hey , I just figured out the problem. the -fopenmp was to be included in a
couple of places in my makefile due to which the openmp library was not
getting recognised though code was compiling.
Anyways if it is just one line of code and u dont need the braces after
omp parallel( it is just like a one line statement after 'if')
i have dual core.
thanks for yr help!
