Question at position $7$

Consider a computer with the following characteristics: the level$-2$ cache has an access latency of $8$ nanoseconds and a streaming transfer rate of $800$ MBper second, the main memory has an access latency of $60$ nanoseconds and a streaming transfer rate of $80$ MBper second, and a tape drive has an access latency of $60$ seconds and a streaming transfer rate of $2$ MBper second.

Compute the minimum transfer sizes that give acceptable utilization for cache, memory, and tape.

Compute the minimum transfer sizes that give acceptable utilization for cache, memory, and tape.

Cache $=2\mathrm{.}24$ bytes, memory $=1\mathrm{.}68$ bytes, tape $=40$MB

Cache $=2\mathrm{.}44$ bytes, memory $=1\mathrm{.}25$ bytes, tape $=4$MB

Cache $=1\mathrm{.}98$ bytes, memory $=2\mathrm{.}31$ bytes, tape $=15$MB

Cache $=2\mathrm{.}09$ bytes, memory $=1\mathrm{.}55$ bytes, tape $=42$MB
