True enough. Anyone wanna donate a range of intel hosts to the cause. LOL I have the P4 1.8 (mandriva), a Celeron 500 (256 Mram, win98se), and a P60 (48Mram, win98se), so anything faster would help fill out the data. LOL

So far (atleast for my computers), I get about the same credit/hour with Einstein 4.17, Rosetta, and the stock seti app (actually the stock seti app is a snidge lower). So, I'm not complaining.

So maybe the "callibration" to find fair credit numbers for the workunits was even made on an AMD system :-).

It would be interesting to have Climate Prediction figures in the comparison as well, I didn't make any systematic comparisons like Astro's but have CPDN and E@H running each on one of the cores of my Intel Mac Mini and CPDN seems to be a bit more generous.

BTW: I found the message by Bruce Allen on credit comparision (S5R1/I vs S5R2):

Note that in the past Einstein@Home has been giving out 30% too much credit compared with other projects (see BOINC cross-project credit comparison for details).

That CPND has been generous

That CPND has been generous with its cr/hr has been known for a long time. Paul D. Buck (BOINC Wiki originator) mentioned it.

But thats probably fair, I don't know anybody that has completed one of their 1000+ hr units without doing regular backups, and re-storing from backup occasionally.

Hi all,
What about CeleronD 3.22(overclocked),Celeron 2.4GHz,Pentium II 350MHz,P1 188MHz,P1 133MHz and finally 486 :-) ?

I am getting about 2.6

I am getting about 2.6 credits/hour on my 400 MHz PII running Linux in Einstein. In comparison, SETI gives me 2.2 and QMC barely 2.

RE: Hi Astro! Note there

Hi Astro!

Note there is a known issue that causes AMD K8 CPUs to perfrom ca. 30 -40 % slower under Windows (as compared to Linux and otherwise comparable Intel boxes under Windows). It's the fault of teh Microsoft compiler that will switch to a very slow code path in case the CPU doesn't support SSE2 or its a K8 from AMD.

A fix is worked on. So multiplying the claimed credit with 1.3 for the K8s will give you an estimation for the time after a fix of this problem.

I think in the official announcements for S5R2 there was a statement about S5R1 being too generous by ca. 30 % when compared to other projects, but I can't find that message at the moment.

With the patch (from this thread) applied, my AMD X2 4600+ system gets ~18 Crd/hr. For SETI using the optimized science app, I get almost 31 Crd/hr on the same system.

Seti Classic Final Total: 11446 WU.

Given that there are ~500 posts in the thread, could you possibly be a bit more specific?

The interesting part starts about here : http://einsteinathome.org/node/191381&nowrap=true#68790, with a partial solution evalving shortly after Akos' message.
