  7. Scientific Computation

  8. Parallel computing - simultaneous use of multiple compute resources to solve a computational problem Why Parallel Computing? - to save time (wall clock time) - to solve larger problems - to alleviate memory constraints - larger databases Parallel Computing

  9. Grand Challenge Problems” - weather and climate - mechanical devices - from prosthetics to spacecraft - electronic circuits - manufacturing processes - geological, seismic activity - biological, human genome - chemical and nuclear reactions Parallel Computing

  10. Commercial applications - parallel databases, data mining - oil exploration - computer-aided diagnosis in medicine - management of national and multi-national corporations - advanced graphics and virtual reality, particularly in the entertainment industry - networked video and multi-media technologies - collaborative work environments Parallel Computing

  11. Ultimately, parallel computing is an attempt to maximize the infinite but seemingly scarce commodity called time Parallel Computing
