OpenMP Warmup Exercise
11 September 2008

You were asked to write a code that computes the l1 norm of a vector of 1000 random entries, using OpenMP, and run it on the lab machines and the FSU HPC system. A worked out example is available:

• l1_norm, a program that takes the l1 norm of a vector.

OpenMP Exercises
15 September 2008

The exercises require access to source codes, which are available here:

1. hello, the OpenMP version of the "Hello, World!" program.
2. quad, a sketch of the program you will need to write.
3. fft, a Fast Fourier Transform program which computes time and MegaFLOPS.
4. md, a molecular dynamics program.
5. heated_plate, a program to solve the steady state heat equation in a rectangular region;
   grid_to_bmp, a C++ program which can display the solution produced by heated_plate.

OpenMP Assignment to be Turned In
by 19 September 2008

Insert OpenMP directives into a code for the Jacobi iteration. Run the resulting code on the HPC system, using 1 and 8 processors. Turn in the code, and the output of the two runs.

• jacobi, a program that applies the Jacobi iteration to a linear system.

You can go up one level to the Workshops page.
