Title: Mining with virtual cores? / Limiting them?
Post by: derrend on July 23, 2013, 07:21:17 PM
Hi everyone,

I'm cpu mining with an intel i5 dual core which is virtualised into 4 cores on ubuntu,
when i give the command 'setgenerate true 3' to the qt client, what does it mean?

system monitor shows that the unused core is kind of spread over over all 4 threads and the graph lines it generates become spaghetti.

Am i breaking my cpu??

Thanks in advance.

That sounds like the threads aren't properly bound to cores.

Try using cpuminer as that properly binds threads to cores.

I strongly doubt you are breaking your CPU, but as a general rule, try to mine with a power of two number of cores (1, 2 or 4 in your case) to avoid things like that.

While this may not break your CPU fast, It's not worth CPU mining as you will NEVER make a profit and will be making a LOSS doing it.
