Just hit 8 million

Just hit 690 million myself...LOL.

But, it's all relative to what you do.

Nicely done, Zombu2.

Many meows.

Sweet jesus

you gotta tell me how to optimise my nvidia gpu's so i can crank out more WU's

Well, first you have to understand that I run 9 rigs. 8 are crunch only, so I can get away with some things that would cripple a daily driver.
First of all, you have to run the Lunatics apps.
These are basic, and some will argue about how much they are different than the stock apps, because much has been given by the optimizing crew to the project and not held back.

There are still some CPU apps, I believe, that are faster than the stock apps for whatever reason.

I run 20 something GPUs....all nvidia. This project, by choice or not, was helped along, as I recall, by some help from some nvidia insiders relating to Cuda. That help has long since been abandoned, but the original coding still lives.

Jason would be more of one to ask about why nvidia does so well here, but these days he sometimes gets to speaking in such technaleze that even I cannot understand it.

No offense, dear Jason.

Ah aright yeah i run lunatics apps and i just have a couple machines (most of em are salvaged hehe) but i got a poweredge r900 coming that has some slots free and i hope i can get 4 or 5 960's in it with a riser cable to get from 8x to 16x ports

YaY for ebay where you sometimes grab stuff for dirt cheap

No 980Tis?

No 980Tis?

No, just a few kindly donated 980s.

He knows who he is.

"Freedom is just Chaos, with better lighting." Alan Dean Foster

heh i only got 2 980 superclocked in my main machine which i have turned into a cruncher since i haven t used it for a while
Im so stuck on my chromebook i don't use anything else really
And i try to Salvage more machines i can put up to crunch .Getting the GPU's for it might be a problem though so they prolly run without till i can get more one by one.
just got a 960 yesterday which i put in a salvaged 1st gen i7

I don't understand why ppl throw perfectly fine machines away just because the OS is hosed and infected

LoL, none taken :D Yeah I have become a bit lazier with decoding the technobabble over the years, just because there're plenty of people to chip in, in some cases, and sometimes I found no simple way to present the information ( or in some cases organise it into proper words, lol)

Could be part ageing, part mad scientist kicking in I suppose.

In the case of nVidia GPUs doing better here relative to on other projects, for multi beam part is the optimisation of the Cuda libraries, another that we don't really use much double precision at all (which is knobbled except on the highest end dedicated compute models), and of course the odd couple of my own techniques, grown from research, thrown in (some of which raistmer adapted for OpenCL use too).

I've looked at some limited portions of other project Cuda sources, and they tend to be mostly devoid of some key optimisations, and/or depend on double precision a lot more. Recent gradual moves, having had some help from Petri33 with some streaming, are pointing towards ways to capture and automate these techniques more, so that they'll scale to next generation hardware better. That would be probably too costly or disruptive for some projects, since often it means throwing out large portions of code that works and starting again.

@jason_gee

how many wu's can the 900 series cards do at the same time without overloading the card and slowing everything down ?

Depends on the system feeding them, and the app+settings. Best efficiency would be in the region of 2 to 4 MBs, which will change. At least two are needed to hide serial CPU portions of processing, and driver latencies (waits)

The trick is to add enough tasks at once to just peak power demand, with the tradeoff of extra tasks creating system contention. Compare to the approach that doesn't work well, of attempting to use up VRAM.

As Apps further mature, the optimal # of tasks will likely reduce toward a probably ideal of 2, and optionally use more resources for those 2 instances.

More than 2 instances at the moment, is solely due to the app needing to catch up with the hardware.

well that explains why one WU does not use up the whole card
thnx for the explanation

FWIW there are other more sophisticated methods that can automate this process, but by nature come in future applications and supporting tools. The general gist is if you can balance these things by hand, using some sort of logic and tools, then there is a way to replicate that. How far the Boinc infrastructure can be stretched is another matter.

Greetings,

@Jason & Zombu2: This discussion is off-topic for this thread. Please take it elsewhere. Thank you. :)

Keep on BOINCing...! :)

The kitties now have 691 million kibblestones.
Should not be too long now, and they shall be able to meow about hitting seven hundred million.

And that is a bit more than your average can of kibble!

Be careful, catapulting to that many cobblestones could make you catatonic and that would catastrophic.

anyways I want to categorically express my thanks and mention most of us will never come close to catching you.

Now that I beat that category to death, time to go..lol
