Declare thread group size.

dcl_thread_group x, y, z
Item Description
x
 [in] An usigned 32-bit integer. 1 <= x <= 1024
y
 [in] An usigned 32-bit integer. 1 <= y <= 1024
z
 [in] An usigned 32-bit integer. 1 <= z <= 64

Remarks

x*y*z <= 1024

This thread group declaration must appear once in a compute shader.

This instruction applies to the following shader stages:
