I've got a few ps_s79_... and they seem to have crunched OK

Yeah, 32bit SSSE3 Linux dropped from 22 to 9 minutes.
64bit SSSE3 runs them in 8.5 minutes compared to 18 with the stock app.
Both on Intel Q6600.
Very nice :)

Yeah, the Linux 64-bit could also have SSE2 optimizations.

Funny thing that my AMD X2 @2600 MHz now is faster than a Q6600 @3300 MHZ, 20 minutes compared to 22 minutes with Linux 32-bit, how come?

64-bit Linux is crunching fine here and does them in 18 minutes on a Q6600 @3200 MHz.

Hm, windows 0.19 don't want to download for some reason..

Yep, runs them in 00:20 on an AMD X2 32-bit compared to 00:31 with Linux opt app 0.16 for AMD

(sorry i trashed 24 units when trying 0.18c beta, downloading error)

Post:
Seems fine here with speedimic's opt Linux app but they are purged so quickly so it's hard to see the result.
Make them 10 times longer and ease the stress on the server? ;)

Well said.

I get some work now and then but not much.

I like how this project is handled and this is the only boinCidoinc project I run nowadays.

Me likes testing new versions :-)

Post:
32-bit Linux a tiny bit slower than before
64-bit Linux 20% or 10 minutes slower than v0.07 (?) but much better than 0.10

Post:
32-bit Linux is one or two minutes faster than before.
64-bit Linux takes double time.

64-bit Linux validates ok but takes double time to complete compared with 32-bit

My Linux boxen have always run at full speed for many years and there is no throttling at all.

Your "boxen" have up-to-date processors and kernel, so you should be able to type "powersave -r" from the command-line when the system is idle to check the effective CPU frequency.

Most current standard Linux set ups come with default power management that's more sophisticated than old throttling.

HTH

If an idle box can save power that's nice
Tested Fedora and Ubuntu renicing the app to 0 and there is no difference in runtimes

No I don't believe in that

What do you mean? It's either true or it isn't - I don't know which and I don't feel like checking, but there is no magic here.

True, different compilers, different results. But most importantly, Linux keeps the CPU at the lowest frequency when just running low-priority BOINC applications, whereas Windows throws the CPU at the highest frequency for them too. See more details here.

HTH

No I don't believe in that

Some WUs run extremely long time, I have aborted this one after over 18 hours:

http://milkyway.cs.rpi.edu/milkyway/result.php?resultid=57580672

Yup, same here, I have three nm_stripe_79_fr1 running for over four hours and only 45% done.
Well I don't mind if they are long, the longer the better..

Looked at my results and had 11 successful nm_stripe79_er1, 17 nm_stripe79_er2 and 2 nm_stripe82_er1. No errors seen. (Linux)

Have some old boincies in storage, 5.2.13 was nice :)
