How can I get CMake to automatically detect the value for CUDA ...
2021年7月2日 · Newer versions of CMake (3.18 and later), are "aware" of the choice of CUDA architectures which compilation of CUDA code targets. Targets have a CUDA_ARCHITECTURES property, which, when s...

2013年4月25日 · sm_XY corresponds to "physical" or "real" architecture. compute_ZW corresponds to "virtual" architecture. not all sm_XY have a corresponding compute_XY. for example, there is no compute_21 (virtual) architecture
c++ - How do I set CUDA architecture to compute_50 and sm_50 …
2018年1月16日 · With CMake 3.18 there is the new target property CUDA_ARCHITECTURES. From the documentation here : set_property(TARGET myTarget PROPERTY CUDA_ARCHITECTURES 35 50 72)
differences between virtual and real architecture of cuda
2013年2月9日 · Trying to understand the differences between virtual and real architecture of cuda, and how the different configurations will affect the performance of the program, e.g.-gencode arch=compute_20,code=sm_20 -gencode arch=compute_20,code=sm_21 -gencode arch=compute_21,code=sm_21 ... The following explanation was given in NVCC manual,
CUDA: How to check for the right compute capability?
2013年10月8日 · CUDA code compiled with a higher compute capability will execute perfectly for a long time on a device with lower compute capability, before silently failing one day in some kernel. I spent half a day chasing an elusive bug only to realize that the Build Rule had sm_21 while the device (Tesla C2050) was a 2.0.
Understanding CUDA architecture when using WSL
2021年6月9日 · I am relatively new to using CUDA so I have a hard time understanding its architecture. So I have few questions. Is there a better documentation than CUDA on WSL User Guide? In the above picture, which step of CUDA on WSL User Guide installs what on which layer? a) Is (A) in above picture, installed by following Installing NVIDIA Drivers → CUDA on …
CUDA: How to use -arch and -code and SM vs COMPUTE
2016年2月26日 · (1) When no -gencode switch is used, and no -arch switch is used, nvcc assumes a default -arch=sm_20 is appended to your compile command (this is for CUDA 7.5, the default -arch setting may vary by CUDA version). sm_20 is a real architecture, and it is not legal to specify a real architecture on the -arch option when a -code option is also ...
How to check the Version of GPU to dynamically set ' …
2023年7月27日 · This was introduced with CUDA 11.5 update 1, per official documentation: 1.1.4. New -arch=native option In addition to the -arch=all and -arch=all-major options added in CUDA 11.5, NVCC introduced -arch= native in CUDA 11.5 update 1. This -arch=native option is a convenient way for users to let NVCC determine the right target architecture to ...
CUDA_ARCHITECTURES is empty for target "cmTC_28d80"
2021年6月14日 · It seems that it stands for particular architecture of NVidia cards for which the program shall be optimized or minimum architecture on which it shall run at all. I have found this link how these architecture numbers relate to the GPU used. To cite most important codes: Turing - CUDA 10+ - 75 CMAKE default. Ampere - CUDA 11.1+ - 80,86,87
cuda - What is the purpose of using multiple "arch" flags in …
2013年7月11日 · I've recently gotten my head around how NVCC compiles CUDA device code for different compute architectures. From my understanding, when using NVCC's -gencode option, "arch" is the minimum compute architecture required by the programmer's application, and also the minimum device compute architecture that NVCC's JIT compiler will compile PTX code ...
