However I cannot find any share, can be it because the work is discarded before Epiphany can find a valid share? I'm getting a lot of LONGPOLLs. In addition as you asked this is the work that I perform today: I implemented a couple salsa20_8 asm versions: The first one with bucles "Bor[i] = Bout[i] = (B[i] ^ Bx[i]);" and "Bout[i] += Bor[i];" rolled and using the instruction imadd, it save about 250B but the performance drops almost 0.5khash/s The second keep unrolled the bucles and uses the instruction imadd, it save only 50B but the performance also drops almost 0.5khash/s. At this point looks like imadd instrucction it so slow to be used but roll the bucle could be nice. Regards, Rafa. Content of type "text/html" skipped
