Difference between processor CPU core in parallel launch
I don't understand very well the difference between "core" and "processor", so I am a bit confused in determining what is the maximum number of "processors" that I should consider for a parallel launch.
I was testing a machine with:
16 processors Intel(R) Xeon(R) CPU E5-2680 0 @ 2.70Ghz
therefore in my openFOAM test case I tried a simulation with 16 processors.
Then I realized that each CPU E5-2680 has apparently 8 cores:
does it mean that I can consider each core as a "processor" and run an analysis in parallel with 16 * 8 = 128 "processors" ?
Now I was testing
Can I conclude:
max "processor" number for parallel analysis = number of multicore processors * number of cores for each processor
is it right?
All modern cpu's today have more than one core. Each core can be considered a processor. If you have 16 cpu's and each cpu is built from 8 cores then you should be able to run 16x8=128 parallel processes.
