Mapping Earth’s Seismic Waves, Supercomputer Style

Scientists have used a supercomputer to map 10 years of seismic waves on Earth in an effort to better understand the planet’s subsurface. Seismologists use devices called seismometers to measure motion on the ground, from earthquakes and volcanic eruptions to man-made explosions. The Earth also emits two types of weak, …

Which is Better: Parallelization or Vectorization?

Parallelization or Vectorization? It’s a slightly odd question, as ideally you would want both. But sometimes, you have to make a choice. Parallelization is where your application uses background threads to do the heavy lifting. Vectorization is where the special vector registers that are typically 128 or 256 bits long …
