Did you checked argon2i by using this script?

I modified argon2i to use ulong4 only when accessing to global memory
and is slightly faster for specific GWS and LWS. don't know if it's
faster overall but speed of argon 2i is better than previous record

previously - 6113
now - 6301

I have problems with this modification in argon2d so far

Did you checked TITAN using this script? If not I can check
