Cuda Error Invalid Configuration Argument
only takes a minute: Sign up cuda “invalid argument” error on second kernel up vote 0 down vote favorite I got a problem with kernel launches. I had a program using one big kernel. Now I needed to split it into two due to synchronization issues. The first kernel does some init stuff and gets passed a subset of the arguments
Cudathreadsynchronize
passed to the second kernel. Running only the first kernel works fine. Running only the second kernels fails while executing it, due to missing initialization but the kernel itself is started. Running both in a row lets the second kernel fail with an "invalid argument" error. I will provide code if necessary but can't figure out right now how it might help. Thanks in advance. EDIT: here the requested launch code: void DeviceManager::integrate(){ assert(hostArgs->neighborhoodsSize > 0); size_t maxBlockSize; size_t blocks; size_t threadsPerBlock; // init patch kernel maxBlockSize = 64; blocks = (hostArgs->patchesSize /maxBlockSize); if(0 != hostArgs->patchesSize % maxBlockSize){ blocks++; } threadsPerBlock = maxBlockSize; std::cout << "blocks: " << blocks << ", threadsPerBlock: " << threadsPerBlock << std::endl; initPatchKernel

I've declared a device __constant__ variable at the top section of my main.cu file, outside any function. http://stackoverflow.com/questions/9676441/cudas-cudamemcpytosymbol-throws-invalid-argument-error __device__ __constant__ int* dic; I also have a host variable, flatDic, that's malloc'ed the following way, inside main(): int* flatDic = (int *)malloc(num_codewords*(bSizeY*bSizeX)*sizeof(int)); Then I try to copy the contents of flatDic into dic by doing so, also in main(): cudaMemcpyToSymbol(dic, flatDic, num_codewords*(bSizeY*bSizeX)*sizeof(int)); This cudaMemcpyToSymbol() call it's line 386 of main.cu, and it's where the aforementioned error is thrown. What I've tried Here's what I've tried so far to solve the problem: I've tried the all of the following, returning always the same error: cudaMemcpyToSymbol(dic, &flatDic, num_codewords*(bSizeY*bSizeX)*sizeof(int)); cudaMemcpyToSymbol(dic, flatDic, num_codewords*(bSizeY*bSizeX)*sizeof(int)); cudaMemcpyToSymbol(dic, &flatDic, num_codewords*(bSizeY*bSizeX)*sizeof(int), 0, cudaMemcpyHostToDevice); cudaMemcpyToSymbol(dic, flatDic, num_codewords*(bSizeY*bSizeX)*sizeof(int), 0, cudaMemcpyHostToDevice); I've also tried to cudaMalloc() the dic variable, before calling cudaMemcpyToSymbol(). No errors are thrown in cudaMalloc(), but cudaMemcpyToSymbol() error persists. cudaMalloc((void **) &dic, num_codewords*(bSizeY*bSizeX)*sizeof(int)); I've also search extensively thorough the web, documentation, forums, examples, etc, all to no avail. Does anyone see anything wrong with my code?

I tried to take a simple practice to help me to get familiar to it. I coded a little program "Finding Prime Numbers". It almost done, but there is a problem which I cannot solve it. I found that the maximum number which I can find is 1027. If I input more than 1027, I will get the error message: getPrimeKernel launch failed!!: invalid configuration argument findPrimeWithCuda failed!! Where should cuda error file I adjust my code? Thank you. Here is my code: #include "cuda_runtime.h" #include "device_launch_parameters.h" #include
