I am by no means a programmer so I ask this what does the new openCL 1.2 mean for mining? Are we going to notice improvements?


No.

I finally got a 5870 to mess around with, and, yeah, the "best" memory setting on that is diff than the 5830. 

At 1000/395, it gets 440mhash, at 1000/310, 448mhash, etc.

1/3rd core speed is considered the rule. So, in your case, 1000/333.

Me?

spiccioli posted this:"This fact that is not possibile to tell exactly what was found and when is a big problem, IMHO, which could stop miners from switching to p2pool."

Here: https://bitcointalk.org/index.php?topic=18313.msg741069#msg741069

If you come from a pool (I'm mining since may last year), you're used to a pool page where you find mined blocks, your payout and so on.

Here you need to grep logs and I was grepping them when I found that old blocks get re-logged as new, and as such my payouts were "wrong".

This has been fixed yesterday.

I'm not stating that p2pool is not correct, but that it is just "difficult" to prove it is Smiley

And I'm here because I like p2pool and I've never mined on deepbit.

spiccioli.

Troll less kthx.

Well since you find it appropriate to slander me with heresay, I will do the same.

P4man is actively persuing underage boys in Pattaya, I found it on google. It must be true because I think it is.

Get of your high horse, your fat ass is hurting its back.

After much discussion with the guy from gpumax, it seems to have been a slight bug in his pool software.

In other news, I found a bug in DM completely unrelated to gpumax's bug.

Today was productive.

Good to hear. Have you updated your downloads for your recent updates? For us Windows users?

The zip is always up to date, but I haven't changed anything in the past 11 days.

1 BTC to the first person to produce a FPGA farm running in a freezer.

1 BTC to the first person to produce pictures of their BFL Single with screenshots of it running.

1BTC to the mod that moved this thread to off-topic. Wait, thats me! Everyone give me 1BTC! Wink

If I recall correctly, you were going to ban me for 'trolling' a hundred and thirty pages into this thread. No dice.

Diablo had to move this to off topic because he was going to get banned for trolling/being off topic. Many of his posts got deleted.  :/


However since its a speculation thread being in off-topic is fine with me. Kept the BFL support trolls from bitching.

Nope, I didn't post in this thread at all. I really don't give a damn about BFL either way.

You must have some memory problems. You really don't recall threatening to ban me and goat telling you to suck his big black cock?

No, I remember recommending goat for a ban, you, not so much.

anyone having problems using diablo with gpumax.com ?   

syptoms:
  start.  works OK.  hashrate good.
  during:  start to get connection issues reported by diablo, but it reconnects and works.
  after a while:  the connection issues increase to the point that no shares are accepted.  but it reports a full hashrate.

fix:  stop and start diablo


I thought gpumax was a scam?

apparently it is the Long Polling that is causing it with gpumax..  can I turn off LP with diablo?


No. Tell gpumax to fix their software, no other pool is having this issue.

LOL, fix our software.  hehehehe cause all the other mining clients have issues right?  Cheesy

So other clients are having problems too?

Nope, just your miner. Sad

In this case, I think you mean "Nope, just Java." I really doubt Java has a bug in it's http client implementation, but you're welcome to track it down.

"-v 2 -w 128" results in the best performance, but also about 15% hw errors on my 6970.

Current snapshot: accept: 79 | reject: 2 | hw error: 11

Question: What exactly does this hw error mean?

It means your hardware or drivers may not be functioning correctly. Are you overclocking?


Yes. Slightly. Strange ... I don't get this hw errors with cgminer (for the exact same Mh/s).


Ive never verified if cgminer's hw error detection works.

Looks like a new heatsink. If they have any sense, the board is now mounted sideways, with the top and bottom fan working to together to blow air over the heatsink in the direction of the grooves. If the bottom fan is mounted to blow against the underside of the PCB, then, well, I cant imagine anyone being that stupid.

Diablo I have 3 7970's let me know if you need testing done.  Right now I am using Diablo no flags getting 680MHash/s 1144core/685mem.

Don't need external testing. The community donated enough that I can go buy a 7970 of my own now (thanks everyone!), but my 5850 testing just isn't done yet. I think after this current round of optimization hunting I'll finally switch.

Done stage 1:

Old kernel:
-v 1 sdk 2.6 = 883 ops 13 registers, 2.1 = 803 ops 17 registers
-v 2 sdk 2.6 = 1503 ops 21 registers, 2.1 = 1362 ops 21 registers

2.6 is 10% slower than 2.1.

New kernel:
-v 1 sdk 2.6 = 886 ops 23 registers, 887 ops 21 registers
-v 2 sdk 2.6 = 1395 39 registers, 2.1 = 1396 ops 36 registers

2.6 is tied with 2.1.

New vs old:
-v 1 =~ 0% faster 2.6, 10% slower 2.1, 2.6 is 30% away from minimum target of 681 ops
-v 2 =~ 8% faster 2.6, 2% slower 2.1, 2.6 is 2% away from minimum target of 1362 ops

If I committed this right now, 2.1 users could switch to 2.6 and not see a real difference in speed.

Now I begin stage 2: optimum ALU clause packing and register use reduction.

Edit: Somehow I got the new numbers wrong, lets try that again.

After looking at the ops generated in the .isa output, I'm clearly starting to force 2.6 to act more like the 2.1 results, so I seem to be getting somewhere. The hard part is going to be ordering instructions to properly saturate ALU clauses on vliw5 and GCN both.

Wouldn't it be easier and more efficient just to have a separate kernel for GCN? It's a totally different architecture so it would make sense to, right?

Nope, that makes no sense. Its still the same compiler, and OpenCL is a generic language meant for wildly different hardware. This kernel runs on everything from x86 to ARM to Sparc to POWER and PPC to Cell SPUs to Intel GPUs (if/when Intel actually fixes their drivers) to Nvidia to even certain DSPs.

A compiler is free to completely ignore the specific ordering of instructions I am using in the kernel and optimize it correctly for it's target hardware. AMD's doesn't, and takes significant hinting from the code to allow developers to influence the output. This is arguably both right and wrong, given how much code effects/is effected by bandwidth usage and latency and other things.

The difference between 2.6 and 2.1 is that 2.6 is tuned differently, and 2.6 allows much more hinting from the kernel layout. The compiler could freely reorder everything safely to give full performance, its just difficult on complex hardware like this; 2.1 went farther into this than 2.6 does.

I'm slightly surprised I actually need to do this, however, because AMD uses LLVM in their compiler, which is very good at SSA tree optimizations. Arguably, its rather good at what I'm doing by hand. Wink
