clinfo is a simple command-line application that enumerates all possible (known) properties of the OpenCL platform and devices available on the system.
Inspired by AMD's program of the same name, it is coded in pure C and it tries to output all possible information, including those provided by platform-specific extensions, trying not to crash on unsupported properties (e.g. 1.2 properties on 1.1 platforms).
clinfo [options...]
Common used options are -l to show a synthetic summary of the
available devices (without properties), and -a, to try and show
properties even if clinfo would otherwise think they aren't supported
by the platform or device.
Refer to the man page for further information.
- verify that your OpenCL environment is set up correctly;
if
clinfocannot find any platform or devices (or fails to load the OpenCL dispatcher library), chances are high no other OpenCL application will run; - verify that your OpenCL development environment is set up
correctly: if
clinfofails to build, chances are high no other OpenCL application will build; - explore/report the actual properties of the available device(s).
Building requires an OpenCL SDK (or at least OpenCL headers and
development files), and the standard build environment for the platform.
No special build system is used (autotools, CMake, meson, ninja, etc),
as I feel adding more dependencies for such a simple program would be
excessive. Simply running make at the project root should work.
The application can usually be built in Windows too (support for which
required way more time than I should have spent, really, but I digress),
by running make in a Developer Command Prompt for Visual Studio,
provided an OpenCL SDK (such as the Intel or AMD one) is installed.
Precompiled Windows executable are available as artefacts of the AppVeyor CI.
