Looking for Multi CPU and Multi GPU projects...

Alright, I will take that challenge. Oh, wait...the 5870 is in the shop! How about I will try to hang with you off of my CPU credits until the replacement arrives??? LOL!

OK, your on!

[DrPop]

OK, your on!

Nice! Nothing like a good ole SETI.USA rivalry. I'm running in "crippled mode" but let's see what I can put up.
@Beer and Sping - you guys in too?

How's the credit for nvidia vs amd? It's been a while since I crunched at Collatz.

Sticking my foot in the water to test. Going to run collatz on my nvidia card to see what I get. Time to chase some MM's instead of maximizing my credit anyways.

Slicker can give us the real answer, but last time I checked, ATI/AMD was better credit. It's been a while since I tried an Nvidia card on Collatz though.
It's actually decent credit on NVIDIA, just not what PG was giving, so we all crunched that. However, now that PG dropped its credit, and DiRT seems to have issues half the time, Collatz just might be one of the better bets for both GPUs now. I'm sure some of the guys can give us some comments as well.

Here is what I'm getting on 2 cards:

Run time   CPU time       Credit        Application

1,398.44   1,396.29       3,055.05	collatz v2.09 (ati13ati)  AMD 6970
2,248.85   357.18         3,125.08	collatz v2.03 (cuda23)  GTX 590

OK, so someone correct me if I'm wrong, but the GTX 590 should be at least double the HD 6970, and it's not (credit / sec) so that means it still slightly (maybe 30% or so?) favors ATI/AMD GPUs for credit...

I think the real question is, how does that credit / sec compare to what your GTX 590 can do on PG or DiRT?

The HD 6970 could certainly do much better on Moo! if you also dedicate 1 CPU core along with that. But, with DNETC gone, of course that's not the point - the point was to crunch a little Collatz and support Slicker.

It looks like the ATI is one GPU and the 590 is 2... that's one WHOPPING ATI card LOL..

ATI:

• Up to 880MHz Engine Clock
• 2GB GDDR5 Memory
• 1375MHz Memory Clock (5.5 Gbps GDDR5)
• 176 GB/s memory bandwidth (maximum)
• 2.7 TFLOPs Single Precision compute power
• 683 GFLOPs Double Precision compute power
• TeraScale 3 Unified Processing Architecture
  
  • 1536 Stream Processors (1536:96:32)
  • 96 Texture Units
  • 128 Z/Stencil ROP Units
  • 32 Color ROP Units
  • Dual geometry and dual rendering engines
  
  

NVIDIA 590
PU Engine Specs:1024CUDA Cores
607Graphics Clock (MHz)
1215Processor Clock (MHz)
77.7Texture Fill Rate (billion/sec)
Memory Specs:
1707 MHzMemory Clock
3072MB (1536MB per GPU)Standard Memory Config (1.5MB per GPU)

Note for the 590 the Glfop rating is for BOTH GPUs.. So each do only about 1244... and thats just single precision.. double would be about 1/2 that. The ati cards wins out because it looks like it has more processors (1536:96:32) vs the NV card (1024:128:96) and runs 200Mhz faster. But one thing to consider.. far more boinc projects seem to support Nvidia over ATi, but I'm sure that will change. Where the 590 will outshine this ATI card is in DP math.. that single ati GPU can only do about 600Gflops of DP math... on the 590, each gpu can do about 500-600Gflops... and most boinc apps can use DP.. and more and more are *requiring* DP cards or they just won't run.

I don't like ATI cards, but that's for gaming. I don't like the way it renders textures, and handle FX. To me, graphics on an ATI card look a bit "fuzzy" and it drives me up a wall.. but Id have no bias against them for crunching It looks like ATI FAR FAR wins out in crunching vs nvidia with this card and higher models. I'm sure nv will respond soon with something that trumps ATI.. then ATI will trump NV.. it's a never ending cycle

In closing.. for SP Math crunching that ATI card wins HANDS DOWN.. for DP cruching.. it can't come close to the 590.. as each 590 can do 500-600gflops of DP math

Nvidia is better if you are crunching Distr or PG.

Run time	CPU time	Credit	        Application

721.03	        63.96	        2,411.00	PPS (Sieve) v1.39 (cuda23)  PG GTX 590
= 3.34 credits/sec

1,398.44         1,396.29       3,055.05	collatz v2.09 (ati13ati)  AMD 6970

I could get more credits crunching PG or Distr, but I'm putting in some time since the project is run by our own Slicker Plus, I want to get my MM up for this project.

The cards are an EVGA Classified GTX 590 running stock at 630/1260/1728 (core/shader/memory). The other card is an HIS Radeon HD 6970 IceQ. I don't know the stock settings for it though.
