Raw UAV crashes computer

The attached code crashes my computer. Can anyone tell me what I am doing wrong?

Catalyst 10.8 drivers, and Windows 7 x64.

Raw UAV crashes computer

Any ideas? I'm stuck on this rather badly?

Can anyone (especially at AMD) reproduce this?

If this is not the correct method to use raw UAVs, then can someone at AMD provide a simple example of the correct method?

 

Thanks,

Malcolm

malcolm,
grid.gridSize.width = 4096;
grid.gridBlock.height = 1; <--- this should be gridSize not gridBlock.
grid.gridBlock.depth = 1;<--- this should be gridSize not gridBlock.

It looks like the gridsize might be uninitialized, causing an issue.

Awesome! Thanks Micah!

Chalk that one up to copy and paste... I feel kindof stupid for not spotting that one myself... Oh well.

 

Thanks,

Malcolm
