Hi,
I am working on a particle simulation using C++ and MPI
I have a class particle as in the following,
class Particle{
float mass;
float charge;
float pos[3];
float vel[3];
int id;
//plus more data members
}
in the form of array say-: Particle simparticle[1000];
After each iteration, I want to broadcast the pos[3] and vel[3]
values but I dont want to BCast in bit and pieces, I wanted to
use a derived datatype that would automatically send the values
as once communication block.
Can it be done in MPI without serious overhead? If so any ideas
on how to construct the relevant data types? I constructed a
datatype using the full typemap but I am stuck on how to proceed
from there.
Thank In advance for you help
Leslie
