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? 這是題目連結http://www.lib.nsysu.edu.tw/exam/master/eng/infoe/infoe_95.pdf -- ████ ████ ◢███ ◢███ ◢ ◢ ◣◢ █ █ █ █ ███◣ ◢◤◢ ◥◤ ███◣ ███◣ ███◣ ███◣ █ █ ◢█▆◤ █ █ █ █ █ █ █ █ ◥███◣ ◢◤◣ ███◤ ███◤ ◥██◤ ◥██◤ █ █ ◢█▆█◣ -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 122.123.81.185
