Hi I was wondering is there a limit on the number of work groups you can specify to the graphics card?. I have tried running on radeon 4870x2 for one core only the following:

# of Work Items = 2;

# of Work Groups = 1024x1024;

1 dimensional array to kernel  size = 2x1024x1024x4 bytes

1 dimensional array to kernel output = 2x1024x1024x4 bytes

It gives me an error message, saying it ran out of memory.
