did you look at readme.md on github?
first of all set -t parametr as 256 or 512
next set -b equil to SM count of your card
next set -p start from 128
then set -w as max as possible to your gpu memory, check -htsz params
-w 31 -htsz 29 need around 64GB of RAM to generate all arrays
-w 30 -htsz 28 need around 32GB of RAM to generate all arrays
-w 29 -htsz 28
-w 28 -htsz 27
-w 27 -htsz 25
if you will have free gpu memory you can increase -p or -b or -t  (all params multiple of 2)
