Chapel Nightly Performance Graphs
The following graphs are used by the Chapel development team in order to track Chapel performance over time. It should be noted that the graphs show changes not only in the Chapel compiler, runtime, and libraries, but also to the tests themselves, and the systems on which the tests are run. To the extent possible, the graphs contain annotations indicating causes of nontrivial changes.
Since Chapel is open-source, community members are encouraged to submit their own Chapel performance tests to be included in these graphs. For an introduction to what is needed to submit a new performance test, see our GitHub How to Contribute as well as the developer's documentation for creating Chapel performance tests.
Primary Configurations:
chapcs runs our single-locale performance suite on a node with 24 cores (48 HT) and 256 GB RAM
16-node-xc runs our multi-locale performance suite on 16 nodes of a Cray XC with 28 cores (56 HT) and 128 GB RAM per node
16-node-cs runs our multi-locale performance suite on 16 nodes of a Cray CS with 36 cores (72 HT) and 128 GB RAM per node
comm-counts runs our communication count tests
shootout runs the shootout benchmarks on a machine with hardware and software that closely mimics the real CLBG site
chapcs/no-local runs our single-locale suite with --no-local
chapcs/llvm runs our single-locale suite with --llvm
chapcs/clang runs our single-locale suite with clang as the backend compiler
1-node-xc runs our single-locale suite with intel, cray, and gcc backends on a Cray XC node
comp-default runs our full test suite with compilation time tracking enabled
