BSGS Speed #252

Closed mr-fahrenheit-repo closed 1 year ago

mr-fahrenheit-repo commented 1 year ago

Is it possible to reach quetta keys/ second?

mirameshs commented 1 year ago

yes. Increase your ram to more than 4TB and use a xeon series CPU

mr-fahrenheit-repo commented 1 year ago

Is that really possible? So the speed doesn't depends on cpu cores? Can you show some math for that?

Sorry, i just really curious XD

mirameshs commented 1 year ago

in bsgs mode it depends on ram capacity. please check the end of keyhunt repo page. there is notes about k factor and n factor and also I have measurement based on experience.

Oh wow thanks for the info man. One more, is there any reason for using intel xeon cpu?

mirameshs commented 1 year ago

if you want to use a higher volume of ram, it is impossible to install them on PC. Almost the PC's RAM capacity is about 128 GB in maximum . so you should systems u can install more ram. it is often a server and servers use Xeon in most cases. there is another reason and it is related to Xeon architecture. server cpus have higher bandwidth to process data.

Sorry but is not possible to get that speed

It's about optimizing for Intel processors. I tried to run on amd 7763, and even xenon 8280 bypass it in speed. Although AMD is a generation higher.
