An automatic generator of benchmarks for frameworks supporting task with dataflow dependencies

A Benchmark Generator

This tool takes as input a YAML file describing tasks, data and dependencies. Using this file, it generates a program creating and executing those tasks, using one of the frameworks supported.

Code generation is done by templates. Add a new template do add support for another target or kernel.

The yaml file must respect some constraints:

• the format must respect:

  • number of tasks
  • number of datas
  • list of data
    • each data has an id and a size
  • list of tasks
    • each task has a name, a numallocs, a numargs, a numchildren,
    • each task has the list of allocs, list of args, list of children
    • each task has a weight

• Tasks are in a valid topological order.

• Children list are in a valid topological order.

• the file represent a creation tree that is valid for the target framework.

• the uid of the datas are between 0 and M-1, in order.

Frameworks

Currently support XKaapi, StarPU, OpenMP 4.0 (via OmpSs) and Quark

Input Generation

It should be possible to automatically generate the input to this program too. Currently, this is done in the ggen tool.

Input examples are in the examples directory. Note that Quark requires the flat version, StarPU and OpenMP the flat or cluster version, and XKaapi support all of them.
