Enough ..................

I will express my view on a project I love whether you like it or not

I will crunch on the project when I can get a card that will perform to the cost performance ratio that I can afford. I haved mo0veed to an ATI card due to reason connected with my work, and theyt nothing to do with you.

I want to restart the crunching that i did for over year for a very personal reason.

I will express my views - politely - on a card that i am interested in buying if it performs the way i want it to perform.

You dont like - tough - and I'll thank you to keep your crass opinions of my "shame" to yourself, I am not interested ........................

After 35 years of software development running teams the size of which you could only dream about, its about time you zipped it. You dont own GPU Grid, so keep your personal opinions of others to yourself.

If that earns me a ban - fine - because that was the most appauling crass and arrogent comment i have seen on a BOINC board for a very long time.

GOODBYE............................

Wow! Maybe he's going to f@h. BTW I had to go there too with my 8800GT 256MB which didn't have enough RAM for GPUGRID.net the 9400 IGP likes GPUGRID.net though, 3 days a week ;-)

f@h took over the PS3's, Ati runs better there, & if I was miffed with GPUGRID.net I'd go there too. But Nvidia is the way & Fermi is the future of Nvidia. That GPUGRID.net is the 8th in combined credits & the 5th in RAC & f@h gets more work done then the combined BOINC community, says something too. Is the future bright, or very bleak?

The future will be brighter when also ATI works nicely.

Performance for a reference molecular system (DHFR):
GTX275 9.0 ms/step (cuda3.0)
GTX275 8.5 ms/step (cuda2.2)
GTX470 7.1 ms/step (cuda3.0)
GTX480 5.9 ms/step (cuda3.0)

Running temperature of about 92 degrees for all of them.

PS. Your RAC is still at Zero and yet you still keep banging on. Have you no shame?

A RAC of zero only means that the participant has not been able to work on a particular project for some time. I was, i think, number 8 or 9 on the project some time back ... but I am falling because I am slowly replacing my Nvidia cards with ATIs because of the price performance and the power drawn for said same ... when I replace my last three Nvidia cards my RAC also will fall to zero ... not because I don't believe int the project, but because the project is not supporting me ...

Now, I don't think Zydor blames GPU Grid, and neither do I, for not having an ATI application already ... but ... he did do 1M CS and that is nothing to disrespect. And, if and when GPU Grid does have a working ATI application I am sure that if he can he, like I, will be putting GPU Grid back in our project rotations ...

The point Zy was trying to make is that even after optimization it is unlikely that the speed improvement is going to be high enough to justify the cost of the card or the power it draws. Perhaps he did not say it artfully, perhaps you misunderstood ... but just because someone has a RAC of zero does not mean that we should not give them fair hearing ...

More sharply to the point there does not even seem to be a doubling of performance between the GTX295 and its putative replacement. Generally, one expects that the next generation GPU doubles or triples the performance of the prior generation of cards. For example, the preliminary numbers I have for the 4870 vs 5870 cards I have is that the 5870s are twice as productive, much quieter, and don't draw that much more power ...

Sorry guys, we are still testing.
Hopefully tomorrow we can get out the new beta.

Fermi's still too rich for me, this is just a hobby for myself. I don't plan to use any newly developed anti-psychotic medicine. But others might & God knows how many (drug) experimenting youthes, war vets, & traumatized civilians in war zones will need them, on top of everybody else that's sick or stressed.

But appart from not gaining enough performance/price out of Fermi, it's great work on the part of GPUGRID.net, BOINC, & Nvidia to get as much out of the GPU's as possible.

I can't prove this appart from that I got much more work done on my 8800GT 256MB on Linux then on Windows, but I'm about to take my two GTX260 on my Windows PC with an RAC of 46-59K & switch it over to the Linux PC using one GTX260 with a RAC of 27-29K (which also stops due to lacking system RAM which is 2GB which I also will switch with the 4GB Windows PC). In 2 weeks to a month, I'll know for sure if it indeed is true that you get much more done on Linux VS Windows.

Someone told me that this was not the case, & that GPUGRID.net would get as much work done on a Windows or Linux, but I beg to differ & will soon know if it's true. If this is the case, people should know, if it's credits they want & GPUGRID.net wants WU completed faster.

my GTX480 is itching to go... it's hungry for some wu with a little chianti :D

Hopefully tomorrow we can get out the new beta.

We will be here to support you whenever you are ready!

Just to point out the GTX295 is a 2 GPU card and the GTX480 is a Single GPU Card. Therefore on a GPU to GPU comparison the performance did increase by quiet a bit and the drivers/software is not optimized for the 480 yet where the 200 series cards have had a long time to get optimized.

This is correct, but misleading too in that the 4870 and 5870 are also single "CPU" cards as well ... based on the numbers that I recall people telling me about the Fermi it either barely matches or lags behind the 5870 and that is not the best from ATI ... and it is far older ...

Generally speaking, when Nvidia comes out with a card that is supposed to compete with ATI (and the converse) one expects that the new card will have 1.5 to 3 times the performance of the rival;s top-of-the-line card... that is not the case here... there is a valid point, almost, that the compiler is not ready, but, that misses the point that it SHOULD have been ready and working and stable .. and it isn't ...

Yes the ATI world has issues as noted by GDF in another thread tonight that they may have figured out where the issue is ... but, part of that is the learning curve of coming up with the understanding of the tools and architecture of a different system ... they know CUDA, now they have to learn Stream ... the same, but different ... we know it can be done, witness MW, Collatz and now DNETC ... soon GPU Grid? we can but hope ...

part of that is the learning curve of coming up with the understanding of the tools and architecture

Exactly what is the case with Fermi, it has brought major changes to the architecture and how data is processed

acemdbeta6.23 cuda3 for windows should work on Fermi.
We could not test on Windows as the cards are on Linux for now.

Except Fermi should have been backwards compatible, and does not appear to be so ...

Processed two beta WU with gtx480 = OK

# 9 - 8 min 0 secs
# 10 - 7 min 29 secs

ftpd - looks good! That is on WinXP correct?
I think my card downclocked (clockrate reports as 0.81) and is not waking up properly as I am throwing errors on all WUs.
It will be another 4 hours before I get home and get things stightened out.
I will post back as soon as I can.

Thanks - Steve

Processed another two beta-WU with GTX480 on Windows-XP-pr 06.10.50 (boinc-mgr).

# 16 - 7 min 0 secs
# 50 - 7 min 51 secs

Eight other jobs being processed also the same time!

I have no remote-control with my GTX470, so monday.

We have added a way such that you can control the use of CPU.
If you set the environment variable in Windows:

SWAN_SYNC=0

then it will use a full CPU core and be around 20/30% faster.
Unset it and it goes back to standard low cpu usage.

so to get try out the new beta for cuda 3.0 all we have to do is to select ACEMD beta is gpugrid preferences?

yes. and need to have a cuda3 driver.
