Open vbadicut opened 1 year ago

vbadicut commented 1 year ago

ubuntu server, 64GB DDR5, i5-12400, 2TB 970 EVO (tmp drive), 3060Ti. First plot around 20min, second plot always very slow that I end up cancelling it. ./cuda_plot_k32 -n 2 -C 8 -M 60 -d /mnt/plot1_31/ -t /mnt/tmp/ -3 /mnt/tmp/ Tried various -M values, C 7 - still no avail Any advice is appreciated

Most likely not enough free RAM

Try -M 32, or without -M. Using -M causes more RAM to be used, due to copy buffer overhead.

./cuda_plot_k32 -n 2 -S 2 -C 8 -M 20 -d /mnt/plot1_31/ -t /mnt/tmp/ -3 /mnt/tmp/

thanks for the advice....formatted the tmp drive and seems better now, around 10m per plot...is there a recommended file system, eg ext4, btrfs ?

madMAx43v3r commented 1 year ago

ext4 is fine
