For you, guys. I have a screen of x17 sp mod.
Not bad but not one would expect for 0.8 btc ))))
All the trick is to mod mem allocation to support higher intensities ))
higher intensity means more rejected shares.
never trade 1% of hashrate for crazy high intensity.
alexis and tpruvot's miners (tpruvot uses one of sp_'s kernels for blake512_80) won't work with intensity higher than 21.3 on 10x0 series. Error in buffer allocation routine. So sp_ in his private mod changed something to avoid it. Maybe larger number for second param in launch config ... don't know ... int math and gpu-programming is difficult for me as I always worked with simulations with double type.
I see that alexis uses 128 registers (reg count) in default config but tpruvot uses less (80 as far as I remember) with some custom numbers for some algos. What is your recommendation for this setting? Does it really have affect on performance?
alexis can do >21 intensity.
it's tpruvot that can't, because of old simd code.
about regs, usually it's set by the launch config, not maxregs.
