Type wrapper for openCL command queue objects
| Type | Visibility | Attributes | Name | Initial | |||
|---|---|---|---|---|---|---|---|
| logical, | public | :: | blockingWrite | = | .true. |
Enable/disable blocking writes when copying from host to device |
|
| logical, | public | :: | blockingRead | = | .true. |
Enable/disable block reads when copying from device to host |
|
| type(fclEvent), | public | :: | lastWriteEvent |
Focal event object for the most recent write event (host-to-device) to be enqueued |
|||
| type(fclEvent), | public | :: | lastReadEvent |
Focal event object for the most recent read event (device-to-host) to be enqueued |
|||
| type(fclEvent), | public | :: | lastCopyEvent |
Focal event object for the most recent copy event (device-to-device) to be enqueued |
|||
| type(fclEvent), | public | :: | lastKernelEvent |
Focal event object for the most recent kernel event to be enqueued |
|||
| type(fclEvent), | public | :: | lastBarrierEvent |
Focal event object for the most recent barrier event to be enqueued |
|||
| integer(kind=c_intptr_t), | public, | allocatable | :: | dependencyList(:) |
List of pre-requisite events for next enqueued action. All events in this list are used as dependencies for the next enqueued operation. At enqueueing, the list is cleared unless holdDependencies is .true. |
||
| type(c_ptr), | public | :: | dependencyListPtr | = | C_NULL_PTR |
C pointer to dependency list. C_NULL_PTR when nDependency is zero. |
|
| integer, | public | :: | nDependency | = | 0 |
Number of items in dependency list |
|
| logical, | public | :: | holdDependencies | = | .false. |
Set to true to not automatically clear dependencies after enqueueing. Use for applying the same dependencies to multiple commands. Use fclClearDependencies to clear and reset. |
