What is parallel computing?

Parallel computing refers to writing programs which are solved across multiple concurrent processes. This means that large problems (e.g. a fluid simulation) can be broken into smaller pieces (e.g. zones of the fluid domain) solved separately and more manageably.

Contents

• HW1: A simple parallel code where individual processes output their rank.
• HW2: A random matrix equation solver using the full Gauss-Jordan method.
• HW3: A program demonstrating MPI_Scan()- and MPI_Gather()-type routines.
• HW4: A program implementing a bubble sort using the non-blocking send routine MPI_sendrecv().
• HW5: A program conducting a stencil operation using the non-blocking send routines MPI_Isend() and MPI_Irecv().
• HW6: A program which distributes array elements amongst processors in an interleaved fashion.
• HW7: A program which solves a linear system of equations using the Jacobi method.
• HW8: A program which calculates the Fibonacci sequence recursively in parallel using OpenMP tasks.
