[理工] [計組] 95中山計組 weight 權重
2.2.(3%) The following table shows the number of floating-point operations
executed in two
different programs and the runtime for those programs on three different
machines:
Table 2:
─────────────────────────────────────┐
Program │ floating-point │
│ operation │ Execution time in seconds
────── ─────────┼───────┬──────┬─────┐
│ Machine A │ Machine B │ MachineC │
─────────────── ┼───────┼──────┼─────┼
Program1 │ 100000000 │ 1000 │ 100 │ 40 │
─────────────── ┼───────┼──────┼─────┤
Program2 │ 1000000 │ 1 │ 10 │ 40 │
─────────────────────────────────────
Assume that equal amounts of time will be spent running each program on some
machine. Which machine is fastest using the data of problem 2.2 table and
assuming a weighting that generates equal execution time for each benchmark
on machine A?
Which machine is fastest if we assume a weighting that generates equal
execution time
for each benchmark on machine B?
=======================================================================
這是95中山計組第2.3題
請問benchmark 還有weight是什麼意思呢?
weight要怎麼算???
這整題算出來的答案拿來比較 有什麼涵意嗎?
不然就算execution time就好了不是嗎
多利用weight有什麼用嗎?
