SETI@Home Wow!-Event 2018

[lane42]

I was just comparing his Titan to my 1080ti. Mine can't do 58 seconds , but
I know what your saying. iam guessing the cuda 9.2 app. also helps pascal gpu's not just
volta. The only down side for now is he get's a lot of inconclusive results, over 600.

 

[StefanR5R]

His latest 100 valid tasks have 52 seconds average runtime. Either he dialed down, or more likely, a former lucky streak of unusually quick WUs is now over.

While browsing the setiathome forum, I saw someone stating that the high FP64 performance of Titan V isn't of use in Seti@home, even with customized code. I forgot in which thread I read this... Edit: link

 

[ericlp]

Even astropulse are hard to come by. Apparently, they are prefered over SoG... But, haven't seen any run by my system in a long time. Tho, I don't always look at the logs.

 

[lane42]

I saw this, Seti doesn't use the FP64 performance of the Tesla's or Quadros
Now 52 seconds is still pretty good, but not for 3ooo dollars. My 1080ti is at 99 seconds
and I have it in a 1x slot, one day ill put it in the x16 slot, to many gpu's to move around

@lane42, earlier this year I looked at the bus bandwidth usage of 1080Ti at SETI@home:

Here are measurements of SETI@Home's PCIe bus utilization, taken from 3x GTX 1080Ti in PCIe v3 x16/ x16/ x8 slots, obtained with nvidia-smi with 1 second reporting period, running for over an hour on Windows and on Linux, respectively.

The numbers are: average / 90%-quantile / peak.
RX = PCIe reception, TX = PCIe transmission

Windows 7 Pro 64bit, Nvidia driver 387.92, SETI@home v8 8.22 opencl_nvidia_SoG

RX: 920 / 1,400 / 1,800 MB/s
TX: 160 / 220 / 520 MB/s​

Linux Mint 64bit, Nvidia driver 384.111, setiathome_v8 8.01 cuda90

RX: 340 / 520 / 1,400 MB/s
TX: 80 / 110 / 2,100 MB/s​

I measured on a triple GPU system, but numbers are per GPU.

My peak numbers may be a bit uncertain because of the 1 s reporting interval; but I believe the 90 percentiles to be a good indicator for a performance threshold of the bus after which it doesn't affect the application performance much anymore.

PCIe v2 1x allows for 500 MB/s rx and tx each. It's 985 MB/s on PCIe v3 x1.

Thanks for the info Stefan.
Wish I was half as smart as some of you guys

@Pokey .....I don't see you yet on the team page. https://www.seti-germany.de/Wow/stats_team.php?lang=en&team=30191

Last year's result.

We had some tussles with l'AF, BOINC_Italy, and Planet_3DNow! along the race and then some RKN member(s) dropped their 35 days worth of bunker in last day and suddenly they jumped right behind us.

Is this really just an individual event? If TeAm stats are significant here, I should enter right away.

It is both. Glad to have you along for the ride if you so decide.

 

[Orange Kid]

So I have been able to get multiple Boinc instances going...…,but the extra's aren't finding my GPU. Any clues as to why? Something I need to do?
Using windows and added the cc_config.xml to each, but nothing. Added the info from the coproc_info.xml in the cc_config as that seems to not do it on it's own..nothing either way
Confused

 

[StefanR5R]

I never had to do anything special when I added client instances on my Win 7 or Linux GPU hosts. Specifically, I never put anything GPU related into cc_config.xml.

I am still undecided myself how I will manage Maintenance Tuesday during the Wow!-Event.

I decided not to bother. I will either be switching everything off (it will be hot enough next Tuesday at least), or I will be away folding some proteins for the day.

 

[crashtech]

The SETI site is down, is there a way to pull my SETI User ID # out of BOINC somewhere?

Edit: Also, does it matter which astrological sign I enter under?

Check if any of your clients has "sched_reply_setiathome.berkeley.edu.xml" in its boinc data directory. You will find <userid>...</userid> near the top.

Those who registered for last year's Wow! Event (or before), can get the ID from the user URLs in the old user list:
https://www.seti-germany.de/Wow/stats_team.php?year=2017&team=30191

However, I wonder if the registration works at all while the project server is AWOL.

Edit,
last year, late registrations ( = after the start) were possible. I guess this year too.

Edit: Also, does it matter which astrological sign I enter under?

You may pick any. It could be the one under which the neighbor's dog was born, for example.

 

[crashtech]

I'll have to wait until the site is back up.

 

[TennesseeTony]

Thanks for the info Stefan.

I wish I was half as smart as some of you "wish you were half as smart as" guys are!!!

Lunatics app for "The Search" can be found here: http://lunatics.kwsn.info/ As to how to successfully USE that app.....uhm.....dunno for sure, but I do know it makes a huge difference, a positive difference....

 

[TennesseeTony]

Well crap, last update was 18+ months ago.....so we all good, yeah? (from last year?)?

 

[TennesseeTony]

Grrrr. No CPU tasks yet, only GPU. All my settings are to run CPU/GPU of all sorts, but nothing (other than GPU) so far..........

 

[ao_ika_red]

For windows: target folder is ProgramData > BOINC >projects > setiathome.berkeley.edu
AVX customapp is only useful for SandyBridge CPU onwards (Intel) and SteamRoller, Excavator, and RyZen CPUs (AMD).

Well crap, last update was 18+ months ago.....so we all good, yeah? (from last year?)?

Lunatic's 0.45 beta 6 installer is quite old but the standalone installer is updated recently but I don't see any significant performance gain so it's not a big problem and if we compare it to stock app, the older custom app is still significantly faster.

It's picking up after usual Tuesday's maintenance day.

[StefanR5R]

I am not totally up to date, so take this with a grain of salt:
Lunatics for CPU applications (on most CPUs),
Arkayn for GPU applications (Nvidia at least).

 

[lane42]

The race starts soon, Good luck to all.
Looks like the group to beat is Taurus, but you never know.

 

[ao_ika_red]

It's started!
Good luck everyone. May your surroundings cooperate nicely.

 

[Kiska]

It's started!
Good luck everyone. May your surroundings cooperate nicely.

Mine didn't
This happened while I tried to bunker:

My UPS understandably unhappy with the situation

 

[Ken g6]

It's started!
Good luck everyone. May your surroundings cooperate nicely.

Mine didn't either. I saw the start of the race, but my internet went down before I could flush anything.

 

[TennesseeTony]

Good Heavens, Kiska! I take it that should be around 240V, instead of 400V?!?!?
