Re: [Starpu-devel] OpenMP

You can certainly use the examples provided with StarPU to test your new scheduler. It is however very difficult to tell you which specific benchmark to use unless you tell us more about your scheduler.

Concerning the possible benefits of tasks against thread, i would advise you to read any advanced course on parallel programming.

Cheers,

 Sir, you have very clearly said that starpu can be used by researchers to plug in their schedulers, to experiment.

 Thanks for making scheduler as a plug-in into starpu.

 Now, i wish to try new scheduling methods.

 Which benchmarks to use ? Should i use the ones given in examples folder.

 Are there are few more benchmarks to try ?

 I have read about task scheduling.

 According to you, which applications would be greatly benefited using tasks, instead of threads only.

 Please mention few such applications.

 last query - how are threads scheduled by starpu ?

with best wishes

See paragraph 5.9 "Parallel Tasks" of the StarPU handbook.
