A good week for the team :) , but a poor one for me :(

For some oddity the PC does the Amber WU's OK, but most Gromacs crash. :mad: The PC, an Athlon XP3500+ isn't even clocked :( Ho hum, maybe it's time for a Conroe :D
Click to expand...
I'd be looking at the RAM then maybe

what messages do you get - or does the whole system just crash?

edit: actually what are your temps like? Gromacs uses SSE but Amber does not use any optimisations
try running StressCPU which uses part of the Gromacs code and see if that replicates the problem for you

From the High Performance FAQ - here

Which GPUs will be supported? We have not made any final decisions on this issue. However, our software will likely require the very latest GPUs from ATI (especially now that the newest ATI GPUs support 32 bit floating point operations). Previous work of ours used NVIDIA GPUs as well, but we have now concentrated on ATI GPU's as they allow for significant performance increases for FAH over NVIDIA's GPU's (at least at the current generation). Our GPU cluster has 25 1900XT's and 25 1900 XTX's. We find a considerable performance increase of 1900XT's even over 1800XT's, due to the architectural differences between the R580 and R520 GPU's. Our code will run on R520's, but considerably more slowly than R580. We're very much looking forward to trying out R600's.
Click to expand...

Other than that and the information you've already posted there is only really the specualtion in the GPU client / core issues forum

I haven't checked it out since my 9800Pro is going to be no good at all :o :p

From the sounds of it the client will be available to all since that section of the forum is also open


edit: Joe if you do go pimping please remember this is still in testing - you could do more harm than good getting a load of people running newly released clients

Thats old news, the quote from the press release i just posted was released in the last couple of days and they obviously haven't had time to update the faq yet.

Edit: The press release was made today.

yes and the fact that they don't expect to be using this generation NVidia chipsets is still relevant :p

That's a bit strange - I would have thought that cards like the X1800XT and X1600XT would work, especially since the X1900GT is listed...
Click to expand...
It's mainly about the processor on the card. The card names are very misleading, as a high number card doesn't mean a powerful processor (as far as FAH is concerned). All the 1900 class cards have the R580 processor. None of the others do. That's the deciding factor right now.

Joe42 said:
So its 100% X1900 series only?
Click to expand...
at the moment yes - though I'm not sure what controls there will be on the client, maybe it'll just interrogate the card/drivers and only run if it finds what it's after

it should be interesting to see what happens - I can see myself having a new rig near the end of this year and then a fridge full of PS3's early next year :p
 
MGP said:
Maybe that points to a memory fault somewhere?
Click to expand...
yes almost certainly it's memory related - usually if you are seeing NaN errors they can be remedied by backing off the memory timings a little
that would explain why upping the voltage has helped before as it has made the memory just stable enough for what you needed it to do at the time

you can probably keep the actual ram bus speed as it is - just slacken off the "tCAS-tRCD-tRP-tRAS" timings a little and then test

download and run CPU-Z first of all to establish what settings your RAM is currently working with and if there are any recommended settings programed in to the chips in the SPD section
 
nice find there Joe :)

how it works at the moment is that projects are benchmarked on a test rig and then the points are calculated so that particular machine gets the same PPD no matter what - currently I think this is a P4 2.8GHz with SSE2 disabled and not making use of HT either
bonus points are then added onto this score for WUs with large download/upload sizes or which use a lot more memory than average

I don't really want to guess how the multiplier will actually work but essentially WUs processed on a GPU will be worth a lot less than the same WUs processed on a CPU - we'll have to see how this works before breaking the bank filling any spare PCI-E slots I guess :p


edit: just found myself looking for suitable cards in the members market only to find hornytoe has just put an offer in on one - I had to work quite hard not to post saying I'd take it at asking :D
I'll be waiting to not only hear how the points will work but also if the amount/type of GFX RAM makes a difference, I only have the one PCI-E slot so need to get it right first time :p

More official news from the front:

Vijay Pande said:
The GPU beta launch will be on Monday Oct 2 in the afternoon (Pacific time). We have been doing extensive testing and, while all the bugs aren't worked out (this is a beta relase after all), there are no show stoppers so far and it's a good time to put this into a bigger release.

Just some heads up for people to keep in mind:

o The GPU code requires specific drivers and system software, so this will be a much more complex install than before (another reason for this being a beta release). Be prepared to potentially update your ATI driver version and/or Direct X version.

o At launch, we will only support X1900 class GPU's (X1900XT, X1900XTX, X1950, X1900GT), as they are the only GPUs which give reasonable performance with FAH. More GPU support will be forthcoming, starting with other ATI GPU's (most likely the X1800 and X1650), but we have no ETA on their support.

o People have been curious about the nature of the core in the GPU client. The GPU Gromacs core isn't a port of Gromacs, but rather we've taken key elements from Gromacs we need and enhanced them based on the unique capabities of GPU's. Thus, it's really a new and different core on the inside, but with wrapped Gromacs on the outside; the new core will be called Core_10. For example, Core_10 WU's can't correctly be run on non-GPU cores and vice versa (and thus it is impossible to run GPU WU's on non-GPU systems and vice versa). This enables some new and exciting science, but it's important to be clear that this isn't just a port. This is very similar to the inclusion of Gromacs in 2003 when FAH only ran Tinker. Gromacs' functionality is a subset of Tinker's, but Gromacs runs 20x to 30x faster than Tinker (for the parts we use Gromacs for). Since Gromacs wasn't a complete substitute for Tinker, we still use Tinker for certain key calculations. Similarly, the GPU core is faster than Gromacs, but on a limited (and somewhat augmented/altered) subset of Gromacs' capabilities.

We'll be giving the full scoop on Monday, but I wanted to try to give people some early warning so they know what to expect on Monday. This is definitely a BETA RELEASE, so don't expect something very polished. Also, we're preparing the final FAQ and HOWTO material and we will give more info as it makes sense to release it. I've even broken my own rules by releasing the info above, but I thought it was important as I want people who are interested in testing the beta to be prepared for all of what will be needed (which is unfortunately quite a bit, considering the need for driver updates, etc) to run the GPU client.

More info on Monday (and sorry, if you post questions below, I most likely won't answer until Monday -- sorry).

Thank you for the information.

I understand the need for some limitations to your ability to speak about items that are not official yet: If for no other reason, that changes can occur that invalidate the information. That being said, I'm a big believer, that more information sooner is better, if for no other reason than it makes for better planning.
Click to expand...

You've hit the nail on the head -- we sometimes need to hold back info as things are potentially changing very quickly, but I do want to give donors as much info as we can as early as we can.

I feel very strongly that we've got the best donor community in distributed computing and we owe it to you to do what we can to better help you help us!

Hmm... I was left off the single machine crunchers list this week - should have been in 12th... you no love me no more? :( :p

ooooops :p
fixed it now - sorry about that :D


that and the Tiffy's section are the two bits that rely on me to manually check through the stats so mistakes aren't hard to make, I'll get myself down to specsavers I think :p
