This is the best thing that have happened in years!
Really good work and good move to keep this Project alive and sound.

Perhaps all work could get to their ends without timing out and requiring resends all the time like Before!

I'm so thrilled and thankful!

Kind regards Vyper

Matt!

Check the motherboard to see what the brand is and model no., perhaps it's a watchdog timer in bios that locks the machine (fails to reset) when the context/interrupt switching is high.
Todays virtualization Technologies stresses that to the max.
If so tweak all buffers and NIC's to reduce the thing mentioned above and if it "lasts" longer then you're on the right track!

Kind regards Vyper

Maybe a openvpn server and a pdu is something to invest in so you could reboot stuff from example a android phone. :)

Perhaps should persuade Slavac to set it up on the gpuug site.

You always want a safe connection to a pdu so you could restart the server while eating the turkey :D

Happy thanksgiving over there.

26) Message boards : Number crunching : Average RAC for GTX 670/680.? (Message 1294940)
Posted 13 Oct 2012 by Profile -= Vyper =-Project donor
Hi there.

One of my machines have a single non OCed 670 so i'll post some numbers.
Running 2 WU's in parallell = 0.5

Lower AR shorties takes around 130 seconds / WU gives around 25 credits. (AR = 4.319562)
Higher AR shorties takes around 148 seconds / WU gives around 28 credits. (AR = 2.716736)
Upper MID AR takes around 272 seconds / WU, gives around 50 credits. (AR = 1.122237)
MID AR takes around 580 seconds / WU, gives around 118 credits. (AR = 0.420551)
Lower MID AR takes around 856 seconds / WU, gives around 165 credits. (AR = 0.238529)

So that equals to:
86400/130 * 2 * 25 = 33230 credits
86400/148 * 2 * 28 = 32691 credits
86400/272 * 2 * 50 = 31764 credits
86400/580 * 2 * 118 = 35155 credits
86400/856 * 2 * 165 = 33308 credits.

If you add them all 33230+32691+31764+35155+33308 and divides by 5 = Median of 33283 credits and if you take into consideration that main distribution is shorties then you need to slighly lower the RAC..

There you have it then.
A single GTX670 stock clock gives around 33100 in RAC by itself 24/7/365.
Running setiathome enhanced x41z, Cuda 4.20

Mbcuda.cfg =
processpriority = abovenormal
pfblockspersm = 15
pfperiodsperlaunch = 200

Running on a 2600K @ 4GHZ non HT.

Kind regards Vyper

Hey

Please jump in and navigate a few dudes which have a website which they call a "Analogue Website".

You can watch a video, fax them messages, like, Beer (after 6 PM) etc etc.
It's quite fun actually.

30) Message boards : Number crunching : Can I select which WU/project goes to which GPU? (Message 1190289)
Posted 31 Jan 2012 by Profile -= Vyper =-Project donor
there is always the (Vyper style) option to go to old drivers


Lol! I'm refered to as Vyper style!
Wth! It's the only way i can fully load those beasts on that particular platform and god know why really.
As long as it works it works because i don't think that the speed benefits would be that much better on pre-fermi cards anyway.

It's simply as running the platform on what makes it works the best and for me it is to use the good old 190.38 driver with a quad cpu feeding octo gpu with no cpu tasks congesting the cpu pipes to free it for the GPU's..

Simply as that :)

31) Message boards : Number crunching : Idea for Boinc..... (Message 1166637)
Posted 31 Oct 2011 by Profile -= Vyper =-Project donor
But the client can't send a compressed request file unless it is known that the server can accept compressed request files. BOINC != SETI.


Ofcourse!

This needs to be implemented as follows.

1. Those who "design" BOINC needs to get this information and apply this on their application.
2. They need to test that the solution works and figure out a futureproof design of the implementation.
3. When they're done, they can release a new "alpha" server version to be installed followed by an "alpha" BOINC client.
4. Seti would update their "Boinc" seti installation on the beta site and request people to try the latest "alpha" boinc client installation.
5. Tests would be performed for perhaps two weeks to see that it works as intended or they would report it to the boinc developers.
6. We pretend that there were errors and a new version has been released. Seti updates beta site and people are encouraged to try the new alpha Boinc client again.
7. Things worked as intended for a week without any hickup. Seti starts to design a implementation protocol and schedule to implement this on seti main.
8. One week has passed with the design and is about to be implemented on the next Tuesday outage. People are beeing informed about the upgrade and could be encouraged to download a new Boinc client and two days before this Tuesday outage occurs the new Boinc alpha client which hopefully hasn't have had any sort of "side effect" is beeing upgraded to be a "latest stable" version.
9. Seti is monitoring their sides and perhaps notices an "ooops" and noticed that the server process which monitor and processes the in/out flow of status files is beeing "capped" by a high load and starts to fall behind.
10. They implement four virtual servers (or instances, scripts on four different loaded machines) , two for each drawer which by filtering is checking for differnt files thus the handling is divided by four different processes guarding those in/out directories and notices that it would now work even if they manage to have a weeks outage that could and will occur in the future by Murphys Law.
11. Things are smooth but they need to trim the servers so they wouldn't drop connections if things aren't as sleek as it should behave.
12. They are an a roll within a week and all major flaws has been ironed out, the patch has been implemented and they never again looked back on uncompressed datafiles and the bandwidth/transactions/requests/resends wouldn't be as capped as it were two months earlier.


There you have it, a small miniproject of a implementation basis and schedule for Boinc infrastructure!
It wasn't that hard was it! ;-)

Kind regards Vyper

P.S All this are based on pure speculations from my PoV D.S

Posted 30 Oct 2011 by Profile -= Vyper =-Project donor
I just wanted to correct myself about the statement of the approach.
Actually the boinc client which send units to the servers could be named in a way in the filename so the servers know which boinc id which is sending compressed files.
In that way the servers automatically know which client is using compression just to list the filename for example:

_Idname_filename.zip
_3050453_xxxxxxx.zip

In that way it's easy implemented that boinc at the other end is responding to compressed files as well so the servers can tag 3050453 computer id with compressed files to be sent and recieved.
And if everybody thinks of security and manipulation there is no issue because pure uncompressed files is not secure either at all so there is no problem with that approach either.

And i endorse my opinion of compressing the data files before they are sent!
Cpu's are getting faster and faster, ram cheaper and cheaper. Just look on the latest three servers that the s@h community has sponsored.

Every server has 96GB of ram!

That's alot.

I just tried compressing sched_request and it was 510KB and the file became 17Kb in size.
The stress involved on the cpu's on s@h would increase ofcourse but it could be implemented soo simple, the upload and download servers do their work as usual but they can have a script that watches the up/download queues and every minute a ls *.zip process can be run to pipe the zip files to a decompressor and then delete the file afterwards.
The routine for this doesn't need to be run at the up/download servers, another server internally could just "poll" the directorys and handle the compressing actually freeing that duty from up/download servers.
Ofcourse you need to have some "how much space is there left" in the batch script but this could be implemented as well with a "no biggie" in the boinc infrastructure.
So could we implement Marks and my ideas then the bandwidth would drop tremendously keeping more bandwidth available for true workunit transfers as it should!

(edit)And you need to have a routine that polls what version of Boinc you are using so that this would be plausible. So that the scripts can watch for that version number so it could be supported otherwise leave it uncompressed as usual..(/edit)

Thoughts and ideas ppl?

I ask everyone to spread this word and for the cause of it join up for a petition against crime and violence.

So please, send this to everyone you know and you think you know via msn, icq, mail or even a postcard to let the world know that this act amongst other violence against innocent civilians throughout the world is a horrendous act beyond all comprehension..

Silent prayer go out to Norway!

My heart goes out to my fellow scandinavian friends whom has been a victim of serious attack!
91 kids has been killed in a maniac shooting and the bomb at the ministrybuilding.
This is utterly insane and i sincerly hope that all familys and relatives to all poor children that has now past away get the help and support needed through this horendous trauma.

My condolences to you all!

You wanna argue with me? Go ahead......and see who comes in first.
I have been at this far longer than most.

Stats don't lie.

Neither do kitties....LOL.


Hey!

Why so upset and try to persuade people to argue?!
You're totally right! I've noticed it too.
Better having the equipment running at 25% overclocked stable nonstop 24/7 than having it running unstable at 30% overclock.
The power usage is so much higher to an extent that it's not worth it powerbill wise.
Man if i'd even think about it 10 years ago that it wouldn't be worth overclocking extremely in the future due to the fact that power is costing that much more now i would've considered myself crazy! But here we are and running totaly full bore is not worth it wattage wise and stable wise!

Posted 12 May 2011 by Profile -= Vyper =-Project donor
I'm for the moment in touch with an ISP to try to get prices to install fibre in a apartment where i live.

The price that the property owner needs to pay is about 250 brittish pounds / apartment... There are eight apartments where i live. So that equals 250 * 8 in installation fee for diggin, fibre, cat 6 wires to every apartment etc.

Then maximum bandwidth we can buy is 1000 Mbit..
Prices is for Bredband (broadband) 1000 Down 500-1000/ Up 60-100 Mbit/s 799:- SEK
That would equal about 75 brittish pounds a month for that speed or 126 dollars a month..

Is that good or bad countrywise?

Kind regards Vyper
40) Message boards : Number crunching : Cmd line to suspend (Message 1100220)
Posted 24 Apr 2011 by Profile -= Vyper =-Project donor
This are my lines of doing it.
A while back when boincmgr.exe and boinc.exe couldn't handle projects with a lots of download/uploads and workunits at the same time i couldn't even get boincmanager to do what i wanted because of the constant wait window appearing.

That's why i needed a cmdline to suspend it.

@ECHO OFF
cd "c:\program files\boinc"
boinccmd --host localhost --passwd xxxxxxx --project http://setiathome.berkeley.edu suspend
EXIT

Take care.

Kind regards Vyper
