Message 1865030 - Posted: 1 May 2017, 15:16:23 UTC

I recently had a PC tech find/add a water cooler to my Xeon machine. While I am running a mixed load that is mostly Seti at home with some Seti Beta and World Community Grid its mostly Seti at home.

I also have an Intel 5-2400 with about the same cpu speed.

My Intel5 seems to be averaging maybe 2 1/2 hours per WU at 100% cpu processing and my Xeon is still running 4-5 hours per WU at 100% cpu processing.

Is this more likely a difference in data or is my elderly Xeon that much less efficient than my somewhat newer Intel5-2400?

Yes, the gpu cards for both machines are running at about the same speeds.

Thanks,

Are both machines running the same CPU app flavor? I see noticeable big differences in CPU processing times between the SSE2 and AVX versions of the r3330 app.

I see quite a difference too between my i5/i7 processors
i5-4460 _ 2.9 _ 4/4 __ AVX __ 29.4 GFlops __ Running 4/4C ___ 59 Tasks/Day
i7-3930 _ 3.2 _ 6/12 _ AVX __ 23.3 GFlops __Running 7/12T _ 97 Tasks/Day
i7 - 960 _ 3.2 _ 4/8 __ SSSE3 _ 14.3 GFlops__ Running 4/8T ___ 31 Tasks/Day

My i5 definitely has better processing times than my (all be it older) higher clocked i7's (even if they are not threaded).
But my i7-3930 masks up for it in threads running.

The Xeon W3565 is a rebadged i7-965. So it isn't that surprising the i5-2400 would be faster. The i7-860 I have is a bit faster that the i7-900 of the same speed. Despite only have two memory channels vs the i7-900's three. Each generation, or half generation drive the performance up bit by bit.

Intel have steadily been improving their CPUs single threaded performance over the years, as well as reducing power consumption.

An excellent question. It appears that both of my cpu's are running the Seti version 8.05 at this time on both production and beta testing. I run "stock" Bonic/Seti under Windows 7 Pro/Home.

Since I posted the question I have looked at the range of estimated processing times and they run for the 5+ hours down to the maybe an hour and half. So it is very possible that this is a data-driven issue too.

The other confounding issue is I am running my hyper threading on my Xeon. Up to this point I hadn't thought it would make any differences. Unlike some of the very early generation hyper threading that I have experienced, this HT seemed to be pretty symmetrical on processing speeds.

Sometime I might try running the Xeon w/o HT and take a look.

Brent,
Where did you get the above information? I would love to have an external indicator of the "tasks/day" rather than my horse-back guesses.

Thank you,

I get Tasks/day from a program called BonicTasks, it's on the projects tab.
GFlops comes from the Application Details on the Computer info page of Seti web pages.

I too run BOINCTasks as my general purpose BOINC monitor. Has lots of features and makes it very easy to manipulate and monitor multiple machines from a single location.

Please note that the tasks/day or /week in BoincTasks is downloaded tasks, not crunched tasks. http://efmer.com/b/boinctasks_settings#projects
