Zodiac Element Library

Zodiac Communication Trace Component

Zodiac provides limited message trace reply over cycle accurate/packet-accurate networks such as Merlin. Zodiac currently uses a custom format but limited reply of OTF and OFT-2 traces is prototyped. Events are translated into the Hermes middleware emulation layer which provides communication capabilities and support for MPI semantics (message matching etc). The custom format uses the SIRIUS tracing library developed to prototype MPI communication tracing replay in SST.
