain sampling ensuring low time
dilation (less than 5%). The mechanism reports instantaneous
performance and source-code references for optimized binaries
accurately by taking advantage of the repetitiveness of many
applications, especially in HPC. The mechanism enables the
exploration of the application performance and guides the analyst to
source-code modifications.
