5F→:感覺是存取違規才發生當中一個點中斷結束，你要不要檢查一下08/07 16:53
6F→:你的資料切割範圍08/07 16:54
5F推:你是用VC嗎??若是的話記得在專案內容中->C/C++-內將/openmp12/20 21:27
6F→:選項由no改為yes12/20 21:27
7F→:現在的情況是你程式只有用一個cpu但是執行續有兩個12/20 21:29
8F→:你的目標應該是兩個cpu分別各自使用程式的執行序吧12/20 21:30
11F→:我覺得你這樣子寫會有mutex還是rasing的問題, 把int test12/20 22:04
12F→:放到pragma程式區塊中應該會快起來12/20 22:05
13F→:確保變數為兩個副本12/20 22:05
7F→:可是對於32-bit的指令執行在32-bit的環境, 會用到16-bit11/17 21:29
8F→:的register嗎?11/17 21:29
9F→:我只是想問說他從memory到cache這塊的取法11/17 21:29
10F→:因為32-bit的處理器不可能傻傻的為了1-byte只取1-byte吧11/17 21:30
12F→:所以問題無解嗎@@" 我只是想知道一下大部份的做法11/17 23:21
17F→:了解, 那如果說是在第一次取資料的情況, 應該也會將unsigned11/18 07:08
18F→:short一併存進快取中提升其cache hit rate?11/18 07:10
3F→:這本有C語言版的.....10/20 16:47
14F→:你有把library裝起來嗎??10/19 23:50
17F→:= =沒有libary當然會有問題, 那個範例沒有問題, 而是你10/20 16:43
18F→:mpicc只是一個script當中用gcc編10/20 16:44
21F→:去找找mpich2....10/21 02:25
12F→:for(i=rank; i<max; i+=size), 你要的是這個東西嗎?10/14 15:35
13F→:另外除了mpi外, 你應該還要去研究什麼是平行處理10/14 15:44
9F→:因為對學生而言指標目前學到應該還沒有什麼花樣可以玩05/29 16:56
10F→:就想來點不同的試試XD05/29 16:56
13F→:那個想請問一下L大在高層陣列再加星的用意是...05/29 18:20
16F→:其實我是想問LPH66 orz05/29 19:20
20F→:了解, 感謝!05/29 19:59
22F→:也感謝樓上XD05/29 20:31
1F→:前面加fflush(stdin)?04/15 02:24
4F→:用release mode編?04/14 16:48
1F→:老問題, 你犯了第二戒, 第98行看一下, 另外請記得使用delete04/07 18:35
5F→:我的做法是一行一行找, 因為目前這類程式好像也沒有debugger04/07 19:30
