Futhark implementations of various benchmarks. The intention is that these implementations are of existing published benchmarks, and thus show where we do well or poorly. We highly encourage everyone to make use of it when evaluating Futhark performance. The following contains instructions on how to do that.
The recommended method for running all benchmarks is
futhark bench * --backend=opencl --ignore-files /lib/
This uses the
opencl backend, and ignores the test suites of any
embedded libraries (which are usually too small to be useful
benchmarks, and would merely be noise). You can replace
another backend. While the
c backend is likely too slow to be
practical for many of the benchmarks, the
cuda backend should
You can also add
--ignore-files /micro/ to ignore the
microbenchmarks of single language constructs, which are often not
very interesting, but do take a long time to run.
If necessary, you can use
--pass-option to pass more options to the
generated Futhark programs. This may be necessary if you are using
the OpenCL backend on a system with more than one OpenCL device, and
you wish to use another device than the default. For example, to ask
Futhark to use the first device that contains "NVIDIA" in its name,
you could use
If you wish to analyse the performance results with a program, passing
futhark bench may be useful.

Many of the input/output files are stored in a simple binary format for performance and space reasons. This format is documented in the Futhark reference manual, and can be converted to a textual representation via the futhark dataset tool.
