Hi there,

i just remembered what i was missing lately using parallel.for:

how about an override which allows for LONG indexes instead of INT. Yes, the current workaround is to use a cast, but that's ... ;)

Pointernil, thanks for the request. Support for In64 in Parallel.For is certainly something we're considering. What are you doing that you need Int64s? Is it that you are already using Int64 values but in the range of Int32 and are just trying to avoid a cast, or are you actually outside the bounds of what an Int32 can support?

@toub: 1) my index being typed with Long sneaked in by using FileStream.Seek method with large, sorry hudge files; this one takes a "long Offset" param;

2) PFX rocks!

3) Please have a serious talk with Anders or Mr.Erik Meijers ;) and have them wrap the lib with some syntactic sugar in the compilers.

4) When are you guys going to announce that OS level interface to co-processing units and the PFX support for that? ;)

Pointernil, thanks for the feedback, and I'm very glad you find Parallel Extensions useful. We're definitely considering Int64 support; others have suggested it's important, too.

As for Anders and Erik, we talk with them all the time :)

I am very much looking forward to the new .Net Parallel extensions being RTM'd. This Post from Stephen
