[ Folding ] We only need 13,000ppd more to start catching ABXzone
- Thread starter verbal
- Start date
I'll try to answer both your questions, but i'm sure someone will fill in the gaps:
Nvidia ppd for has increased slighlty with updates to CUDA in the driver updates. ATI ppd is still lagging behind. But this may change shortly as the third generation cores are due in the next few weeks/months (GPU3 / fahcore_15). This is suposedly built on more open source code and should be far more optimised (given the lenght of time they've been runnign proper WUs on GPU2), but it will depend on how the instructions are sent to the cards, CUDA's C++ handling may still make it more efficient on the nVidia cards - we will see.
My rough esitmates at ppd on cards (all depending on WU and OC), i'm sure someone will correct me on these!
gtx295 16k-19kppd
gtx285 ~8-10k ppd
gtx275 ~7-9k ppd
gtx260 ~6-8k ppd
9800gx2 ~13-15k ppd
8800gtx ~ 4.5-6.5k ppd
gts250/9800gt/8800gt ~4-6k ppd
8600 ~1.5k ppd
ATI i dont really know!

As for the Multicore clients:
These are again due for an upgrade in the near future, this may even result in a good windows smp client (the current one still sucks!)
VMware 3.0 has up to 7 core support (many problems reported setting it to 8), so it is no longer required to run multiple VMs to take advantage of a quad.
PPD is reasonable under the linux client (VM or native) e.g i'd get ~6kppd on my Core2 quad @3.7Ghz.
The BigAdv units run on an i7 in linux or a vm (using 4cores+HT for max ppd in native linux or '7' cores in a VM) will now net 25k for completion plus a time bonus, potentially netting the user ~25kppd if the complete one every 2days or so.
multiple single threaded clients generate less ppd than an smp client, roughly 25% less iirc

I presume that means my q6600 is scoring significantly too low for some reason?
And, by the way, does it score continuously (although updating only every hour/three hours) or does it score only when you complete a work unit? I presume the latter?

tbh, that just sounds plain weird! The two things that I can think of straight off would be either a driver issue or an unstable power supply.
Try using VirtualBox, you should be able to export the vmdk files directly into a new vm in VB.

Now is it just me or do the WU's come in pairs because i Have two 1888's come in @ the same time and it's bloody annoying me 
That should see you riser up the ranks nicely.
Is it running in SMP mode, or the standard Gromacs? Post up a shot of processes in task manager.

I've got 3 of the buggers at the moment
Gromacs/Amber, whatever that means, according to FahMon?
Oh yer I sucked it up and stuck all cores on, and turned the fans up/opened the window hehe!
The GPUs are supposedly not running at full core usage btw (kept artefacting after a few hours so I'm slowly reducing core usage until it stops), and CPU speed is actually 3.45GHz (speedfan thinks I have x9 multiplier, it's x8)
Cheers
looks like you're using the regular single cpu cores. You'll get better ppd with the smp client, which on windows is a bit tricky to set up. You'll get even more ppd on a linux machine or a linux vm (as a lot of the team do). The linux client is much easier to est up, but if you're a windows guy, then there's the hassle of setting up an unfamiliar OS.... although I think you can get pre-prepared appliance vms.
There's a very good guide somewhere in these forums (might be one of he stickies
)

Think this is the guide that Happy posted a few pages back good guide on how to setup a VM

The SMP GUIDE can be found here.

Cool thanks. I take it I'm looking at c.25% ppd increase? For just CPU or GPUs also? Anyway I'll look at them after my exam tomorrow
*runs from OcUK*Xeon x7350s do 4.5 - 5k ppd and an overclocked 720BE does 3 - 3.5k ppd
(irrelevant, I know... but hey!)
Anyone know if there's a reason to only use two cores per Linux VM? (as per http://www.ocforums.com/showpost.php?p=6061998&postcount=6) Rather than 4 cores one VM.
Because you only used to be able to use 2 cores in Vmware player. Now you can use 4 you can use one VM and save some RAM
Ah cool
thanks.
