....wait.
so that means my 290 time for 7950 isn't bad at all?
now i know.
290 is kinda unexpected for me. We should have an edition for 7950/270x really soon.so that means my 290 time for 7950 isn't bad at all?
now i know.
i guess it's better for a 7950 to be mixed with 7970s/280x then?
There shouldn't be any correlation.280x now floating around 230-250.
with such low cpu usage would it be safe to set affinity to just 1 core so i can use the remaining cores for cpu mining?
How do we know this isn't just a clever way to sell a server farm? I'd like to see blockchain embedded proof that these users' GPUs are actually the ones mining these blocks.
yes just one card 
Time is around 210 and estimated ch/d is 1.36
Time is around 210 and estimated ch/d is 1.36 
cpuusage set to 7 but only using 7-8% of the E3 1230v3; note i used affinity mask for cores 1-7 but only 3 of those cores as showing any use.
That's for 1 card, right?We'll probably expand -cpuusage setting in a future version.

There shouldn't be any correlation. Son of a.... So I've now "found" 1 block and four chains, but no coins to date. Been running about two days now. Blarg. Some people get lucky... some people write blogs. 
Ouch... On the bright side, your 'time' value is pretty good for 7950.....wait.

Could you please stop derailing the thread, thank you.
Ok
All the versions supporting R9 290 (since Catalyst 13.11 Beta 6) are sub-par, hence each moderately complicated kernel benefits from choosing its own particular version. Miscompiles are frequent for fragments with intensive integer computations, some versions are unable to compile heavily unrolled kernels at all.
There is no official AMD GCN ISA assembler available to the public. This http://openwall.info/wiki/john/development/GCN-ISA unofficial implementation appears to be most promising, but needs work.

It seems to me that member mtrlt was on the right track but needed some help with an efficient multiple-precision arithmetic implementation.

Although I have almost no experience with OpenCL, it will not take too much time to supercharge mtrlt's code with an efficient implementation of some functions. I will have some playtime in May to mess around with the code.

You are right, his code makes perfect sense but contains several bugs, some of them are obvious, some are hard to even detect. Making a functional prototype out of it seems to be moderately hard (don't ask me how do I know), getting competitive performance even on GCN is much harder, as usual, though. Modern AMD's OpenCL compiler is unstable, unpredictable and buggy, it is no fun to play with.
Do you have any suggestions for the best OpenCL compiler version to use? ISA Assembler?
Thanks in advance
All the versions supporting R9 290 (since Catalyst 13.11 Beta 6) are essentially sub-par, and it appears benefitial to try different releases for each moderately complicated kernel individually. Miscompiles are frequent for fragments with intensive integer computations, some versions are unable to compile heavily unrolled kernels at all.

Does the wallet need be open for this to work correctly seems the miner is running but it gave error when the wallet was open?
Son of a.... So I've now "found" 1 block and four chains, but no coins to date. Been running about two days now. Blarg. Some people get lucky... some people write blogs.
Ouch... On the bright side, your 'time' value is pretty good for 7950. How are 290x improvements coming along? Eta?
I want to buy this for a couple of my cards, but if 290x improvements are coming soon, I would prefer to run it on those instead.
We're planning to make a 290x-optimized version in 1 month, but it can take a bit more time.I want to buy this for a couple of my cards, but if 290x improvements are coming soon, I would prefer to run it on those instead.
So testing on my 3x7950 rig, I finally (FINALLY!) found a block:
Great! Except, where are the coins stored? I have the client running on another system, and here's what I see:

It is good but expensive. Whether makes sense to buy it for a booty on 2X HD7950?
I don't think so. Please wait till we make a special edition for your GPU (if everything goes ok, it'll take 1-2 weeks). It won't be super efficient but it will be cheaper than its "full" (280x) counterpart.
I'm running 16 280x Cards -would love to try this out on my 4 4 Card Rigs. I also have a 4 card 7870 Rig and 4 270x rigs with 4 cards each.
Can I apply to test? Also - all of my systems run the 4770K processor - so that might also be a speed factor as opposed to alot of people who run slow processors on their GPU rigs.
Thanks please PM me! I have XPM - been mining on beeer since December.
