Re: New codebase testing 0.B version

Also I've heard IvanG's say his ighashgpu only supports 8 cards as well. It's not true, actually. I haven't heard about systems with >8 GPUs so I have no idea will ighashgpu works with them or not. But there no hard limit of 8 GPUs in source code, AFAIR I used value like 32, so if CUDA layer will r...

Re: Multi Vender GPU rendering

I guess cost of this device (for +4 PCI-E) will be higher than cost of motherboard + case + PSU. As it always happens with non-standard solutions.

Re: New codebase testing 0.B version

Yeah, it finally works.

Now there is an other subproblem -- as system config is GTX260+GTS250 it'll nice to have thread_n = 192 for first GPU and thread_n = 128 for second one ;).

Could you confirm if it works with -gpu_mask 1 and -gpu_mask 2 ? Yes, it works separately. Could you send me barswf.log when it crashes? It doesn't crash in fact, it's locks up with heart beating.

Still problems with hybrid systems (i.e. GT200 + G92 GPUs at the same time).

Re: One more GPU hash cracker

If ighashgpu reports "Found N CAL device(s)" then CAL .dlls presents somewhere. For 64-bit system check out the /windows/syswow64 path as well or make whole disk search for "aticalrt.dll".

Re: Alienware M17x - SLI GTX280m + 9400, only one GPU running

I guess it's only possible with nVidia's GPUs as they in fact can work without monitor attached if PhysX mode selected. While ATI GPUs always requires monitor (and I'm trying to use 4770+4850 setup with Win7). I doubt it'll possible to use 8400 as main GPU and extend desktop to 4870.

Re: Alienware M17x - SLI GTX280m + 9400, only one GPU running

Actually it's better to ask nVidia directly or atleast use their CUDA forum because it's not just password cracking related problem, it's CUDA layer itself cannot recognize 2nd GPU. I think there won't be any problems with Windows XP (because of different driver model) but if installing XP isn't an ...

Re: OpenCL news

Yes, it's very unlikely that OpenCL code will be better than CAL/IL code. There was Brook+ built on CAL/IL layer, now Brook+ replaced by OpenCL but it's still built on CAL/IL layer. It's like for CPUs -- we can write in asm (CAL/IL) or use C (OpenCL). If we're good in asm then asm code will always b...

I guess I need to increase block size for 5870. Unfortunately algorithm used makes it not as easy thing as it looks.
Actually I'd prefer to use bigger blocks even for 4850 but with 5870 it became mandatory.

Re: HD 5870

5770 will be exactly the same (for hash cracking) as 4890 -- 800SP @ 850Mhz. 5750 as 720SP @ 700Mhz = 4850. But it's RV870, so better architecture anyway ;).

Re: HD 5870

drewy, thanks for the tests. Results very close to expected though a bit lower. 5870 must be (0.85*1600 / 0.75*640) = 2.83(3) times faster than 4770, so it's should be 2680M for single MD5 & 821M for SHA1. Your SHA1 test runs for less than a second, so result isn't that accurate (it actually differs...

Re: HD 5870

The only report I've got so far is for HD5850. It isn't direct information from HD5850 owner though, so errors possible.

For SHA1 5850 shows 690M (for comparison, it's 290M on 4770), so it's even better than I was expected. However system is pretty unstable, drivers aren't ready at all.

Re: How high can you get

So which one is better? Don't get me wrong :). If you want to do hash cracking only , ATI Radeons, no doubts, best choice. But if you don't wanna stuck with hash cracking only then you should consider nVidia's GPU's even if their peak performance lower than ATI's ones. That's my point. There is nea...

Re: How high can you get

Anyway Radeon HD 5870s are way better than water cooled GeForce GTX 295s. It's theoretically (no GPGPU tests with 5870s were done yet) better than GTX 295 for hash cracking if you know how to program ATI hardware . I'd prefer to correct sentence in such way :). If you want professional system for d...

Haven't tried nVidia's OpenCL by my own but have read that it's slower than CUDA. Not a surprise actually, compatibility costs some resources.

4xGTX295 is a maximum. BIOS/drivers limits GPUs number to 8, also don't forget about cooling system which takes 2 slots (actually there is water cooling for GTX295 which 1 slot only but I never seen such systems even on inet photos).
