argv

this is how we use MPI_Init function

int main(int argc, char **argv)
{
    MPI_Init(&argc, &argv);
…
}

why does MPI_Init use pointers to argc and argv instead of values of argv?

Sometimes MPI is used to send low-entropy data in messages. So it can be useful to try to compress messages before sending it. I know that MPI can work on very fast networks (10 Gbit/s and more), but many MPI programs are used with cheap network like 0,1G or 1Gbit/s Ethernet and with cheap (slow,… >>> More
