Re: [atlas-devel] Number of threads selection

[R. C. W. <rcw...@ls...>]

So far, it still must be compile-time chosen.  We need it for affinity, 
which is necessary when OS does a poor job of managing the threads.

Eventually I may be able to support run-time choice for the OpenMP 
implementation, which has its own scheduler (though in the cases where 
ATLAS used affinity in past it got horrible performance).  Right now, I 
have not yet gotten time to look at that part of the threading package, 
as I'm in the middle of big kernel redesign still.

Regards,
Clint
