Splash-4 Benchmark Suite

Splash-4 is a benchmark suite based on Splash-3 but with enfasis in atomic instructions. It was first presented at ISPASS'21.

Building and Running

Splash-4 does not require any special installation step.

In order to build Splash-4, a relatively modern C compiler with C11 support is required. In addition, the M4 macro processor is necessary for generating the source files in the first place. On Ubuntu and similar systems, you can install the m4 and ivtools-dev packages.

Some benchmarks expect their inputs to be at very specific paths relative to the working directory, so it is recommended to change the working directory to the benchmark folder before executing it.

Recommended Inputs

The following are the recommended inputs for running Splash-3 in a simulator. The symbol '#' is a placeholder for the number of threads. These inputs are based on the original Splash-2 characterization paper by Woo et al. [1].

Known Issues

If OCEAN (either version) segfaults during initialization, try reducing the IMAX and JMAX values in decs.h.
It is recommended to change the working directory to the benchmark's directory.
