Oclgrind 14.5 Pre-release
Pre-release

Initial release (beta).

Implements a SPIR 1.2 interpreter which can be targeted either via an
OpenCL 1.2 runtime API implementation or using a standalone kernel
interface.

Provides the following utilities:

  • Memory access error detection
  • Work-group divergence detection (barriers, async-copies)
  • Data-race detection (--data-races)
  • Simple interactive debugger (--interactive)
  • Instruction histograms (--inst-counts)
  • OpenCL runtime API error reporting (--check-api)
