I don't remember which version it was fixed in.

>11.6 and <=11.11

I know it is fixed in 11.11. As pointed out above you can even use 12.1 just make sure to install Runtime/SDK FIRST and then do CUSTOM SETUP and the uncheck OpenCL Runtime. Once installed 2.6 is a pain to get rid of. That is why I suggested 11.11. It is a version I know has no 100% CPU bug and it doesn't have 2.6 so no chance of accidentally installing it.

OK, I pretty sure this is ancient history, but here goes anyway.

I've been using Windoze XP with Catalyst 11.6 with a 5830 and 5770 and had low CPU utilization with that combination. I went back to my Win7 install where I was using 10.9 to get low CPU utilization prior to CGMiner 2.0. I updated this Win7 to Catalyst 11.6 and now have 100% CPU utilization. I had thought Catalyst 11.6 had low CPU utilization across all platforms?

Any thoughts? Or is this just the way it works with Windoze 7?

IIRC was a lot later than 11.6 before 100% bug was solved in Windows.

Catalyst 11.6 was before the bug was introduced, which is why I was using it.

Why not use 11.11?

I don't know why not, was the 100% CPU utilization for multiple GPU's fixed in that version? When I was messing with this installation before I had a terrible time get later Catalyst versions installed and functioning at all which was why I was using 10.7 and 10.9 at that time to begin with.
Thanks,
Sam

Why not use 12.1? As long as you don't install the SDK runtime that comes with it, it's working 100% with my 5850's.

I'm trying to use the 2.1 SDK for the 5xxx and 2.6 for the 6xxx. Everything works fine using the 2.6 sdk, but it obviously isnt efficient for the 5xxx series.
Phoenix 2.0 lets me use the setup I want, but it lacks lots of features.

I also tried making cgminer use bins compiled for 2.1 while using the 2.6 sdk but it just recompiles them again. The ideal would be making --gpu-platform a per device option, something like --gpu-platform 0,0,1

You can't.

Why do you want to use 2.6? It is junk for 5x and 6x series. Only reason to use 2.6 is if you have 7x series card.

2.1 is slightly better w/ 5x series but only with low memclock (and it is small). Both 5x & 6x work well with 2.4 & 2.5 so that is the simplest answer.

Anyone can now build Cgminer on Windows.

http://pastebin.com/3pzivj32

I spent a lot of time documenting and testing the documentation step by step on both Windows 7 and Windows XP. Shouldn't take more than 30 min to set up the build environment.

Thanks for taking the time to write this! Wink

This is not OK.

I know it'll compile fine without CPU mining, but I want to do some testing with it enabled... I want to see how Anubis handles it. If it's more trouble to get it working than it's worth, I'll forget about supporting CPUs in Anubis.

The code looks OK, and digging into the Makefile, it's OK too. I can't work out why it doesn't work :/

If you remove the --enable-cpumining you added it will work fine in windows.
Yes even without the ".exe" showing in that line I'd know that is a windows CPU mining link error.

I'm trying to compile cgminer for windows with CPU mining enabled, but I can't get it to link when I specify -msse2.
It seems that sha256_xmm.o isn't being included.
I'm getting the following error:

Code:

  CCLD   cgminer.exe
cgminer-sha256_sse2_i386.o:sha256_sse2_i386.c:(.text+0x155): undefined reference
 to `@CalcSha256_x86@12'
cgminer-sha256_sse2_i386.o:sha256_sse2_i386.c:(.text+0x16a): undefined reference
 to `@CalcSha256_x86@12'
collect2: ld returned 1 exit status

without -msse2 it compiles fine, but of course, without the SSE2 optimised code.

Any help to kick this into action???

You have to edit the code to fix that

CPU mining isn't supported.

Is there a way to set the OpenCL platform per card? Cgminer keeps crashing with a mixed 5xxx and 6xxx rig.

I'm not sure as to why it is crashing on you. I have a rig that has 3 5870's and 1 6970, and it runs just fine. Cgminer also automatically generates .bin's for each type of card (Caymen and Cypress).

Anyway, right out of the freaking manual (README)...

Q: I have multiple SDKs installed, can I choose which one it uses?
A: Run cgminer with the -n option and it will list all the platforms currently
installed. Then you can tell cgminer which platform to use with --gpu-platform.

--kernel|-k Override kernel to use (diablo, poclbm, phatk or diakgcn) - one value or comma separated

I am using 2.5 SDK for 3 5870's and 1 6970 (960/170 for all cards). I am getting 428 Mh/s on the 6970, and 442 Mh/s on the 5870's. Now if your 5xxx cards are not cypress then I guess you would want a lower version of the SDK. I let Cgminer create it's own .bin's (phatk).

You could use the -d option to force Cgminer to create a .bin for each type of card and then maybe use the -k option using comma's to specify more than one. I have never had to do any of that funky stuff so I really cannot help you with mixed SDK's.

Is there a way to get an email notification when GPU goes into SICK or DEAD state?

If not, can the APIs be used to query stats from cgminer. If possible, we could write cgminer-watchdog
to monitor the critical stats and notify you via email or sms.

That's what I'm writing at the moment ... ... but it will allow you to check many different things ...

Yeah it doesn't supply numbers that can be calculated directly - that would be a waste.

It's Accepted / Getworks ( * 100)

However, remember that the number is not very useful - it is just how many shares you found per getwork.
RollNTime allows that to be up to 500% with cgminer.

And pools with higher difficulty shares (like p2pool) or frequent LP (like merge mining alt-chain with much lower difficulty) can have an efficiency that is much lower even when everything is optimal. Really efficiency only matters as a pool op. Deepbit collectively finds ~700 shares per second. That is a lot of getworks. Even a modest improvement in efficiency reduces load but even that is marginal because peak load will still happen at an LP even with 500% efficiency.

I think a stat like the following would be a more useful metric (and prevent continually obsession w/ efficiency):

Effectiveness = accepted / worked
Effectiveness = accepted / (accepted + rejected + stale share + hardware failure)

Having a high effectiveness (no it isn't a stat in cgminer) is more important than a high efficiency.
