Clojure wrapper & highlevel processing pipeline ops for JOCL/OpenCL
SimpleCL intends to enable a somewhat declarative interop approach between Clojure and OpenCL compute kernels. It provides thin wrappers for basic OpenCL data structures (contexts, devices, buffers, programs, kernels), as well as an highlevel API to define & configure multi-kernel & multi-program workflows and transforming data between Clojure’s data structures and their native OpenCL representation as byte buffers.
SimpleCL is still a young project (although it’s was originally created in 2012, it has been dormant for a while), yet has been sucessfully used in production in several projects and is fairly well documented.
Recent additions include adding support for image operations in OpenCL.
[simplecl "0.2.3"]Please see the extensive doc strings in the source and the examples below:
TODO: WARNING: Hello CL example is currently broken.
A trivial “Hello world” style example is located in this namespace. It defines a kernel to factor two float arrays and shows the required steps to run this on either CPU or GPU devices (by default the most performant is chosen automatically):
;; chooses max performance device lein trampoline run -m simplecl.test.hello ;; or force usage of given device type lein trampoline run -m simplecl.test.hello gpu lein trampoline run -m simplecl.test.hello cpu
A simple image processing example if located in this namespace. It defines a kernel that inverts an image.
