Intel ha rilasciato il SDK 1.5 di OpenCL. Download del SDK per sistemi Windows e Linux a partire da questa pagina.

Performance Enhancements

• Intel® Advanced Vector Extensions (AVX) code generation – full utilization of the Intel® 2nd generation Core™ Processors SIMD vector width.
• Improved barriers – performance improvement when using the built-in work-group barrier function.

OpenCL Runtime Features

• New Intel extension: cl_intel_immediate_execution – Immediate Command Execution is an extension which enables you to execute OpenCL commands in a single-threaded manner, using the calling thread to perform the actual execution.

OpenCL Development Tools

• Intel® OpenCL SDK Debugger (beta version) – The Intel® OpenCL SDK Debugger is a Microsoft* Visual Studio* 2008 plug-in, which enables you to set breakpoints inside OpenCL kernels, examine values of variables, memory and stack trace.
• Intel® Graphics Performance Analyzers 4.2 (Intel® GPA) support of Intel® OpenCL SDK 1.5 provides full coverage of OpenCL on CPU profiling, including:
  distribution of the OpenCL commands and kernels, flow and dependencies between commands, duration of commands and kernels execution.
• New features in the Intel® OpenCL SDK Offline Compiler: Linux* OS support

Intel ha rilasciato la versione 1.1 di OpenCL SDK.
