Introduction to High Performance Computing for Life Scientists

As the number of cores are increased, performance rarely scales linearly.

Scalibility changes as the size and complexity of the system is changed.

Scalibility can be meaningless if the work load is not distributed evenly among processors.

Larger systems scale better to large core-/node-counts than smaller systems.

Most HPC systems run UNIX or Linux as an OS.

Each application is a seperate process; the OS will schedule any process.

Threads are sub-processes that compose a process.

Hybrid MPI with OpenMP does affect performance.

When running hybrid jobs, placement across NUMA regions is important.
