Re: [ANN] CREPCOIN: Start mining now with low H/S devices!

Can that miner use more than 1 thread/core?

Edit your config.txt:

2 cores

Code:

"cpu_threads_conf" :
[
{ "low_power_mode" : false, "no_prefetch" : false, "affine_to_cpu" : 0 },
{ "low_power_mode" : false, "no_prefetch" : false, "affine_to_cpu" : 2 },
],

4 cores

Code:

"cpu_threads_conf" :
[
{ "low_power_mode" : false, "no_prefetch" : false, "affine_to_cpu" : 0 },
{ "low_power_mode" : false, "no_prefetch" : false, "affine_to_cpu" : 2 },
{ "low_power_mode" : false, "no_prefetch" : false, "affine_to_cpu" : 4 },
{ "low_power_mode" : false, "no_prefetch" : false, "affine_to_cpu" : 6 },
],

etc...

Configured to my i7 as above I get 200 h/s at 50% CPU usage presumably because all 4 physical cores are active. When I enable all 8 cores from 0-7, my CPU is at 100% usage but my hash seems to be limited to around 170 h/s.

Is this an expected result seeing the virtual cores take processing time from the physical cores or is this an anomaly?

The same for me. I get about 130 h/s at 50% CPU for 4 cores. If set to all 8 - 90 h/s and 100% cpu usage.

Not the best miner...but similar wierd results as you.
Ryzen 1800X gets 95 h/s 16 threads, but 550h/s 8 threads.
go figure
About 3 hours got me 37 coins

Cryptonight algo needs 2Mb per thread. When hhread has less than 2Mb performance decreases.

Ryzen 1800X have 4Mb L2 cache and 16Mb L3. 10 threads should brings best results.

This makes sense. My i7 6700k has 8mb L3 + 1mb L2.

Thanks
