Can I use all Cores simulating with AVL?
I just wondered, if it is possible to use all the cores of my computer, so that the simulation would proceed faster. If it is possible, could somebody tell me, if I can adjust these new settings directly in AVL or do I have to do this with the Windows-Settings-window
How many cores do you have?
And you need to describe FIRE version and OS information.
Normally, MPI should speed up the calculation.
And HP-MPI library will be installed during FIRE installation.
When you click the "start calculation", "Job Setup" window will be popped up.
You can select "MPI" as simulation mode and define # of CPUs.
Very straightforward... Just try.
my sys is core i5...
How many CPUs can I use for fast running?
what host name is?
I don't know how many cores do you have in your system.
It depends on number of CPU cores.
my sys has 4 core...
what do you recommend for this CPUs?
In general, the use of detail chemistry results in long calculation time.
You can use all of cores for calculation.
And if you are using v2013, the option "clustering" or "multi-zone" for general gas phase reaction can be applied to reduce the calculation time.
when i use more than one CPUs in job setup I face this error:
mpirun: gethostbyname(amin) failed
mpirun: Line 1: Invalid hostname: amin
I don't know what I enter in the HOST name...
what should I do?
