uncomplicate.clojurecl.legacy

Legacy alternatives for the functions from the core namespaces. If you need to use functions that were removed from the latest standard look for them here. Usually, they will be the same or similar to core functions, but will be suffixed by the largest version number that they support. Notable example is the command-queue-1 function that is required if your platform does not support at least OpenCL 2.0.

command-queue-1

(command-queue-1 ctx device x & properties)(command-queue-1 ctx device)(command-queue-1 device)

Creates a host or device command queue on a specific device.

** If you need to support legacy OpenCL 1.2 or earlier platforms, you MUST use this function instead of [command-queue], which is for OpenCL 2.0 and higher. What is important is the version of the platform, not the devices.**

Arguments are:

  • ctx - the cl_context for the queue;
  • device - the cl_device_id for the queue;
  • x - if integer, the size of the (on device) queue, otherwise treated as property;
  • properties - additional optional keyword properties: :profiling, :queue-on-device, :out-of-order-exec-mode, and queue-on-device-default;

Needs to be released after use.

See also command-queue-1*.

If called with invalid context or device, throws ExceptionInfo. If called with any invalid property, throws NullPointerexception.

command-queue-1*

(command-queue-1* ctx device properties)(command-queue-1* ctx device size properties)

Creates a host or device command queue on a specific device.

** If you need to support legacy OpenCL 1.2 or earlier platforms, you MUST use this function instead of [command-queue*], which is for OpenCL 2.0 and higher. What is important is the version of the platform, not the devices.**

Arguments are:

  • ctx - the cl_context for the queue;
  • device - the cl_device_id for the queue;
  • size - the size of the (on device) queue;
  • properties - long bitmask containing properties, defined by the OpenCL standard are available as constants in the org.jocl.CL class.

This is a low-level version of command-queue-1.

If called with invalid context or device, throws ExceptionInfo.

See https://www.khronos.org/registry/cl/sdk/1.2/docs/man/xhtml/clCreateCommandQueue.html, http://www.jocl.org/doc/org/jocl/CL.html#clCreateCommandQueue-org.jocl.cl_context-org.jocl.cl_device_id-long-int:A-

Examples: (command-queue-1* ctx dev 524288 (bit-or CL/CL_QUEUE_PROFILING_ENABLED CL/CL_QUEUE_ON_DEVICE)) (command-queue-1* ctx dev CL/CL_QUEUE_PROFILING_ENABLED)

with-default-1

macro

(with-default-1 & body)

Dynamically binds *platform*, *context* and *command-queue to the first of the available platforms, the context containing the first device of that platform, and the queue on the device in that context. Supports pre-2.0 platforms.
