Slide 5 of 41
- Leadin: First, let us review some of the hardware features that influence the performance of single processor jobs.
- -The cpus are capable of producing 4 floating point operations per clock period, but this places a high demand for operands from memory
- -Part of the new memory hirearchy is that each processor has a 32 Kword cache for vector and scalar operations. (we will see more about this in a few slides)
- -To understand single process memory bandwidth a little better we need to take a closer look at the hardware layout
