cuda invalid配置參數

Question

我想用一些params來啓動一個內核，我相信這個參數是有效的，但我正在接收無效的配置參數錯誤。

我設置的大小是這樣的：

dim3 BlockDim = dim3(128, 1, 1); 
dim3 GridDim = dim3(321, 320, 1); 

，然後推出我的內核

kernel<<<BlockDim,GridDim>>>(); 

我的理解是，這應該是罰款。 從設備查詢我得到：

我在這裏錯過了什麼嗎？

多試驗幾次我已經運行：

作品

dim3 BlockDim = dim3(128, 1, 1); 
dim3 GridDim = dim3(200, 1, 1); 

不工作

dim3 BlockDim = dim3(128, 1, 1); 
dim3 GridDim = dim3(30001, 1, 1); 

Answer 1

想通了。

我有blockDim和gridDim在我的內核調用逆轉。

本來應該是：

kernel<<<GridDim,BlockDim>>>();
