whether to use exact or fast versions of some math library functions and operands), and register usage limits. About the only real compilation options that can effect performance are floating point compliance settings (ie.
#Cuda c makefile example driver#
nvcc uses very aggressive optimization settings during C compilation, and the PTX assembler and driver have a lot of internal architecture specific optimisations over which there is basically no programmer control. If you try and use those features without the correct flags, the compiler will generate warnings or errors.
#Cuda c makefile example code#
If you don’t use those features, the PTX code produced will be almost identical. This tutorial does not even scratch the surface of what is possible using make, but is intended as a starters guide so that you can quickly and easily create your own makefiles for small to medium-sized projects. Almost without exception, nvcc compilation flags only turn on specific architectural features at the PTX generation stage (things like double precision, atomic memory operations, C++ runtime support, in kernel printf support, etc). Makefiles are a simple way to organize code compilation. I guess there is a minimum set of flags that I need in order to ensure adaption to the local architecture. I doubt that has anything to do with compilation.
I guess there must be some kind of problem with this way, as my programs do work, but seem to be rather underperforming…
Will build an executable that will run on any CUDA compatible card, as long as source.cu doesn’t have any external dependencies outside of CUDA or the standard C/C++ library. it can be simpler than that: nvcc -o executable source.cu Nvcc -o EXECUTABLE_NAME “…/SOURCE_NAME.cu”-I/usr/local/cuda/include -lcudart -L/usr/local/cuda/lib cu code, what is wrong about compiling it with a simple call to It isn’t - you don’t need a makefile for trivial compilation. In this C++ Makefile tutorial, we will discuss the major aspects of Make tool and makefile including its advantages and applications in C++: In any C++ project, one of the important goals is to simplify the building of the project so that we get all dependencies and project files in one place and execute them in one go so that we get the desired output with a single command. I’m not certain about whay building a makefile in necessary.
