41) Message boards : Number crunching : Idea for Boinc..... (Message 1166544)
Posted 30 Oct 2011 by Profile -= Vyper =-
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!

I remember those times nearly gonna list my systems i've had during my life

In order:

* Sinclair ZX Spectrum 48K
* Atari 800XL
* Atari 130XE
* Amiga 500
Upgraded the Amiga with a Scsi harddrive
Upgraded the Amiga with a Motorola 68030 board and 8 MB Fast Ram
* Homebuilt PC 1, Pentium 120 which ran at 133Mhz
* Homebuilt PC 2, MMX 166 ran at 225 Mhz

* Homebuilt PC 9, Athlon 64 X2 4000+ which i ran in 5000+ speed.
* Homebuilt PC 10, Intel Core 2 E6600 which i ran in 3.2Ghz
Exchanged the CPU to Q6600
* Homebuilt PC 11, Intel Core Q9450 which i ran in 3.4Ghz
* Homebuilt PC 12, Intel I7 920 which i ran in 3.4Ghz
Exchanged the CPU to Xeon L5630

And here we are today still. This was only the main system listing which is my preliminary computer.

Posted 12 May 2011 by Profile -= Vyper =-
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?

49) Message boards : Number crunching : Cmd line to suspend (Message 1100220)
Posted 24 Apr 2011 by Profile -= Vyper =-
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.

Boinc only seems to see 60 (cores physical as virtual) cores and thus cannot adress more cores than this! Whatever change you do if that numbers show others then you would most ceratinly succeed in utilizing more cores in the system when finding that magical tweak.

Hmm

I have an idea, perhaps it's a limit in boinc to only handle 64 subprocesses and it can't load more cores by itself.

If you take a read at my blog i have a workaround that could suit the need to fully utilize that system.

Unfortunately the hosts get separate "hosts id" though they are running in the same machine but you can easily merge the numbers you get from the system to see the total RAC of that system.

Look here for the principals to run more than one boinc installation in one system.

nVidia HAS noticed.

The first s@h app if i don't recall wrong nvidia helped Berkeley in incorporating and they were quite fast with that *hrm*
Only about two years after the first CUDA 8800 GT* generation arrived late 2006 :)

P.S Hmm with that beeing said, we need some sponsors for showing the real deal of GPUs , the electricity for running those isn't cheap at all in my country. The cost is nearly 2,5 GTX 580's in price / year just powering it on for my top rig D.S

Posted 23 Feb 2011 by Profile -= Vyper =-
Well

For some reason the Cuda part of the driver and/or PhysX isn't enabled, the quickest way to fix this is to only download the newest driver from nvidias homepage and install it and you should be set to go again.
Why this has occured i don't know but this it what it seems like.
Start with that and report back if it solved your issue or not.
You could use the archived driver 197.3x to install over to maintain the highest RAC possible.

60) Message boards : Number crunching : 2 or 3 WU's On A GTX 470 (Message 1075780)
Posted 10 Feb 2011 by Profile -= Vyper =-
There is no definite answer to this one.

But we can presume this would be the most accurate, run 2 WU's if you run the card at stock clocks and if you OC your graphics card you can try to run 3 Wu's.

What you can test if you are into OC'ing is to see if PCI-E speed has a remarkable impact on crunching speed.

For instance if you run three WU's at once in a OC configuration on the 470 you would perhaps get around 23 to 24 minutes for a bunch of 0.4x AR wu's..
Then go to the bios and try to set PCI-E speed to 110 Mhz instead of 100 (Don't set it much higher than that) and see if you lower your times to perhaps 22,3 - 23,3 minutes for the same 0.4x AR wu's..

If the difference is negliable then set it back to 100 because then you've made a proof of concept test that shows that setting the PCI-E speed gives you a speed boost to the GPU operations or perhaps not.

Hope you get some ideas of direction for a better throughput.

Kind regards Vyper
