Hello,

I just released the gpu miners for yescrypt:

for nvidia cards (compute 35 and higher): github/djm34/ccminer-tpsp
for amd cards                                    : gihutb/djm34/sgminer

sgminer is still a work in progress, I am working on a new kernel
best setting so far for my 290x -w 32 --thread-concurrency 512 -I 9
It is difficult to go higher in intensity due to the high mem requirement. (also current speed is rather low... for the same reasons)
