Traditional parallel applications have exploited regular parallelism, based on parallel loops. Only a few applications exploit sections parallelism. With the release of the new OpenMP specification (3.0), this programming model supports tasking. Parallel tasks allow the exploitation of irregular parallelism, but there is a lack of benchmarks exploiting
tasks in OpenMP.
With the current (and projected) multicore architectures that offer many more alternatives to execute parallel applications
than traditional SMP machines, this kind of parallelism is increasingly important. And so, the need to have some set of benchmarks to evaluate it.
In this paper, we motivate the need of having such a benchmarks suite, for irregular and/or recursive task parallelism.
We present our proposal, the Barcelona OpenMP Tasks Suite (BOTS), with a set of applications exploiting regular and
irregular parallelism, based on tasks.
We present an overall evaluation of the BOTS benchmarks in an Altix system and we discuss some of the different experiments that can be done with the different compilation
and runtime alternatives of the benchmarks.
