Compute Elapsed Time

WTIME is a PYTHON library which examines methods for computing the elapsed CPU time of a part of a calculation.

In PYTHON, CPU time can be read using the clock() function from the time module:

        from time import clock

        t1 = clock ( )
        carry out operations to be timed
        t2 = clock ( ) - t1
        print 'Operations completed after %g seconds' % ( t2 )

TIMER is available in a C version and a C++ version and a FORTRAN90 version and a MATLAB version and a Python version.
