Find nvcc.profile (usually located in "C:is the scaling constant for vector y\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v5.0\bin") and replace everything inside it with this (if you have not changed it before):<pre>

The most important part to note is: "INCLUDES += ..." What you want to put is "-IC:/PATH/TO/THE/INCLUDE/FILES", which in my case was: "-IZ:/Program Files/Microsoft Visual Studio 11.0/VC/include". Hope this helps anyone, as it insanely irritated me as changing up the environment path on windows did nothing. ==Dynamically Allocated Shared Memory =Getting Started =Here is a roundabout way of working around the shared memory limitations of your graphics card.The idea is to send in chunks that your kernel can handle, then keep on Macsending chunks until there are none to be sent. The address being sent is also being shifted based on the chunk size.<div style='color:#000000;background:#ffffff;'> CHUNKSIZE <span style='color:#808030; '>=</span> <span style='color:#008c00; '>512</span><span style='color:#800080; '>;</span>http shared_ <span style='color:#808030; '>=</span> CHUNKSIZE <span style='color:#808030; '>*</developerspan> <span style='color:#800000; font-weight:bold; '>sizeof</span><span style='color:#808030; '>(</span>SimBody<span style='color:#808030; '>)</span><span style='color:#800080; '>;</span> <span style='color:#800000; font-weight:bold; '>while</span> <span style='color:#808030; '>(</span>chunks <span style='color:#808030; '>></span> <span style='color:#008c00; '>0</span><span style='color:#808030; '>)</span> <span style='color:#800080; '>{</span> BodyArray ba <span style='color:#808030; '>=</span> <span style='color:#800080; '>{</span> <span style='color:#808030; '>&</span>arr<span style='color:#808030; '>.download</span><span style='color:#603000; '>array</span><span style='color:#808030; '>[</span>index<span style='color:#808030; '>]</span><span style='color:#808030; '>,</span> CHUNKSIZE <span style='color:#800080; '>}</span><span style='color:#800080; '>;</span> SimCalc <span style='color:#808030; '><</span><span style='color:#808030; '><</span><span style='color:#808030; '><</span> numBlocks_<span style='color:#808030; '>,</span> numThreads_<span style='color:#808030; '>,</span> shared_ <span style='color:#808030; '>></span><span style='color:#808030; '>></span><span style='color:#808030; '>></span><span style='color:#808030; '>(</span>ba<span style='color:#808030; '>)</span><span style='color:#800080; '>;</span> cudaThreadSynchronize<span style='color:#808030; '>(</span><span style='color:#808030; '>)</span><span style='color:#800080; '>;</span> SimTick <span style='color:#808030; '><</span><span style='color:#808030; '><</span><span style='color:#808030; '><</span> numBlocks_<span style='color:#808030; '>,</span> numThreads_<span style='color:#808030; '>,</span> shared_ <span style='color:#808030; '>></span><span style='color:#808030; '>></span><span style='color:#808030; '>></span><span style='color:#808030; '>(</span>ba<span style='color:#808030; '>,</span> timeStep<span style='color:#808030; '>)</span><span style='color:#800080; '>;</span> cudaThreadSynchronize<span style='color:#808030; '>(</span><span style='color:#808030; '>)</span><span style='color:#800080; '>;</span> index <span style='color:#808030; '>+</span><span style='color:#808030; '>=</span> CHUNKSIZE<span style='color:#800080; '>;</span> <span style='color:#808030; '>-</span><span style='color:#808030; '>-</span>chunks<span style='color:#800080; '>;</span> <span style='color:#800080; '>}</span> chunks <span style='color:#808030; '>=</span> arr<span style='color:#808030; '>.</span>size <span style='color:#808030; '>/</span> CHUNKSIZE <span style='color:#808030; '>+</span> <span style='color:#008c00; '>1</span><span style='color:#800080; '>;</span> index <span style='color:#808030; '>=</span> <span style='color:#008c00; '>0</span><span style='color:#800080; '>;</span></div> = Converting Fortran Code to C Code =Sample code from the TOMO project - converted by James Boelen, Raymong Hung, and Stanley Tsang== Original Fortran Subroutine ==<pre>SUBROUTINE longtrack_self(direction,nrep,yp,xp,turnnow)!-------------------------------------------------------------------------! h: principal harmonic number! eta0: phase slip factor!

=Visual Studio 2017 and CUDA 9.1 Problem =I ran into this problem when trying to build '''thrust_sort.cu''' in the Thrust lecture. The only way I was able to build and run successfully was to create a '''CUDA 9.1 project'''. However, in the current version of Visual Studio 2017, unless you set the '''Platform Toolset''' to '''Visual Studio 2015 (v140)''', you will not be able to build and run CUDA 9.1 projects. This can be done by going to project properties, then to the General section, then changing the '''Platform Toolset'''. However, this is where I ran into a problem where Visual Studio would display an error and would not let me change the platform toolset. So I came up with the following workaround and it works:*If you haven't already done so, install the optional '''Visual Studio 2015 (v140)''' component which is available from the Visual Studio 2017 installer.*From Visual Studio, create a CUDA 9.1 project, then close the solution.*Using a text editor, open <project name>.vcxproj*Add the following as the first element in the XML under the '''Project''' tag: <nowiki><PropertyGroup> <CUDAPropsPath Condition==Troubleshooting=="'$(CUDAPropsPath)'==''">$(VCTargetsPath)\BuildCustomizations</CUDAPropsPath> </PropertyGroup></nowiki>*Replace all occurrences (there are 2 of them) of v141 with v140.Problem *Search for "CUDA 9.1" (you will find 2 occurrences). Then replace the first entire line with <code><nowiki><Import Project="$(CUDAPropsPath)\CUDA driver version 59.01.24 on MacBook Pro 2012 [http:props" /></nowiki></blogscode> and the second entire line with <code><nowiki><Import Project="$(CUDAPropsPath)\CUDA 9.adobe1.comtargets" /premiereprotraining></2012nowiki></08/known-issues-with-cuda-5-0-17-driver-including-crashescode>.*Close the file in the text editor then re-open the solution in Visual Studio. You should now be able to add your .cu files, build and-kernel-panicsrun.html Fix]
