OpenCL

The OpenCL support for the nu+ architecture is made through pocl.

How to install vanilla pocl

1. Download following the link.
2. In order to build pocl, you need the following support libraries and tools:
   • Latest released version of LLVM & Clang
   • GNU make
   • libtool dlopen wrapper files (e.g. libltdl3-dev in Debian)
   • pthread (should be installed by default)
   • hwloc v1.0 or newer (e.g. libhwloc-dev)
   • pkg-config
   • cmake
   • libclang-3.8-dev if you are using Ubuntu 16.04 LTS

   On Ubuntu 16.04 LTS you can run the following code on a terminal

   sudo apt-get install llvm & clang & libltdl3-dev & libhwloc-dev & libhwloc-dev & libclang-3.8-dev & make & cmake

3. Build and install

   cd <directory-with-pocl-sources>
   mkdir build
   cd build
   cmake [-D<option>=<value> ...] ..
   make && make install

Using pocl

To compile with pocl you have to execute:

gcc example1.c -o example `pkg-config --libs --cflags pocl`
