Package: libthrust-dev Version: 1.5.1-1 The description of the current libthrust-dev package in Debian is: "Thrust - C++ template library for CUDA".
It's quite misleading - as of now the Thrust library is fully usable without CUDA, e.g. as a template library for implementing parallel algorithms using OpenMP. On the Thrust website (http://code.google.com/p/thrust/) the package is described as: > Thrust is a parallel algorithms library which resembles the C++ Standard > Template Library (STL). Thrust's high-level interface greatly enhances > developer productivity while enabling performance portability between GPUs > and multicore CPUs. Interoperability with established technologies (such as > CUDA, TBB and OpenMP) facilitates integration with existing software. Develop > high-performance applications rapidly with Thrust! The Thrust documentation (http://code.google.com/p/thrust/wiki/DeviceBackends#Additional_Details), mentions also that: > When using either the OpenMP or TBB systems, nvcc isn't required. In general, > nvcc is only required when targeting Thrust at CUDA. For example, we could > compile the previous code directly with g++ with this command line... I'm using the current sid package on a machine without GPU, with gcc's OpenMP, and it works well. To conclude, here're three suggestions: - to rephrase the current package description to reflect that Thrust is no-longer a CUDA-specific tool - to change the type of dependency on nvidia-cuda-toolkit from recommends to suggests - to move libthrust-dev from contrib to main (suggested in an e-mail by Andreas Beckmann) HTH, best regards, Sylwester -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
