I finished all parts of this assignment, without needing to know much about CUDA. I was able to install VS 2015, Cuda 8, Cmake and Git Hub and I figured out how to fork.
I had a real problem with Cmake. The difficulty was that I had a previous installation of Visual Studio, 2017 that was enterprise. I didn't try to install cuda 8 on that because I believe cuda 8 does not support VS 2017 yet. Anyway, I then had two versions 2015 and 2017. When I ran Cmake, it would find the VS 2017 compiler and right away. THe message was that the compiler worked on a simple program. Later that build gave me issues and I thought that was unsolveable since cuda 8 does not support VS 2017 yet. I didn't try to get that to work too hard.
With VS 2015 it never found the compiler. I told it where the compiler was I got a large kryptic message that I posted on the google group. The suggestion offered by a TA didn't help either- I ran cmake from the command line and that didn't change the outcome. I came to the sig lab and with Josh and another student, they also couldn't sort it out either. I then uninstalled VS2017 and then it all went ahead as in the instructions. I shouldn't have needed to uninstall a working VS installation, but I saw no other choice. I think that when a later version of VS is installed, Cmake does not easily accept using the earlier version even though it claims otherwise.
I have a good command of Visual Studio so I figured out how to build the project easily.
I took a screen shot of the colored images. The build and run were straighforward.
.
Nsight was installed on my computer and I was also able to run the samples of Cuda 8. That told me that VS 2015 and Cuda 8 are installed and linked correctly.
I got the debugger to break during cuda compiling. I set the break point at line 30 and it stopped. I added a conditional break at index = 1200 and it stopped at 1200 as expected. Here is an image of that timeline.
I then looked at the autos and that confirmed that the index stopped at 1200.
I also got a screenshot of the block and thread that index= 1200 stopped at:
It all worked well on windows..Too bad I needed to uninstall VS 2017. didn't need to modify the CMakeLists.txt at all. There were variables in the cmake gui that I thought I may need to define but that was not necessary.
