Directions:

-- The environment variable OMPC_NUM_PROCS specifies the number of
threads to execute the program. For example, you want to use 4 threads,

        setenv OMPC_NUM_PROCS 4

 -- If the environment variable OMPC_NUM_PROCS is not set, check the
number of physical processors in your platform. The same number of
threads are created as the number of physical processor. 
In Linux and Solaris platforms, the runtime system checks the number
of processors. Otherwise, the current version uses a compile-time
constant N_PROC_DEFALUT (currently 4) in "ompclib.h" as the number of threads.
[[BR]]
 -- If the environment variable OMP_NUM_THREADS is set and its value
is greater than the number of threads described above, the value of 
OMP_NUM_THREADS is used as the max number of threads.
