Where are the best CPU/GPU stats

(1/2) > >>

ralph:
I'm interested in seeing some kind of sortable list featuring average workunit times, for CPU/GPU combinations, along with a summary of computer hardware cost per workunit-hour (or something like that).

It seems like the BOINC stats should allow something like that, perhaps with an additional line of two of metadata to indicate motherboard type, if it exists.

Does this exist anywhere?

Raistmer:
AFAIK no.
Time for MB task will depend from task itself (it's AR value for example), not only from hardware.
But if you will find such table it would be nice to have link :)

paxv:
It could be done, we only need a standard WU with a known amount of calculations to verify CPU or GPU processing time. And a database to compare and then we'd only have a few variables,
namely :
(optimised) BOINC version,
(optimised)Seti app version,
OS name/version,

and 
CPU brand/type/speed/cores,
cache & main memory,clock,type,
GPU brand/type/speed(s) memclock,ramtype,shaders etc,

instruction sets,
OC info...

Though some could be derived from the components it would still create a huge problem to verify results... But still... It might be usefull.
I know SETI Netherlands did a speed comparison a while ago. maybe there's still something listed.

Still no luck finding sortable SETI benchmarks by hardware/GPU/motherboard type.

I got a 30% speedup by running an optimized SETI client for the AMD x2 processor.
This took WU processing time from 2:40 (160 minutes) to just under 1:50 (110 minutes).

I then added an Nvidia GeForce 250 board, replacing the ATI card which doesn't support CUDA, with an nVidia card.  The workunits are all larger now, so I can't directly compare new and old processing times, but it's between 60 and 100% faster now.

Three questions:

1a) Is there a case style with more room for the 12v power connectors on nVidia cards?
The current card has connectors that stick up from the top, and this Antec HTPC case doesn't leave enough clearance to put the lid on.

1b) Which GPU board has power connectors that stick straight out from the board, instead of at a right angle.

2) When will there be a SETI client optimized for OpenCL - this would benefit ATI and nVidia GPU users.

3) This ECS/AMD motherboard has only one PCI express x16 slot, is there a recommended Intel core i7 motherboard that has more PCI express slots for more GPUs?  I might prefer put 4 $100 GPUs instead of a single $600 one.

Still not, AMD/ATI has no OpenCL support for GPU. Moreover, very probably their initial OpenCL GPU support will be severely limited (as current CPU  is). But they promise...

When OpenCL tools will be available for public from both card manufacturers (even nVidia has OpenCL only for closed beta group now) SETI will be ported to OpenCL.
