I have a dual AthlonMP 2200+
When I run seti with afinity set to use both processors, I can run the thread in REALTIME mode and keep OS responce and taskmanager shows processor usage @ 50percent or so.
If I run two copies of Seti and set the affinity to each one uses a different processor, I can only run the both @ below normal mode any higher and lose OS responsiveness but processor usage becomes 100%
does anyone know which is actually faster?
That sounds normal. Each instance of seti can only use one CPU. Windows processor usage is shown as the amount used out of all that is available. So 50% is one cpu in a dual setup. In realtime mode, one CPU is basically dedicated to seti exclusively, the other does everything else.
Two instances at below normal will leave both CPUs available for normal priority tasks, so response is not affected. You can probably set one seti instance to normal, and the other to below normal, and keep responsiveness.
To get minimum average times, running one instance at a high priority would do it. To get maximum output with probably somewhat longer average times, run two instances.
Personally I would run two instances for maximum output, both at low priority to keep system responsive.
Ty much for the input
