Booya!!!

I just loaded folding onto my iBook 300Mhz. There are no graphics in the GUI. I was wondering if thats a video card problem? i.e. Having an unsupported video card in OS X.

Also what sort of time does it take to do one unit?
I know it will vary by process, but a general idea will help.
Thanks

Since they set up a server specifically for the Mac client, our times have become much more predictable. You can expect it to take around a day, maybe a bit less, or more if you use the iBook during the crunch time.

The missing graphics have been complained about before, but only by people using slightly older Macs. It looks like the client requires OpenGL for the graphics, if OS X OpenGL drivers have not yet been released for your graphics chip, the graphics do not appear.

This is speculation, to my knowledge the Folding project folks have not commented on this issue.

Hm...

I'll try firing up the gui version on my 333 beige G3 (It was originally a 233 Beige G3- rev 1 mobo- ATI Rage II+)

I'll see if I have graphics.

I bet you right though, and I bet I won't have graphics.

The others are right re: the graphics. As to your times, it takes my iBook 600 about 7.5 hours average, running the GUI client hidden, so I would guess you will be around 15 hours, give or take a little. (depending on RAM, cache and Motherboard speed)

bump / test......

The Graphics work in the screen saver version...oddly enough.

Does anyone know if they plan to code F@H for AltiVec?

Good question. The last I saw on their Yahoo discussion group, it seemed as they they weren't convinced that it would benefit them. However, now that they have a "closer" working relationship with Apple, there is no telling what might come of it. It would be nice. It would also draw a flock of mac users to it.

If you have a large matrix of numbers to be crunched and each element in the matrix goes thought the same process, then Alti-Vec is great. The RC5 core crunches 4 keys simultanously, that's why it's almost 4 times faster.

However projects that involve genetics don't have large matrices of numbers. Instead they use large strings of the characters G, A, T, and C. Alti-Vec won't be too handy in managing stuff like that.

Characters can easily be represented as numbers. On a computer they really are numbers.

Gene Folding is perfectly vectorizable.
Some of the bio folks just need to get together with the math folks and take some folding algorithms and make them efficient.
Then macs can kick *** in most of the DC projects.
