how to define number of cpus in simulation

hello, for CPU based simulations:

1) How do we define number of cores for the same servers? For example, I ran a simulation and it (automatically?) used all 28 cpus in that server. How do I restrict it to any number of cores I want to use?

2) How do we enable the simulation to run across multiple servers (with mpi)?


  • Reading the documentation (wiki and DualSPHysics_v5.0\doc\help) you can find that


      -ompthreads:<int> Only for CPU execution, indicates the number of threads by host for parallel execution, this takes the number of cores of the device by default (or using zero value)

    The mpi version is not released
