sudo ./evsets -b 15360 -c 30 -s 12 -a g -e 2 -n 20 -o 4096 -r 10 -t 95 -C 0 --verify --retry --backtracking --nohugepages

[-] No support for more than 8 slices ......

I get error "No support for more than 8 slices" when i try to find evict sets in Xeon-E5 2650l v3. The program is still running but there is no results. Can you give me some advice? Thank you~

I think that should only affect the verification, as it relies on the reverse engineered hash functions (see https://github.com/cgvwzq/evsets/blob/master/micro.c#L56), the problem might be that I overwrite the value (https://github.com/cgvwzq/evsets/blob/master/main.c#L135).

Try commenting out that if block and running it w/o --verify.

Also, for debugging purposes use hugepages, as it will be much faster (drop --nohugepages and use a larger offset -o N. If that doesn't work we'll see what else is broken...
