Hi,

I wrote a basic program that launch a specified number of similar tasks.
All the tasks run the same binary file. When the number of processes is
low (<25) all work fine: "pvm_spawn" returns 1 and a correct tid for
each process. If I try to launch more than 25 processes then pvm_spawn
returns the code 0 and a bas tids for the last processes (after the 27
first processes have been created). I there a limitation in the number
of processes Pvmd or Unix can handle?

Thanks,
