Quark scheduler

Postby cn_cologne » Tue Aug 23, 2011 12:39 pm

Concerning the used Quark Scheduler i have two questions.

- Is the schedular mainly lock-free, such as intels TBB, to allow
'real' fine grain parallelism? Acctually i roughly debugged the code, and
saw alot of mutexes, so I was just wondering....

- What was the objective, not to use other available solutions, such as
OpenMP or TBB, which relies on a work-stealing concept?

thanks for any help,

For dense linear algebra your options are: StarSs, StarPU and Quark.
OpenMP, Intel TBB or Cilk are not going to do the right thing.
