DescriptionHigh performance MPI applications employ
nondeterministic asynchronous communication to achieve
greater performance. However, this nondeterminism can
significantly hamper debugging. Various software tools
have been developed to control nondeterminism in HPC
applications, but a high-level application-agnostic
taxonomy for this nondeterminism is absent and limits
these tools' effectiveness in practice. We propose to
address this need by extracting common nondeterministic
communication motifs from representative
applications.
We present a first step toward capturing nondeterminism motifs by way of a workflow for detecting and summarizing sender nondeterminism in HPC applications.
