Invoke profile function in Nsight

When using Nsight to develop CUDA program, you can use profile function to profile the program:

1

You can also toggle the C/C++ and profile view in the right corner:

2

BTW, if you only want to profile a part of the program (not the whole), you can usecudaProfilerStart() and cudaProfilerStop to surround the code, then untick “Start execution with profiling enabled” in “Profile Configuration“:

Import existing CUDA project into Nsight

The steps to import an existing CUDA project (who uses CMake) into Nsight are as following:

(1) Select File -> New -> CUDA C/C++ Project:

1

Untick “Use default location“, and select the root directory of your project.

(2) Change Build location in Properties to points to the Makefile position.

2

(3) After building successfully, right click project: Run As -> Local C/C++ Application, then select which binary you want to execute.

Enable C++11 support for NVCC compiler in Nsight

When using Nsight as an IDE to develop CUDA programs, sometimes, the program may require C++11 support, otherwise errors like this will occur:

/usr/lib/gcc/x86_64-pc-linux-gnu/5.4.0/include/c++/bits/c++0x_warning.h:32:2: error: #error This file requires compiler and library support for the ISO C++ 2011 standard. This support must be enabled with the -std=c++11 or -std=gnu++11 compiler options.
 #error This file requires compiler and library support \
  ^
make: *** [src/subdir.mk:20: src/cuHE_opt.o] Error 1

To enable C++11 support, you need to do following configurations:
(1) Right-click the project, and select the last item: Properities.

1

(2) Check Settings->Tool Settings->Code Generation->Enable C++11 support (-std=c++11).
