I alwyas thought Micorosft CPU limit was Physical Processors, not effective processors no of processors, though with Datacentre it may be different and they may be stingy ;)]


Nope, you can stack up as many CPU's as you want, the limitation is with the OS itself and the effective # of threads ("cores") it can take.

Chillerworks is indeed correct.

No Windows version supports more than 64 cores.

Unfortunately, Windows server 2008 ("Longhorn") won't change that either.

Linux is your best friend ITPC ;)


It's a shame if it's true with 2008. Especially that Intel is going to sell quad-core Xeons. So it makes 128 cores for Unisys ES7000/one.

If Linux has been mentioned...
I can run these systems on my server:
Red Hat Enterprise AS 4 for AMD64/Intel EM64T
Red Hat Enterprise AS 4 for X86
Red Hat Enterprise AS 5 for AMD64/Intel EM64T
SUSE Enterprise Server 10 for AMD64/Intel EM64T
SUSE Enterprise Server 9 for AMD64/Intel EM64T
SUSE Enterprise Server 9 for X86

All Red Hats have no limits. SUSE says that max is 128 for v10 for AMD64/EM64T.

If you have any experience, please, let me know which one is the best for BOINC/Rosetta.

FluffyChicken is correct when it comes to XP (and maybe Vista too).

XP home supports only one chip, but no limit on the number of threads (up to 64, I guess).

XP Pro supports up to two chips, but no limit on the number of threads (up to 64, I guess).


Yes,AFAIK that's an artifical limit made by MS in order to sell lower priced entry based OS's.

Yes it is indeed a shame. but that market is 99% linux based for a reason tho.
Basiclly it depends on your needs and ease of use so I guess your best shot is to consult a network manager or some other exeperienced users.
I never worked with a SuSe so Im really not familiar with it.
Ive worked with red hat before and it was rather nice and simple(yep powerful), but that was about 4 years ago, so I'm pretty sure much has changed since :)

The limit is 100 per day per host. I'm not sure why the BOINC message showed you 400. I guess I'm not positive which number is correct. Can't say I've run in to anyone that reached 100 per day without ending each one in error (which is why a limit exists by the way).

It's 100 per core per day, with upper limit 4 cores, but with updated server-code #cores is project-configurable. On web-page, you'll see the 100/day per core.

In the BOINC-client on the other hand, it's using the actual wu/day-limit for the computer, it's not per core.

So basically, both ways to display it is correct. :)

Neat! Let's see how high you can get the RAC for that machine!

If you do find yourself running into quota limits for that machine, even with your settings set for 24-hour workunits, you can take a look at this thread, where you can find how to make your workunit lenghts go longer than 24 hours.

Sorry for the language, but: FRICK'N AWESOME!!!

P.S. I would be really curious though, to see how many models that monster could crunch out per individual WU's, if set to 24hr WU run time.
