1) Message boards : Number crunching : Mac Pro, 8 cores (Message 51756)

Post:
So I bought a Mac Pro, 8 Xeon Penryn cores at 2.8ghz each.

Within a couple of weeks, I'll have crunched more for Rosetta with it than with my other computers in the past couple of years.

Am also excited about the new version of Rosetta (mini). Hopefully this will mean even better science and an easier time optimizing the software (SSEx, PS3, etc).


+1

Esp. for intel macs. All of them support SSE3 or greater. No legacy processor support holding it back.

XP Home supports 1 chip, XP Pro supports 2 chips. As far as I know, the number of cores is unlimited.

In any case, I have several XP Home machines with quad core chips running all 4 cores.

but keep in mind a normal pc wont really take much more than 3gb of memory, the rest it can't cee.. so it wont be 1024 Mb/core on a quadcore.


To be clear, the 3gb limit is with 32bit windows. 32bit linux can use the full 4gb. And of curse, any 64bit OS can use as much memory as you can physically stuff into a machine.

Because from what I have seen RH on the Mac platform does not credit enough vs
the Windows platform.


Ah. I know this to be true with the OSX/PPC. Are you seeing this with OSX/Intel too?

FYI, even windows and linux apps are under-credited to some degree too.

Still not understanding why not running the native OSX/Intel app.

Not quite sure what you meant, can you elaborate on this?

Rosetta has an OSX/Intel application. Why not use it? Why go to the trouble to run another OS on you Mac, just to use a Win or Linux app?

Done! I was just able to merge computers, that I was unable to in the past.


Me too! I successfully merged my Rosetta hosts!!

zombie67, do you have hosts participating in other projects? I do have hosts participating in CPDN, and there I can't merge hosts.. Have you got any news?

I participate in CPDN, but do not have any duplicate hosts there to merge. My guess is that they are also using a very old version of the sever SW. Bug them to upgrade.

It would really be nice if R@H upgrade the Boinc Server Software, so more hosts could be merged ...

Great news! No need to install linux on the HD of the PS3 any more. PS3GRID now has a "live" version you run off of a usb thumb drive, just like you would do with any linux live CD. This "live" thumb drive works with any other projects with PS3 apps like yoyo@home.

For what it is worth, I run two 285 Opterons (4 cores each at 2.6 GHz).

Opteron 285 is two cores each.

Core 2 spanks Opteron. In fact, just one Q6600 may be able to beat the opteron machine you describe.

I'm not sure I understand the point of this thread here. I understand why it exists on RALPH, of course. But with sufficient testing on RALPH, why is this thread needed here?

To be clear, F@H, PS3GRID, and yoyo@home applications all use the SPEs. SIMAP has a generic PPC/linux application that will run on the PS3, but it uses only the PPC/PPE controller, and has the expecte performance of a G4 Mac. Someone on SETI@home created a non-SPE app, but I haven't seen any further development with it since S@H moved to multibeam. Hydrogen@home has plans for a PS3 application, but no details or timeline.

We'll do an update in the near future.

Yes! Thanks! Don't forget to also update the "merge computer" function too.


Any news? Or perhaps an estimated timeline?

Thanks!

Post:
I've just reported those results to the Project Team to scrutenize. So I guess there's just enough transparency to track down the ummm... "funny" results reported by that host. And yes, I should think THAT would be a large factor on credit for the specific batches of tasks that had these huge claims reported.

You see that machine is claiming these models are very easy to produce. So their result would skew the average. In comparison to that, we're all having more trouble working to complete a model then benchmarks would predict, and so we're getting less credit then we would if these excessive claims weren't reported.

Wrong thread?

These are all Rosetta only machines...

If you are going to remote machines, I advise having them attached to at least three projects.

I'm not sure why other Q6600 systems aren't doing better. Most of the ones I see are below 1000.

Perhaps they are attached to multiple projects.

So a Q6600 should be able to do a bit more than half, or ~1300. And as much as ~1700 OC.


Well, there it is. It even broke 1700 RAC:
