Asteroids@home - new to me! Whose crunching it?

[GLeeM]

The old units I've received have all be re-sends: errors and aborts.

Oops! I hope they aren't any of mine

I looked at some of mine and my wingmen crunched them with SSE3 app. I don't get it.

 

[salvorhardin]

They're probably mine . I think the workunits can be crunched by either app but it's assigned and app version when it's distributed. When the sse3 app was released I updated the project to see if it would update to the newer version and start crunching with it, but it just kept crunching with whatever application was assigned to each workunit. Now running at 4.2, don't want to be falling behind

i ran a single Asteroids@Home task on my 1055T approx. one month ago (pre-SSE3 optimization), and it completed in 8,951s (~2.5 hours). ran some SSE3-optimized tasks today on the same CPU and they finished in ~2,800s (~47 minutes). its unfortunate that the 1055T won't see even more improvement when the AVX-optimized app releases, but at the same time i can't complain about my run times being only a third what they used to be on an AMD Phenom II CPU.

hmm...well now i'm confused. the task that ran for 8,951s was a v100.00 task. i've since received a mix of SSE3-optimized and non-SSE3-optimized tasks, but the non-SSE3-optimized tasks are now v101.10, and only take ~4,550s (~1.25 hours) to complete...so the SSE-optimized tasks are only twice as fast as these v101.10 non-SSE3 tasks, but three times as fast as the v100.00 non-SSE3 tasks. i'm not sure what the difference between the two non-SSE3 tasks are...

There have been 2 optimized releases.
Until early August, the application was v100.00
then came optimized v101.10
then came optimized v100.00 (abc)

I joined back in Asteroids after doing another project for a day. I got the SSE3 projects everyone is talking about now. I didn't get them until leaving the project and rejoining. I'm completing the SSE3 tasks in 37 minutes. Between 2200-2300 seconds on my FX 8350 running stock 4.0 GHz.

"No, mix of SSEx and AVX instruction is very ineffective. Especially when SSE2 instruction follow AVX instruction.

We will not release AVX version, simply because it's slower than SSE3. The final approach will be:

1. Standard app
2. Pure SSE2 app
3. SSE3 app (the fastest one)

Kyong is testing SSE2 now. I'm working on standard app now (some backports from sse3 version) as preparation step for nVidia CUDA development."

as preparation step for nVidia CUDA development.

Good news!
We can always use another GPU project

When I try to run BOINC I get an app error (0xc000007b), that's a windows error code isn't it?
I'm going to try to re-install it.

Nice to see this thread snowballing

 

[Sunny129]

yes, a quick google search associates the error code 0xc000007b with "the application was unable to start correctly." of course that could mean just about anything...but i would simply try restarting/rebooting the system first before you uninstall and reinstall BOINC.

 

[Assimilator1]

Already did that, re-install fixed it
And yea it came up with that error.

But now I get '24/08/2013 16:29:36 | Asteroids@home | Project is temporarily shut down for maintenance'

Oh well I've gotta blow the dust out the HSF anyway! After I've got around this damn video transcoding problem!......

Message from Project Admin:

"There is a maintenance being in progress, server will be stopped for a few hours. It should be working again at about 18:00 UTC.

I think a little later in the thread is posted this:

I have inspect this and it looks like AVX2 app for Intel Hasvel.

AVX2 brings new integer instructions to 256 bit AVX world which is missing in AVX. We use them in app so our AVX app must use SSE2 instructions for integers.

We use Visual studio 2010 for win builds and there is no AVX2 support. Visual studio 2012 do not support Win Vista and older OS.

I have ordered one i5-4670 in our company and I will test AVX2. If tests will be succesfull we will create download section and let users download special app with app_info.xml included.

Ten minutes per WU on Hasvel!!

from HA-SOFT, project developer/tester, in response to a user's question:

Only CUDA, no OpenCL?

I will do CUDA version for nVidia cards so I can talk about CUDA version only.

Kyong has some long term plans about OpenCL, but I can't say more.

 

[Assimilator1]

Yey got WUs now , just gotta let F@H finish it's current WU, currently @85%.

Anyone know how to stop it getting more WUs?

If you are using the version 7 client, open up FAHControl and press the "finish" button.

 

[Assimilator1]

Yes but I don't see the button, @97% now!

[edit] Nope, looked at advanced & web control, 98%

[edit2] Oh well it had already downloaded another 1 anyway, does it have any abort feature?
Running A@H now....... bloody hell it's set the temperature alarm off already! Seems to run ~4C hotter than F@H, peaking at 70C! Lol, I'd better dust out the HSF before running it properly . Running it @75% load for now.

 

[Assimilator1]

Dusted out & now down to @ 66C, 100% load, ambient 25C.
Hmm, CPU temp still quite high though.

Anyone else notice higher temps with A@H?

 

[biodoc]

Yes, I'm seeing higher temps which are probably due to SSE3 optimization?

Link to FahControl image with control buttons on top.

I only crunch FAH during the december holiday race so am a bit rusty. :\

EDIT: Maybe the control buttons are only visible in "novice mode"??

 

[Bradtech519]

We are doing real good. #7 ranking ! Good job everyone!

http://asteroidsathome.net/boinc/top_teams.php

 

[Bradtech519]

Maybe 1-2c difference since sse3. I'm at 48-50c load on my fx8350 stock.

[Assimilator1]

Arrggghh, keep running out of WUs! Gotta try to remember how to up the cache now........ done

Btw we're only no7 by RAC , we're actually no31 but we're climbing fast .

Biodoc
I haven't got all of those buttons

NWM
What's your name in this? [edit] nm, saw it's GRRO.
Btw I've still got no idea what family CPU you have , mine's a Core 2 quad.

Hmm, you've got a 53k head start!

 

[Assimilator1]

Is anyone else still struggling to get WUs?
I'm gonna have to ramp down to 50%.

This reminds of the old days of SETI lol.

I think that they are having server issues. I haven't had anything validate in about a day.

 

[Assimilator1]

I ran out of WUs last night, my cache change didn't have chance to get new WUs.
Also can't access their homepage.
