Hi everyone:

I have a question about the kernel max inputs and outputs. The user-guide denotes that the max inputs 128, max outputs 8. But now I have a problem. My program needs 9 outputs. The kernel is defined like this:

kernel void
gpu(
float t,
float nx, float ny, float nz4,
float dx, float dy, float dz,
float K_Gx_a[],  float K_Gx_b[],  float K_Ex_a[],  float K_Ex_b[],  float  K_Ex_c[],  float K_Ex_d[],
float K_Gy_a[],  float K_Gy_b[],  float K_Ey_a[],  float K_Ey_b[],  float K_Ey_c[],  float K_Ey_d[],
float K_Gz_a[],  float K_Gz_b[],  float K_Ez_a[],  float K_Ez_b[],  float K_Ez_c[],  float K_Ez_d[],
float4 HX[][], float4 HY[][], float4 HZ[][],
float4 FX0<>, float4 FY0<>, float4 FZ0<>,
float4 GX0<>, float4 GY0<>, float4 GZ0<>,
float4 EX0<>, float4 EY0<>, float4 EZ0<>,
float4 IND[][], float K_A[], float K_B[],
int PT_SOURCE_EX, int PT_SOURCE_EY, int PT_SOURCE_EZ, int N_COORD_PTSOURCE,
out float4 EX<>, out float4 EY<>, out float4 EZ<>,
out float4 FX, out float4 FY<>, out float4 FZ<>, out float4 GX<>, out float4 GY<>, out float4 GZ<>;

Is there any way to sovle the problem? And is there any global memory to be uesd so as that we do not need to put the FX....GX...(those 6 outputs) as outputs but just as global variables? Or any other tips?

My card is AMD HD4850 635/1986MHZ

THX for your help!
