InvalidArgumentIndexComputeException()

[ozkan kayhan]

i changed my program to use doubles instead of floats to increase accuracy.
using double2 instead of float2 gives this exception.

I use…
    Kernel.SetValueArgument(3, new Vector2D(-1.5, -1.5));

and this line gives invalid argument index exception.

this worked fine with my float2 vector type Vector2F.

**// enables double types ?
#pragma OPENCL EXTENSION cl_khr_fp64 : enable

__kernel void GridUpdate
(
__global double2 * position,
__global int * particles,
double gridCellSize,
        double2 domainMin,
int gridCellCountx
)
{
size_t i = get_global_id(0);
int2 cell = (int2)((position_  - domainMin) / gridCellSize);
particles = cell.x + gridCellCountx * cell.y;
}_**

Darn, I must have missed your post. I'm sorry.

Does your GPU support doubles?

[ozkan kayhan]

I run this code on CPU instead of GPU during development. And my CPU supports doubles.

The error is only for "double2" typed arguments. "double" or "double2*" typed arguments works fine.

I can't compile your kernel at all. Problem is, I'm stuck with an old notebook for a couple of days.
What is your platform?

Sorry there is a typing error in that code.

__kernel void GridUpdate
(
      __global double2 * position,
      __global int * particles,
     double gridCellSize,
     double2 domainMin,
     int gridCellCountx
)
{
size_t i = get_global_id(0);
int2 cell = (int2)((position_ - domainMin) / gridCellSize);
particles = cell.x + gridCellCountx * cell.y;
}_

i cant seem to write "position_" to forums_

[ozkan kayhan]

there is an index in position and that doesnt  show on forums.

Yes, and I believe particles has one too. Anyway, I added the missing indices (which normally get converted to italic font tags) and enabled cl_amd_fp64 since I don't have support for the _khr_ one.  Other than that the code should be the same.
I compiled the program, created the kernel and tried setting the fourth argument with a two-double struct but couldn't reproduce the issue.
Any other info on this problem?
