which is the command to tell the miner to use only a certian cpu core?
Thats a trick question, right? DiabloMiner uses 1% cpu or less typically.
not really, i have an java.exe usage of exactly 25% and 38 mb (i dont care about the memmory usage).
its not the 100% cpu bug, some light version of it xD
START "miner" /LOW /AFFINITY 1 diablominer.exe whatever
and yes, it is the same cpu bug. it's 100% on one core. if you got multiple miners, it's probably smart to dump all your miners into one core to reduce wasted processing power.
