我正在嘗試使用OpenCL(Java包裝,使用Eclipse)對一些數據執行一堆計算。內核本身不包含計算;相反,它需要其他功能來完成這項工作。OpenCL:可以乘以浮點數導致內部錯誤?
現在,有一個功能似乎是無效的或某事。這種精細運行:
int scaled(floatMemory fMem, int a, float b){
int result = indexAlloc(fMem);
float a0 = getf(fMem,a,0);
float a1 = getf(fMem,a,1);
float a2 = getf(fMem,a,2);
setf(fMem, result, a0, a1, a2);
return 0;
}
然而,這個代碼會導致內部錯誤(見倒數第二個發言):
int scaled(floatMemory fMem, int a, float b){
int result = indexAlloc(fMem);
float a0 = getf(fMem,a,0);
float a1 = getf(fMem,a,1);
float a2 = getf(fMem,a,2);
setf(fMem, result, a0*b, a1*b, a2*b);
return 0;
}
我嘗試了一些其他的邏輯測試,我想的東西是錯誤的浮點值'b'(即無限或空)。 任何人都可以驗證對我?
