- longer deadline for the Py wsus. Only 23 hours is too little time, especially when the predicted runtime is two days
Or maybe just a better prediction of the runtime, which appears to be around 2.5hrs for an average system, 4.5hrs for a more basic one.

The deadlines are 2 days. If it takes more than 2 days to do 8 hours of work (the default runtime) then Rosetta just isn't the project for you.


I have no problem with the project, just the python vbox app. Virtual box seems to be a real pain in the ass, IMHO.

WTF is going on here. I've never had a SPAM popup from BOINC before. Intentional or not, it is the definition of SPAM. Seems like the only likely solution is to detach Rosetta.


No, because it's a one off by accident, you're overreacting. Once you delete the message, you won't see it again.

That is not true, people have managed to crunch e.g. MilkyWay@Home using their Android GPU by means of the alternate platform. The Boinc Client can handle Mali GPUs at the very least:

I just rebuilt the windows version with SSE2 and see a minor improvement (1.6%) from a really quick test. I'll push it out to ralph soon. Thanks for the helpful input and suggestions for optimizations etc.


As SSE2 has been around since the Pentium 4 (2001), can we expect new versions with SSE3 (2004), SSSE3 (2006), SSE4 (2006), AES (2008), AVX (2008),
F16C (AMD: 2009/Intel: 2001), and/or FMA instructions (2011-2013) at Ralph soon too?

That's not true! On https://boinc.bakerlab.org/rosetta/home.php Rosetta gives links to the following stats sites, linking directly to the users own stats -if the links are not dead yet-:

    BOINCstats
    BOINC Statistics for the WORLD!

All the original poster asks for is to include that page as can be found on the FreeDC site. For me that would be http://stats.free-dc.org/stats.php?page=userbycpid&cpid=76d20230028d9ceee3a1aa52fcf14dd4

Over 95% of Boinc users are cpu only users, that only leaves 5% of us that use our gpu's to crunch with.


Are you refering to the 316,738 people that once registered with Rosetta, or the 39,735 that are presently active? (source: nl.boincstats.com)

Or are you refering to the 2,186,474 that once registered with BOINC vs the 322,644 that are presently active? (source: nl.boincstats.com)

Considering the CP-GPU systems are quite recent, a percentage of 5% from 316,738 (or from 2,186,474) suddenly increases seven- to tenfold IF all those systems are still active. In which case we are suddenly discussing a whopping 35 or even 50% of the active systems.
CAN you quote the percentages for the 39,735 and/or the 322,644?

I personally could care less about using a graphics card for... graphics.

Personally, I only care about its ability to crunch for science, as a gp-gpu.

I don't know the answer for certain, but suspect it is "No.": Can "ATI's leading card" handle double precision floating point as well as Fermi?

Still couldn't beat ATI's leading card. Although, I don't know whether it's easier to code for an Nvidia video card or an ATI one.



Actually the ATI/AMD leading cards of the last years, the HD 5970 the last years and now the HD 6990 can run rings around the best nVidia card when it comes to double precision.

The GTX 295, nVidia's leading card of days gone by, could do 1788 GFlops single precision against a very meagre 149 GFlop double precision.
The GTX 590, nVidia's present leading card, does 2486 GFlops singkle precision against a still meagre 311 GFLop double precision.
The Quadro 6000 -nVidia's less-limited leading professional card- gives 1030 Gflops single precision, but deliveres a modest 515 GFLop double precision.

And ATI/AMD?
The HD 5970 deliveres 4640 GFlop single precision and does 928 GFlop double precision.
The HD 6990 deliveres 5099 GFlop single precision and does 1275 GFlop double precision.

I do know the answer for certain, knowing it is "YES": Can "ATI's leading card" handle double precision floating point as well as Fermi?

A project must spend its money wisely or it will run out, to put money into something that they already KNOW will not benefit them, they really did do some research into it already, is not cost effective and just plain silly!


Do you guys ever discuss things with other projects? Have you seen the increase in output of the projects using GPU applications? I was doing around 2k of credit points a day on the various projects using only CPUs. Now, with 3 GPUs -not the strongest by any means- I am doing 100-200k a day. That is a hunderdfold increase in productivity. If you want to go on ingnoring the strengths of the new generation of GPUs that's up to you, but you are certainly not on the way of making much progress within your alloted budget.

You can also make a smaller application for the GPU to use it efficiently.

That was the point of my post, yes you can, BUT it won't do as much work in the time that a cpu can! You would have to do 3 or 4 times as many units to do the same amount of work as the cpu units do now, and there goes your time savings by using the gpu!

They REALLY HAVE thought this out and we REALLY ARE doing it the best way for now.


There are lots of people with a HD 5970, which offers 5 TFlop of computing power, and crunches WUs up to 20-25 times faster than CPU applications. The new HD 6990 wil even offer 6 TFlop, and I can get a HD 5970 for a mere 350 Euro, so how about cost effective? The HD 6990 will cost around 500 Euro and will also attract BOINC entusiasts. If you look into other project statistics you will encounter Fermi-based Tesla stations and real heavy Quadro's. Some people/institutes really can afford them, why not make use of them?

P.S. A HD 5970 has 3200 Stream processors and 2 Gb of RAM. The HD 6990 will have 3820 stream processors, and 4 Gb of RAM.

My soldering are not good enough to get my Radeon 5450 up to 2 gigs of ram (haha), and i don't think anyone else here would be willing to give it a shot.


A HD 5450 is, sorry to say, a pretty crappy card to begin with. I think you should have a poll and ask what cards people working at Rosetta have in their rigs (perhaps you do not even need to given the information the projecty already has). Me myself I have three rigs with GPUs, one with a GTX 260, a HD 4770 and a HD 3850 and I can not even keep up with those who are advancing in the ranks. My next GPU will be either a HD 5850 or a GTX 560 and as much RAM on it as budget permits.

Projects like GPUGrid, PrimeGrid, MilkyWay, Collatz, Einstein, DNETC, Seti, etc. are using the GPU with very much effect and the majority of the people working on those projects use pretty advanced GPUs (I see them passing me in the scores) and 2 Gb of memory (or more) will pretty soon be standard on high-end GPUs.

Post:
yes you are correct that Rosetta does not have a gpu app. It is because the current app is waaaaay too big to fit onto a gpu, it can easily take more than 2 gig of memory, and if you start swapping memory on a gpu all efficiency is lost. They have tested it and said when/if it becomes a viable alternative they will introduce one.


Is that true? How can it be then that I can run Rosetta on machines with only 1 Gb of memory? Isn't it true that there are GPUs on the market with up to 6 Gb of memory (nVidia Quadro 6000, Tesla stations). You can also make a smaller application for the GPU to use it efficiently.

Sure it would be practical. Why wouldn't it. Web sites are remotely hosted all the time.

Maybe because it's part of the BOINC server suite and puts things like the user's RAC on their posts? I don't know how closely the two are tied together...


The forum is the forum. Stats are some else entirely. It is common practice in IT-world to have your feedback about an application on a physically different machine (so not another virtual machine hosted on the same physical server..), at least in the companies I worked for (IBM, AT&T)

Hi!

I was wondering, whether it is possible to use GPU (3D card) to crunch Rosetta@home packets, is it? At least, GPUs have very much computing power...

Just to complete the thought - the problem is that GPUs only have single precision floating point capability. The Boinc projects usually need at least double precision floating point. So it's a no-go for GPU crunching for now.


Well, at some point in time you were right, but any nVidia card with compute capability 1.3 or higher will have double precision floating point capability,
meaning any card from GTX260 or better. It is also present on the ATI Radeon HD 5970, the HD 5800 Series (5830, 5850 and 5870), the HD 4800 Series, the Mobile Radeon HD 4800 Series, the HD 3800 Series, FirePro V8800, V8700 and V7800 Series and AMD FireStream 9200 Series GPUs. So the double-precision floating point argument falls flat.
