  • program compilation and execution (with multiple data sets)
  • crowd-benchmarking
  • statistical analysis of empirical results
  • plugin-based autotuning
  • automatic performance modeling
  • static and dynamic features extraction
  • learning to predict optimizations and run-time adaptation
  • reproducibility of experimental results

Installation

First install the CK framework as described here.

Then install this CK repository as follows:

 $ ck pull repo:ck-autotuning

You can now browse and reuse program workflows shared at the CK portal.

Please refer to the CK online guides including CK portable workflows and the autotuning example.

Troubleshooting

  • Issues with GLIBCXX_3.4.20/3.4.21 when using LLVM installed via CK: These sometimes occur on earlier Ubuntu versions (14.04) on ARM/x86. This can be fixed by upgrading to later versions of Ubuntu, or can sometimes be fixed by:
 $ sudo add-apt-repository ppa:ubuntu-toolchain-r/test
 $ sudo apt-get update
 $ sudo apt-get upgrade
 $ sudo apt-get dist-upgrade
  • Issues with libncursesw.so.6 (not found) on some older machines: It can be fixed by compiling and installing lib-ncurses with the support for wide characters. This can be done automatically via CK:
 $ ck install package:lib-ncurses-6.0-root
