Multiple Core Processors-Multiple ASTK jobs was created by Kamil Gul

Hi All,

I want to know, on 2-core or 4-core processors, when you launch 4 analysis. Does 4 analysis is treated by 4 different cores, Each core selecting 1 analysis at the time?

Furthermore, i5 and i7 processors have 4 cores and each core divided into 2 threads. Is it possible to use 8 threads. ( I heard that threads cannot act independently within the core to which they belongs)

Any ideas?

Regards,

Kamil

Hi,

in all modern OS and more particularly on Linux, the processes are dynamically assigned to a core and can also migrate from one core to the other. That mechanism actually allows you to run many processes on few cores and the load is automatically balanced.

So the answer is Yes, you can use 4 cores by running 4 jobs in parallel and you don't need to do anything special for that kind of "parallel" simulation.

Hello Kamil Gul, Yes, it is possible to use the 4x2=8 cores of the i7 CPUs. Regards, JMB
