does memory allocation in gpu maks difference in speed?
how to know T, P and b optimal value for my card (3080)?
what is W and -htsz role?
and what is item size ?
can i occupy more ram in computer to give some speed boost as i have 128GB memory ? if yes how can ?
-t use 512 for your 3080
-b use 68, shoud be multiples of SM count your cars(3080 have 68 SM)
-p use 256, this value mean how many xpoints will compute each thread in kernel.
-w it is number of baby step, -w 26 mean create array with size 2^26 as large this array then more big giant step. But you should check you hashrate when increase -w it shodn`t drop more then 1.5 times. For ex, your hashrate with -w 26 is 1500 Mkeys and if with -w 27 your hashrate is more then 1000 mkeys then there will be sense to increase -w
-htsz use default 25, it is size of Hash Table. you can change -htsz only if you have small baby aray(-w) less then Hash Table size
