Log:
Add XSBench
The US Department of Energy (DOE) has open-sourced a significant number of
so-called proxy applications (i.e. small applications, representative of our
larger workloads in some respects, intended for use as benchmarks and test beds
for various kind of porting exercises). Many of these are useful as compiler
tests, and I'd like to add these to our test suite. Doing so will increase the
representation within our test suite of HPC/scientific applications and allow
us to better track how Clang/LLVM is doing in this area. Scientific
applications are certainly a diverse group in themselves, and so my long term
goal is to add a significant number of these proxies to ensure good coverage.
Some months ago, I compiled a list of our open-source proxy applications
released by the various DOE laboratories
(https://gitlab.com/llvm-doe/public/wikis/DOEProxyApps). By my estimate, of the
approximately 40 proxy applications on that list, around half could be
reasonably added to our test suite. We're continuing to develop new proxies,
and so the number of suitable applications should grow somewhat in the future.
In any case, here's the first one: XSBench. This is a C application with a
straightforward reference output. It is designed to represent a key
computational kernel of the Monte-Carlo neutronics application OpenMC. The
builtin "small" test configuration is mostly suitable for our test suite - the
parameters have been adjusted slightly so that the test uses only ~27MB of
memory and runs in a few seconds.
As a reflection of my desire to add more of these applications, I've place this
in a subdirectory named DOE-ProxyApps-C (the idea being that the C++ proxy
applications will get a DOE-ProxyApps-C++ directory or similar).
