Haha, fair enough then :D

BTW, the new announcement wouldn't have something to do with nbody transitioning to GPUs, would it?

This is not THE big news; we are still finalizing details so I can't say anything more.

Wait, what? So this app is for real?

I don't mean to sound like a jerk (and MW@H is one of, if not my favorite DC project bar none), but why on earth would you bother?

Every single one of my nbody units seem to be erroring out instantly. Can't tell if its a problem on my end or MW's :(

I would hate to see the performance per watt for this, it would be excruciatingly poor. Nice to see some innovation I guess, but is it really worth anyones while running this when a gpu, let alone an x86 CPU (even an intel atom! LOL) would be hundreds of times faster and efficient than an ARM CPU?

It IS interesting from a purely technical viewpoint though

EDIT: just realized it's the 1st of April, nice one ;D

Especially if you enjoy constant frustration and arrogant admins who don't care about the people doing their work for them. Check out the forum before joining.


I'm going to have to call you on that cheap shot. The guys at GPUGRID have been great in the forum. I've been running GPUGRID plus MW for a few months in the same machine and have had very few problems. Normally, most project issues are the fault of the driver or BOINC, but there's nothing a rollback can't do.

The science they are doing is great, and it is a good community to be with.

Perhaps you can be more constructive by actually stating what kind of frustrations you were having? Following their instructions verbatim is the best way to go, including the swan_sync = 0 switch if you're in windows.

Anyway just my 2c

Theoretically this week I could put out a Linux ATI/OpenCL application for testing. It's not yet as fast as the Windows ATI one, but it's something.


This OpenCL client wouldn't be the elusive n-body app for GPU's would it?
