  2. arm7 and arm8 working fine! There is a small delay before the engine starts to work, I think it will not affect its returns. Thank you Aprijal! Your work is appreciated!

  3. Any good news about multi threads?

    1. Multi threads work fine on my device.

    2. Mmm. Very exciting! Because we had first a build running multicore but with only 1 MB hash and a second build full hash but single core. If we have multicore and hash together now, I guess this time Ivan can reach 3050+ ELO in Rapidroid. You deserve congrats.

  4. On MTK6752: arm7 981 knps, arm8 1257 knps. CfA 5.2.5 / 8 cores / 256 hash / 1 minute. I'm happy with SMP functionality.

  5. Doesn't work with CfA on my device. It plays all games in 1 second and shows the result of tournament. Weird

  6. Sorry Aprijal, the engine is working fine. My stupidity I chose random play in CfA by mistake ;) Keep up the good work

  7. Very strong!Thanks for sharing Aprijal
