Overview

This article describes a utility to help diagnose system and installation issues for Intel® Computer Vision SDK (Intel® CV SDK) for OpenCL™ Applications and Intel® Media Server Studio.  It is a simple Python* script with full source code available.

It is intended as a reference for the kinds of checks to consider from the command line and possibly from within applications.  However, this implementation should be considered a prototype/proof of concept -- not a productized tool.

Features

When executed, the tool reports back 

  • Platform readiness: check if processor has necessary GPU components
  • OS readiness: check if OS can see GPU, and if it has required glibc/gcc level
  • Install checks for Intel Media Server Studio / Intel® SDK for OpenCL™ applications components
  • Results from runs of small smoke test programs for Media SDK and OpenCL

System Requirements

The tool is based on Python 2.7.  It should run on a variety of systems with or without necessary components to run GPU applications.  However, it is still a work in progress so it may not always exit cleanly when software components are missing.

Using the Software

The display should look like the output below for a successful installation
