Using GHC with NVCC

As an alternative to accelerate, I'm trying to call CUDA code over Haskell's FFI. Here's a simple program that fails to compile: cuda_code.cu: void cuda_init() { cudaFree (0); cudaThreadSynchronize (); } Test.hs: foreign import ccall…

CUDA C v. Thrust, am I missing something?

I just started learning CUDA programming. I was trundling through some simple CUDA C examples and everything was going swimmingly. Then! Suddenly! Thrust! I consider myself versed on C++ functors and was taken aback at the difference between CUDA C…

C++ keywords on CUDA C code

I am using CUDA to accelerate some parts of a C program. This program makes use of some C++ keywords as identifiers, so it doesn't compile as C++. Now that I changed it with CUDA, how can I compile it with NVCC? For instance, I get the…

Specify compiler NVCC uses to compile host-code

When running nvcc, it always uses the Visual C++ compiler (cl.exe). How can I make it use the GCC compiler? Setting the CC environment-variable to gcc didn't fix it. I also couldn't find any option for this in the executeables help-output.

Completely disable optimizations on NVCC

I'm trying to measure peak single-precision flops on my GPU, for that I'm modifying a PTX file to perform successive MAD instructions on registers. Unfortunately the compiler is removing all the code because it actually does nothing usefull since I…

nvc++ yields "error: expression must have a constant value" while g++ and clang++ do not

I am writing some software (C++20) in which many things are evaluated during compile time. Using g++ (version > 9) or clang++ (version > 10) the software compiles just fine on Ubuntu 22.04. However, when trying to compile it using nvc++ (version…

What's the NVCC warning token for " 'long double' is treated as 'double' in device code"?

In this question: How to disable a specific nvcc compiler warnings there's a link to a long "dictionary" mapping tokens to error messages, which seems to fit NVCC ... except it doesn't cover all warnings. Specifically, I want to suppress warning:…
