Great work!

Did you have any luck in resolving the issue with using both bitblock & bitblockold kernels at the same time?

Thanks!

What's up dude, chiming in here since I'm usually over in the sgminer_5 multi-algo thread.

Your optimizations are pretty killer, pulling 3.6MH on a 290X.

It should be noted though I think that SPH_LUFFA_PARALLEL 1 is a killer for some cards that tend to go SICK, so people should maybe throttle back their overclocks.

I tried this version as is, with OC 1040/1300 and it threw a [questionable] card into SICK within 15 minutes, temps dropped on it to 40C and it basically just choked on a thread.  Scaled that card back to 1010/1250 [290X] and the uptime seems to be holding.

As you don't have any 290/X to test personally on, I'll definitely help wherever I can.  And I really like that you are releasing Windows binaries at the same time if not before the Linux compiles.  It was always a bitch and a half to wait for one of the few Windows compiling people to wake up and have the time to do that.

Very much fucking appreciated.  And I've backed you elsewhere in multiple threads already, as you may have seen dude.

Thanks sincerely for your contributions to the mining space so far.

Of course, if you have any more pull requests for sgminer v5_0 tree, please do not hesitate, ystarnaud has a shitload of commits going on over there as well; hopefully we can stay away from divergent forks, but whatever works right?

@divo2014, @havikk : i find out it's kidda hard to get multiple kernel into a pool configuration on this version, just threw away my 2 hours on that and still at nowhere
@platinum4 : SPH_LUFFA_PARALLEL 1 doesn't increase hash rate much so i guess just gonna remove it (copied from my x11 + x13 optimized )

We need to be able to use bitblockold and bitblock at the same time... many people have old + new cards in the same rig.

Trying to bypass it by ignoring the old card(s) always results in a freeze too, doh.

I have nvidia
and old amd R7 
X11
amd + ~ 15-18%

Thanks! 

Lol there was a mistake when i switch to the correct branch on github
re-downloadkernel/bitblock.cl or just add at line 81

What are the optimized starting parameters for 280x under linux ?

I'm getting around 1.000 MH/s and after 5 mins all cards are sick/dead with -I 18, -g 2 and worksize 256 (1100/1400)

They was running on default SHA256 algo i guess  
BTW here goes the config

Thanks for your help  

Running it stable for 14hours now, but using the 06252014 version..didn't test this version yet.
