<h3>Java OpenCL</h3>
Project JOCL provides an easy to use Java binding for the OpenCL API.
JOCL exposes the OpenCL API in two levels: A automatically generated low level JNI based binding
and a hand written high level binding on top of the generated interfaces.
The high level bindings provide a convenient interface and reduce verbosity to a minimum.
<h3>Features / Project Goals</h3>
<ul>
<li>high performance, cross platform, high and low level OpenCL 1.1 bindings</li>
<li>intuitive API</li>
<li>seamless interoperability with JOGL</li>
<li>secure - automatic Exception handling, no resource management in native code etc</li>
<li>GC friendly - no weak references, finalizers or other cheats</li>
<li>utility API for Program management, CommandQueue synchronization and more</li>
</ul>
