• TypeNames and objects, e.g. const Event event;
• close namespaces with a comment: } // namespace itsName
• Makros with newlines: align \ symbol to column 80
• Describe how PreProcessor Macros are unrolled (excellent example)

/*      < typename T0, ... , typename TN    > */
template<BOOST_PP_ENUM_PARAMS(N, typename T)>
/*                      ( const T0, ... , const TN        ) */
HDINLINE void operator()( BOOST_PP_ENUM_PARAMS(N, const T)) const

In general, check the crt/host_config.h file to find out which versions are supported. Sometimes it is possible to hack the requirements there to get some newer versions working, too :)

Thrust version can be found in $CUDA_ROOT/include/thrust/version.h.

How to be a King of your own Python

Besides best intentions, pre-installed and not correctly (cross-)compiled modules are painful when living on the cutting-dev-edge. Let's start from scratch! :)

The following intro is necessary for a cluster environment where every binary needs to be cross-compiled and $HOME is not mounted on the compute nodes. Furthermore, cross-dependencies and ABI incompatibilities force you to build the full software stack with the same compiler.

Environment Vars
