I've started crunching couple of days ago and I've been quite surprised to see the following results with my machines per WU:

Mini 2.0 ghz (T7200) Mac OS 10.5 : 15 min 20 s
Mac Pro 2.66 Mac OS 10.5 : 11 min 29 s
Pentium IV 3 Ghz HT Win XP Pro: 11 min 44s
Dell Latitude 2 Ghz (T7200) Xp Pro 09 min 46 s

Comparing the first and last (same CPU), we have a -33% performance difference for the very same CPU under Mac OS 10.5.

Another Mac user gave similar results:
mini CD 2,16Ghz 11min 20s (100%)
mini C2D 2Ghz 15min 15s (70%)

These were posted in the macbidouille forum (French Hardmac)

Anyone with similar issues ?

That is quite disapointing at the eve of a Raid, looks like Mac Intel users are going to run with a chain on their feet...

in the last version of the application we did a lot of optimizations to the non-intel macs, so thats probably the reason you're seeing the difference in speed. we're working on re-compiling for intel macs to speed everything up.

You did? On my G5 PPC, app 1.21 is taking exactly the same time per task as app 1.13 did.

well, we updated everything non-mac i guess ;) i thought the PPC macs were optimized but i guess not. this is pretty high on our to-do list. we'd like to have macs inline with windows/linux. before the optimizations i think the macs were the fastest.

Hi Travis,

Thanks for your reply.

If you have a look at other projects, you'll see that this is definitely worth it: G5 bi-pro and Mac Pro are quite common in the top 20 crunching machines, quite amazing taking into account the Apple market share.

I do not such OS/Cpu combination in MW stats, thus IMHO, it deserves the pretty high priority on your to-do list. ;-)

It may be due to the Mac's crunching abilities....but I'm thinking it has more to do with fairness to all participants as far as urgency :)

:-)

Right but project interest and fairness to participants are not incompatible at all.

It is about combining the pleasure of participating to a scientific project and the fun (something childish, but I'm a big child eventually) of participating to a competition.

;-)))


If you're looking for volunteers to test some alpha/beta Macintel versions, do not hesitate...

well, it's also sort of personal. both my machines are macs :D dave uses one as well. we just need to dig a bit farther into xcode and get it to use the same optimization flags we used on the other versions.

Okido, in the meantime, I put all my machines (PC and Macs) 99% on MW for the Alliance Francophone Raid.

Thanks !
