1) Message boards : Number crunching : Who hoards the wu's? (Message 25106)
Posted 14 Jan 2013 by angler
Post:
I note the other day I received a few wu's and my machine crunched them within hours of getting them and then the queue ran out. There were 15k or so wu's in progress. This number has been dropping, but extremely slowly and in no way near the speed at which it really should. Are people able to hoard wu's? Or are there just extremely slow computers doing them?

Cheers,

Paul.

yes and yes. also folks do split time with other projects and some systems are not on 24/7, may only crunch while idle or go to sleep/hibernate after a certain amt of time or report only periodically. I have a bunch of systems and many fall into each of these categories

the computation errors seems to occur more with Intel hosts, probably from the estimated cycles to complete. but those hosts probably benefited less from the latest compiles, in fact my Intel hosts show little difference between pni and gen images in terms of execution times

your SSE2 may have been short WU's to begin with, trick is to compare to your wingman.

I guess in your case you can abort the 2nd instance and someone else should get it. Believe a few others have encountered the situation recently as well.

was looking to see if my wingman had completed this result, was sort of surprised to find out the same machine had been assigned the validation.

at least the results seemed consistent :D

looks like the older Athlon linux PC I have is running sse2 now with expected completion in under 10 hrs, a vast improvement over the 30+ before

pni and sse3 variants have also been assigned for Windows PCs running AMD and Intel.

pni image seems to only run as fast as sse2 on phenom II on first observation.

Interesting, linux 6.10 host running sse3 so there seems to be no correlation between boinc host and whether or not the sse3 image gets downloaded?

One suggestion - SSE4 and SSSE3 both imply the processor is capable of SSE3/pni.
so maybe it would be easier to check for an "OR" of those flags?

pni is definitely reported on old versions with Pentium D and Phenom processors on windows.

Win 7 x64 also reports it as PNI under 8.0.28

however a wingman running Win 7 Home x64
is working under 6.10, so it seems arbitrary?

another instance of Win32 AMD running considerably faster than Linux wingman on a faster AMD. the Win32 AMD is a quad ~2.3Ghz and the faster x6 1090T should be ~3.4Ghz yet took 40% longer on 443.07

haven't gotten SSE3 units either running i5, Win7 x64 and 7.0.28 so that's not true.

http://lhcathomeclassic.cern.ch/sixtrack/workunit.php?wuid=1798048
this WU appears that I'm not using the sse3 image but kept pace with my wingman i7 (hyperthreaded I assume)

got a linux_gen unit 444.01, worked fine took about 7x longer than my wingman
but he was Intel i7 sse3. I expected to be 2-3x slower on my older AMD on a similar unit so this sounds pretty reasonable.

sounds promising, at least it'll allow me to return results within a reasonable time frame for my wingman.

my current Win32 x86 AMD is able to complete after ~20hrs http://lhcathomeclassic.cern.ch/sixtrack/workunit.php?wuid=1750589 of computing on latest results. the faster box running Linux 64 is seldom able to complete in 48 hrs.
