Just had 2.10.0 fail to failover on me. My configured pools are: stratum+tcp://us1.eclipsemc.com:3333 stratum+tcp://us2.eclipsemc.com:3333 stratum+tcp://eustratum.ozco.in:3333 http://api.mining.cz:8332api.mining.cz doesn't exist. use api.bitcoin.cz instead. Or, preferably, "stratum+tcp://stratum.bitcoin.cz:3333"

Sorry, I had a brain error when typing that, but I am indeed using http://api.bitcoin.cz:8332 (which auto-upgrades to Stratum anyway) I'll switch to the using the stratum+tcp URL if that's prefered. roy

I've just made cgminer 2.10.0 at Raspberry Pi to drive my Cairnsmore CM1. Looks like it performs a bit better than the same version on Win7 at i7-2600K.
normal, its linux ![Wink](https://bitcointalk.org/Smileys/default/wink.gif)

I guess this won't help you very much? I went back to Version 2.8.7 and it works like a charm on stratum... You only get a windows+stratum crash after 2.8.7?

Which is good because that's what it's supposed to be. Performance with current hardware (i.e. no asics) should have maximised with stratum support already. The changes in 2.10 are for the future.

It would appear that the latest version of cgminer still has no provision for mining different devices as different usernames and I need to run multiple copies of cgminer to accomplish this. Is this understanding accurate?
That's correct.

He stated earlier that he's using Gentoo (woohoo!).
AFAIK, there are no native cuda kernels for cgminer.
I thought there were *nix versions of those utilities. Didn't CGMiner used to have CUDA support?? Not that it matters this late in the game. The only openCL implementation for nvidia devices is through the cuda driver, meaning it goes cgminer->opencl->cuda->GPU. There is no way to do native cgminer->cuda->GPU. It's not at all worth it since the performance is identical, and they earn no money and GPU mining is on the way out. Throw me 1000 BTC and I'll make you a native cuda version, but it's not going to be of any advantage.

Bug report:
Not sure if there is a place I should report bugs or if this bug has been reported but I can't be bothered to find out so I figured reporting it here is better than nothing.
Bug: MH/s between GPU0 and GPU1 is flipped. Everything else is correctly matching the right GPU but apparently my 6950 is giving me 25MH/s and my 6450 is giving me 369MH/s. I upgraded from version 2.7.5 where this issue didn't exist. I have not tested just running one of my cards or with more than 2 cards. 6950 appears in the top line and 6450 appears in the bottom line. while the MH/s are reversed.
Setup: CGminer 2.9.7 Windows 8 GPU0 6950 unlocked xfx xxx GPU1 6450 gigabyte passive MSI motherboard with 2x pci-e 16x 8x 6950 in top slot
Coincidence related to something else maybe like a driver change. The GPU code hasn't been touched in any significant way in many months.

Despite the windows+stratum bugs that people are still encountering with 2.10.0, they are no worse than with 2.9.7, and no real showstopper bugs have shown up on 2.10.0 apart from lots of leaking shares when the primary pool is getwork without rolltime (which pools are still that bad!?). So despite the fact that windows+stratum disconnect is still problematic, I am going to raise the status of 2.10.0 to stable since it is no worse than the 2.9 branch. The substantial changes in 2.10 were all actually in the scheduling of work and there has not been a significant bug there as far as I can tell.
I will continue to pursue these windows bugs till no one is mining on windows any more... uh I mean till hopefully I can find wtf is uniquely wrong on windows. I'm so annoyed that 99% of my debugging effort is now directed to windows specific issues that I find myself wishing that I had made cgminer linux only. I could probably develop cgminer much faster if it was possible to drop windows support. Of course that's crazy talk...</rant>
EDIT: Note I will likely be releasing 2.10.1 shortly anyway.

I'm running cgminer 2.10.0 with us.eclipsemc.com:3333 instead of adding server numbers like us1.eclipsemc.com:3333 on Win7...I see less disconnects this way.

New version: 2.10.1, 14th December 2012
Mainly to try and fix the windows+stratum disconnect bug.
Human readable changelog:
Converted the curl code that was where all the crashing on windows was occurring into the raw code equivalents. Hopefully this quashes the crashes with stratum on various flavours of windows. Ztex and MMQ updates. Miner.php updates New API features and code improvements.
Full changelog:
- Check for EWOULDBLOCK when supported in send and recv as well. - Use the raw send() command instead of curl_easy_send since curl raw socket usage introduces random bugs on windows. - Use raw recv() command in place of curl_easy_recv since the curl implementation introduces random bugs on windows builds when the recv fails. - miner.php when displaying a single rig, add prev/next rig buttons if they exist, next to refresh - miner.php allow custom page joins for STATS - API show if pool has GBT (so people know not to use that pool) - miner.php - include windows easyphp link - driver-ztex: use the correct size for the swap array - API stats - display pool byte transfer stats - Pool store data transfer stats - README ModMiner dependency - Benchmark incorrect work size - ChangeLog refer to NEWS - MMQ handle over temp differently and hash longer - driver-ztex: search the complete noncerange based on the actual speed - README - update ModMiner details - API-README update - api use a dynamic io buffer, truncated before it reaches the current ~64k limit

I don't know if this is the right place to ask this, but has anyone tried to compile the stratum proxy for dd-wrt? Is it possible? How could I setup the compile environment?
Thank you all in advance.

This is not the right place. Check the stratum thread. And the proxy is in python so needs no compiling, just python.

As ckolivas said, there's no compilation involved. Please follow instructions from https://github.com/slush0/stratum-mining-proxy , it should work even on dd-wrt (it requires only python 2.6/2.7). Sorry for OT.

Just had 2.10.0 fail to failover on me.
Also it failed to failback. us1 came back last night, but as of this morning cgminer is still mining on us2 (even though the pool management screen shows all pools as alive). I thought that in the default failover policy it was supposed to failback to a pool higher up the list, once it's been stable for a little while? roy
