parfquad

Numerical quadrature of polynomials using parallel constructs in Fortran

Features

• Equally-spaced trapezoid rule for quadrature of polynomials
• OpenMP parallelism for main part of quadrature loop
• Text (console) input of problem parameters, including:
  • Polynomial order
  • Polynomial coefficients (from 0th coefficient to nth)
  • Integration bounds (lower, upper)
  • Number of integration points (inclusive of bound points)
  • Number of OpenMP workers/threads

Compilation

This was built using Intel Fortran compiler and OpenMP via Intel OneAPI.

To build, please:

1. Navigate to the directory containing the parfquad.f90 file in an Intel OneAPI command prompt for 64-bit systems. This is necessary to have all of the proper environment variables.
2. Run the following command to build the source files to an .exe:

   ifx /Qopenmp /real-size:64 /integer-size:64 parfquad.f90
   

3. Run the exe in a similar OneAPI command prompt. This is the easiest way for the executable to see the OpenMP libraries.
