Until yesterday I didn't used it not at least fro running a simple cpp code.
After many hopeless tries for peoples help in implementing a simpe MPI Hello world code , I come o know that knowbody actually knows the robust way of using the hpc machine in my department.
Some outsider from Mech dept. suggested to check on search engines.
Hurray it is done absolutely simple in just 2 days with 1 hr per day .
First i did bash script job submission to run my Image processing code on HPC server without any mpi header file no mpi calls . On first trial itself i got my first queue Id from machine by using the simple command "qsub":D (try man(*nix))
Today I searched for mpi header file location and added it to PATH variable of env.
from there it took just 2 steps to feel the joy of triumph.
first compiled it with mpic++ -Wno-deprecated hello++.cc
added these lines to bash script , **above line**
mpirun -np 50 a.out
P.S: Some things are so simple to workout , but the cruel killer , the time plays an enigmatic role in making/doing it like a great deal of life making us some better sized jokers.
