cgminer 2.3.2 is out with a new poclbm kernel I've been bashing with a mallet for a week to try and extract some more out of it, and I hit my target which is 720 MHash at 1200/1050+5% clocks intensity 11 with 12.3 amd drivers.  Grin
10102  Bitcoin / Mining software (miners) / Re: CGMINER GPU FPGA overclock monitor fanspeed GCN RPC linux/windows/osx 2.3.1 on: March 31, 2012, 05:11:39 AM
New version: 2.3.2 March 31 2012
Despite the huge changelog, there should be little risk in updating, with extra features and enhancements that don't affect the internals dramatically which is why the version number is still 2.3.x

Human readable changes:
Better BFL support.
Support for Icarus devices
Better hashrate calculator
Massive rewrite of poclbm kernel for fastest hashrate yet on 2.6 SDKs.
Minor updates to diablo kernel.
Updated diapolo kernel.
Attempt to get ADL stats again if they stop working.
Fanspeed starts at 50% now instead of 85% in auto mode.
Extra RPC API features.
Discarded stale counter won't rise if stales are force submitted.
Display the beginning of the new block in verbose mode in the logs.
Fixed dual GPU device fancontrol.
Monitor app started with -m should be terminated on cgminer exit.

Full changelog:
- Damping small changes in hashrate so dramatically has the tendency to always
make the hashrate underread so go back to gentle damping instead.
- Revert the crossover of variables from Vals to W in poclbm kernel now that
Vals are the first declared variables so they're used more frequently.
- Vals variables appearing first in the array in poclbm is faster.
- Change the preferred vector width to 1 for Tahiti only, not all poclbm
kernels.
- Use a time constant 0.63 for when large changes in hashrate are detected to
damp change in case the large change is an aliasing artefact instead of a real
chang
- Only increment stale counter if the detected stales are discarded.
- Attempt to re-initialise ADL should a device that previously reported fanspeed
stops reporting it.
- Move the ADL setup and clearing to separate functions and provide a reinit_adl
function to be used when adl fails while running.
- Use slightly more damping on the decay time function in the never-ending quest
to smooth off the hashmeter.
- Set the starting fanspeed to a safe and fairly neutral 50% when autofan is
enabled.
- Provide locking around updates of cgpu hashrates as well to prevent multiple
threads accessing data fields on the same device.
- Display the beginning of the new block in verbose mode in the logs.
- Reinstate old diablo kernel variable ordering from 120222, adding only goffset
and vector size hint. The massive variable ordering change only helped one SDK
on
- Change the version number on the correct kernels.
- api.c devicecode/osinfo incorrectly swapped for json
- Add extensive instructions on how to make a native windows build.
- Update version numbers of poclbm and diablo kernels as their APIs have also
changed.
- Use global offset parameter to diablo and poclbm kernel ONLY for 1 vector
kernels.
- Use poclbm preferentially on Tahiti now regardless of SDK.
- Remove unused constant passed to poclbm.
- Clean up use of macros in poclbm and use bitselect everywhere possible.
- Add vector type hint to diablo kernel.
- Add worksize and vector attribute hints to the poclbm kernel.
- Spaces for non-aligned variables in poclbm.
- More tidying of poclbm.
- Swap Vals and W variables where they can overlap in poclbm.
- More tidying of poclbm.
- Tidy up first half of poclbm.
- Clean up use of any() by diablo and poclbm kernels.
- Minor variable symmetry changes in poclbm.
- Put additions on separate lines for consistency in poclbm.
- Consolidate last use of W11 into Vals4 in poclbm.
- Change email due to SPAM
- api.c miner.php add a '*' to the front of all notify counters - simplifies
future support of new counters
- miner.php add display 'notify' command
- Small change to help arch's without processor affinity
- Fix bitforce compile error
- api.c notify should report disabled devices also - of course
- API returns the simple device history with the 'notify' command
- code changes for supporting a simple device history
- api.c Report an OS string in config to help with device issues
- api.c fix Log Interval - integer in JSON
- api.c config 'Device Code' to show list of compiled devices + README
- api.c increase buffer size close to current code allowable limit
- removed 8-component vector support from kernel, as this is not supported in
CGMINER anyway
- forgot to update kernel modification date, fixed Wink
- reordered an addition in the kernel, which results in less instructions used
in the GPU ISA code for GCN
- miner.php: option for readonly or check privileged access
- Ignore reduntant-with-build options --disable-gpu, --no-adl, and --no-restart
- miner.php: ereg_replace is DEPRECATED so use preg_replace instead
- Make curses TUI support optional at compile-time.
- Bugfix: AC_ARG_WITH provides withval instead of enableval
- miner.php split devs output for different devices
- api.c: correct error messages
- icarus.c modify (regular) timeout warning to only be debug
- icarus.c set the windows TODO timeout
- Allow specifying a specific driver for --scan-serial
- optimized nonce-check and output code for -v 2 and -v 4
- Bugfix: Check for libudev header (not just library) in configure, and document
optional dependency
- Add API support for Icarus and Bitforce
- Next API version is 1.4 (1.3 is current)
- README/api.c add "When" the request was processed to STATUS
- Bugfix: ZLX to read BitFORCE temp, not ZKX -.-
- Use libudev to autodetect BitFORCE GPUs, if available
- Use the return value of fan_autotune to set fan_optimal instead of passing it
as a pointer.
- Pass the lasttemp from the device we're using to adjust fanspeed in twin
devices.
- fix the name to 3 chars, fix the multi-icarus support
- Bugfix: "-S auto" is the default if no -S is specified, and there is no such
delay in using it
- README add information missing from --scan-serial
- Update README RPC API Version comment
- Bugfix: Allow enabling CPU even without OpenCL support
- Change failed-to-mine number of requested shares messge to avoid segfault on
recursive calling of quit().
- Get rid of extra char which is just truncated in poclbm kernel.
- only small code formating changes
- removed vec_step() as this could lead to errors on older SDKs
- unified code for generating nonce in kernel and moved addition of base to the
end -> faster

Finally managed to get to my target hashrate for the 7970 with my latest kernel changes to poclbm (at 1200/1050+5%):
 GPU 0:  73.0C 3764RPM | 720.0/719.8Mh/s | A:186 R:0 HW:0 U:10.19/m I:11

12.2 was a bit of a mess and was unstable for me on linux+7970 too. 8.921 (which was the 7970 specific driver before 12.2) and 12.3 were better for me.
10105  Bitcoin / Mining software (miners) / Re: CGMINER GPU FPGA overclock monitor fanspeed GCN RPC linux/windows/osx 2.3.1 on: March 30, 2012, 09:28:37 PM
Wow thanks. If it does nothing at all positive then it's not worth it.

I've been using this for over a month now. Smiley

Code:
#elif defined VECTORS2
uint result = W[117].x ? 0u:W[3].x;
     result = W[117].y ? result:W[3].y;
if (result)
output[FOUND] = output[NFLAG & result] = result;
This fell into the category of changes known as: I tried it, it compiled differently to less ALUs, but I could not demonstrate any benefit.

I've made a couple of what I believe to be low-risk changes to the phatk kernel in the git tree. Given how precarious this kernel has shown to be in the past, I would like it if someone has an R5xxx card and runs from git could please git it a try and confirm no loss of hashrate. Thanks.
Good job, I'm glad to report zero performance loss on either VLIW-4 or VLIW-5 cards.

The bad news is, there's no noticeable gain either - I believe at this stage it would take no less than three 8-level wizards, an ancient grimoire, a bucket of cat blood and a slew of minor magical odds and ends to boost the hash rate.
At least git update 532179b24d made the code more elegant...
Thanks very much.

Thanks.

Finally upgraded to linux 12.3 driver. This one isn't as shit as 12.2 which was making my 7970 die. No difference to performance (as it is the identical 898.1 SDK) so a safe choice for GCN users.

GPU mining sure can be exciting...
Con, you might be interested in P4man's solution. Fastening the fan with duct tape won't void your warranty.

BTW, whatever did happen to that PSU of yours? Feel like sharing some data points? What make and model was it? What load did it typically pull?
Oftentimes, glitches at the production plant like solder points with inadequate amount of solder won't be severe enough to render the device completely inoperable but they will make themselves known (perhaps even with a bang and some fireworks) as the load increases.
Heh I don't have room to stuff a fan over that.

The PSU I actually am still happy with now even though it failed. It was an OCZ gold 1250W and it was pulling about 1300W for about 7 months. It went poof on fan spin-up as well.

GPU mining sure can be exciting. I had a reference fan on one of my sapphire 6970s fail in spectacular fashion last night. About 1/8th of the blades came flying off into the GPU and then it seized. The GPU still works but obviously won't cool so I can't mine with it. It happened on start up when the fans spin up abruptly to 85% so I've reluctantly relinquished that default speed now to a much gentler 50% on autofan startup and autofan management should be fast enough to raise it if necessary. It's still under warranty, and at least the rest of the machine is still running so nothing like the PSU drama I had and the mobo one before it. Sheesh...

Well, I tried installing 12.1/2.5, but now my computer won't boot past the Ubuntu loading screen. Kinda considering just going back to Windows now.

12.1 and sdk 2.5 is the least worst -recent- driver sdk combo. 11.6/2.5 is good but wont install on new linux versions.
Alright, I'll have to look into it. I dunno why it would start messing up after a random system update though. Seems weird to me.
That's because you're thinking "update" means better... I wish the world was like that. Likely xorg had some update which made the AMD driver weirdness become even weirder, or you got yourself a new AMD driver in the process.

AMD  fail. Dodgy driver/SDK combo for your hardware. Downgrade your driver to a less bad one.
I would, but I haven't found a decent guide anywhere to downgrade properly. What was the optimal driver/SDK combo for 6000 series cards again anyway?

Just started getting this today after an update told me to restart.

Try again please with the updated git now. (only diablo kernel has been changed this time).
no problem:
between 188 and 190 MH/s

Thanks! it works!

But in average it seems to be 2 MH/s lower...
It's the same kernel. Limitations of the goddamn annoying hashmeter over a small timeframe (hence why I introduced the benchmark parameter). Thanks for testing.

yes...  know, but I prefer the default kernel (is it diabolo?) since I tested all of them a while ago and diabolo was the fastest. Therefore I prefer to work with the older git version...   but why did the hashrate drop?
The kernels have radically changed and I need to choose the right ones. I'm asking you because I need your feedback, i'm not telling you a workaround. You are running very experimental code by trying the git tree.
Ok, of course, sorry:
Current Git:
diablo: 175  MH/s
poclbm: 157 MH/s
phatk: 168 MH/s
poclbm: 160 MH/s

Git from 3/3/2012:
default/diablo: 190 MH/s


Everything on Ubuntu 11.10 64bit, with HD5770 , Intensity 9, no overclocking/underclocking ,
ADL SDK 3.0
APP SDK 2.6  RC3
Cataclyst 12.2

Should I test all the kernels with the older git, too?

Con,

ckvolias:using latest cgminer 2.3.1-2 win7 64x
after awhile I loose temps and fan speed displays both on screen and from API - a cgminer reboot fixes the issue
Windows driver ATI Display Library fsckage. I can't do anything about it. Does restarting cgminer fix it or rebooting the machine fix it? I could probably try working around the former by detecting "losing adl support" and re-initialising it.
Restarting cgminer always fixes it, no need to restart the whole box.

Is this still something you consider adding to cgminer?
Yes.

No, that's cool thanks very much. What a pain. Fixing diablo on 7970 for the earlier 2.6 SDK seems to ruin vliw5. Oh well I guess I can just leave diablo kernel as is and just work with poclbm for 7970.
