Now it is on bull(/home/myrice/GSoC/myrice-JtR). You can copy it from bull. In file xsha512_kernel.cl, line 217. There is a printf. When I run with ./john -te=1 -fo=xsha512-opencl -pla=1. There is segment fault. I suspect that the address store causes the wrong result on 7970. Since in my cuda code, I have experienced with memory align problem. That is, when I convert a struct* within a uint64_t varible to char*, the behavior is strange. So I will first eliminate all address store code. Thanks! Myrice .
