Splash-3 is a benchmark suite based on Splash-2 but without data races. It was first presented at [ISPASS'16](TODO: Not available on IEEE just yet).
The version found here is a refined version of the one used in the ISPASS paper. The main difference is that it is based on the Modified Splash-2 suite, which, among other things, fixes issues related to running Splash-2 on x86-64, as well as lots of warnings. While working on the release version of Splash-3 we realized that we are duplicating a lot of the effort already taken by Modified Splash-2, so we decided to port our Splash-3 patchset on top of Modified Splash-2.
Modified Splash-2 also changes every int to long, which is something that we
only partially did for the version discussed in the paper, so we do expect some
differences in the memory footprint of the applications. However, everything
else, such as the algorithms or the synchronization characteristics of the
applications remain unchanged, making the overall performance difference between
this version and the ISPASS version minimal.
There is no need to install Splash-3. All you need to do is set the BASEDIR
variable in codes/Makefile.config to point to the full path of the codes
directory.

The first release of Splash-3 is tagged as v3.0. Small fixes might be
published untagged on the master branch, as long as they do not significantly
affect the performance or other characteristics of the applications. If such
changes were to be published, then a new tag will be created and the master will
no longer be considered to contain version 3.0.
It is also possible to access the original and the Modified Splash-2 codes.
They are tagged as v2.0 and v2.0M respectively.
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].

Due to popular demand, some of the locks around some of the "benign" assignment
races have been marked as optional. If you want to disable those locks, pass the
option -DWITH_NO_OPTIONAL_LOCKS to the compiler. IT IS HIGHLY DISCOURAGED TO
DO SO. The applications have not been tested without those locks, and even the
"benign" data races can cause undefined behavior.
