Vulkan® 1.3.264 - A Specification (with all registered extensions)

31. Dispatching Commands

Dispatching commands (commands with Dispatch in the name) provoke work in a compute pipeline. Dispatching commands are recorded into a command buffer and when executed by a queue, will produce work which executes according to the bound compute pipeline. A compute pipeline must be bound to a command buffer before any dispatching commands are recorded in that command buffer.

To record a dispatch, call:

// Provided by VK_VERSION_1_0
void vkCmdDispatch(
    VkCommandBuffer                             commandBuffer,
    uint32_t                                    groupCountX,
    uint32_t                                    groupCountY,
    uint32_t                                    groupCountZ);

commandBuffer is the command buffer into which the command will be recorded.
groupCountX is the number of local workgroups to dispatch in the X dimension.
groupCountY is the number of local workgroups to dispatch in the Y dimension.
groupCountZ is the number of local workgroups to dispatch in the Z dimension.

When the command is executed, a global workgroup consisting of groupCountX × groupCountY × groupCountZ local workgroups is assembled.

To record an indirect dispatching command, call:

// Provided by VK_VERSION_1_0
void vkCmdDispatchIndirect(
    VkCommandBuffer                             commandBuffer,

    VkDeviceSize                                offset);

commandBuffer is the command buffer into which the command will be recorded.
buffer is the buffer containing dispatch parameters.
offset is the byte offset into buffer where parameters begin.

vkCmdDispatchIndirect behaves similarly to vkCmdDispatch except that the parameters are read by the device from a buffer during execution. The parameters of the dispatch are encoded in a VkDispatchIndirectCommand structure taken from buffer starting at offset.

// Provided by VK_VERSION_1_0
typedef struct VkDispatchIndirectCommand {
    uint32_t    x;
    uint32_t    y;
    uint32_t    z;
} VkDispatchIndirectCommand;

x is the number of local workgroups to dispatch in the X dimension.
y is the number of local workgroups to dispatch in the Y dimension.

    uint32_t                                    groupCountZ);

commandBuffer is the command buffer into which the command will be recorded.
baseGroupX is the start value for the X component of WorkgroupId.
baseGroupY is the start value for the Y component of WorkgroupId.
