clinfo

query OpenCL platform and device parameters

Build

clinfo is made from a single C source file. To build:

make

To install:

make install

To uninstall:

make uninstall

You can change the installation prefix by setting prefix and bindir. The default location is /usr/local/bin. If you would rather install in your home directory ($(HOME)/bin), you can do:

make install prefix=$(HOME)

Run

Just type: clinfo

clinfo displays the OpenCL platform and device parameters in a human readable form.

By default, clinfo only displays a few basic parameters. You can print them all with -a (or --all). You can also query specific parameters by listing them as arguments. For instance use clinfo CL_DEVICE_TYPE to query the device type of each device for each platform.

You can restrict the output to a single platform and even to a single device. For instance use clinfo 0:1 to restrict the output to device #1 of platform #0. To find out what is the number of a platform or a device, you can use -l (or --list).

The following options are available:

  • -a or --all : Display all parameters.
  • -h or --help: Display a short help notice.
  • -l or --list: List platforms and devices.
  • -r or --raw : Raw output (by default the values are pretty-printed).
