Abstract:
Performance modelling for scientific applications is an important task
for assessing potential performance, bottlenecks assist in
hardware procurement for HPC systems. Recent progress on
communication tracing provides novel opportunities for communication
modelling.
We contribute a fundamentally novel approach. By extrapolating
communication traces ution time of a parallel application, a
set of traces for smaller number of nodes provides the base to
synthetically generate a trace for larger number of nodes. The
extrapolated larger trace can subsequently be replayed to empirically
detect scalability problems or analyzed to detect communication
patterns or determine constraints on scalability, which is without
precedence.
