are any of you guys able to get it to compile (with 6.10 or 6.8.3)? we get what looks like some build errors coming from the ndp source. just wanted to check and see if it's something we're doing wrong or not. thanks all, james On Tue, Nov 25, 2008 at 4:07 AM, Simon Peyton-Jones wrote:

Very much actively! Roman is working hard on the library right now. I'm ccing him.

Does anyone know if this library is being actively maintained? We had some trouble getting it to build with the 6.10 sources, and it didn't look it had been updated in a while, so I guess I just wanted to check and see if anyone knew about it.

Thanks all! James

It surely build. It is part of the standard distribution of GHC 6.10.1. However, you haven't told us what you are exactly using. If you just get the standard 6.10.1 tarball together with the extralibs tarball from http://haskell.org/ghc/download_ghc_6_10_1.html#sources will that not compile for you? Manuel

now i see, i think this is what i'm looking for...though i'm a little confused. the website says that the 'speed without convenience' stuff is in a separate package called 'ndp' (so libraries/ndp), which is what we pulled from darcs and will not compile. but this stuff under libraries/dph looks awfully similar. has everything been moved?

Yes, it has been moved and we need to update the wiki page. Sorry, I didn't realise that this was what you were looking at. Manuel

dph does ship with 6.10, but only part of it - DPH is essentially split into two libraries (at the moment). the library that ships with the main distributable is labeled 'convenience without the speed', and has language extensions for nested data parallelism - but the code actually always executes sequentially! (this is not according to me, but rather to the official website for DPH). we're trying to get a working build of the other part of DPH, labeled 'speed without the convenience' - our goal here is rudimentary performance testing - which doesn't ship with the main distribution of ghc. this is the part that we're having such trouble compiling. i've tried contacting roman about this but haven't been able to get a response from him. thanks, james On Tue, Nov 25, 2008 at 4:05 PM, Don Stewart wrote:

DPH ships with GHC 6.10 -- you shouldn't need to rebuild it?
