device memory. I run about 500,000 threads in my program and each thread accesses 2000 chars. So I transfer 500,000 * 2000 = 1GB bytes at a time with the code err = cudaMemcpy (dev_database, adjusted_database[k], JOBS * 2000 * sizeof(char), cudaMemcpyHostToDevice); if(err != cudaSuccess) { printf("CUDA error: %s\n", cudaGetErrorString(err)); exit(EXIT_FAILURE); } In my kernel I also define three shared arrays //__shared__ char dev_query[200]; __shared__ float dev_scores[200*5]; __shared__ int dev_index[26]; and initialize them with if(threadIdx.x == 0) { //for(i = 0; i < 200; i++){ dev_query[i] = dev_query_constant[i]; } for(i = 0; i < 200 * 5; i++){ dev_scores[i] = dev_scores_constant[i]; } for(i = 0; i < 26; i++){ dev_index[i] = dev_index_constant[i]; } } __syncthreads(); If I run my program with the two lines commented my kernel returns strange values and when I copy the second chunk of the char array I get the error CUDA error: unspecified launch failure If I uncomment the lines in the code above everything works fine. If I copy smaller chunk

these errors can lead to application termination or unpredictable results.Table¬†3 lists reported errors, according to these platforms and settings:• Exception codes Lane Illegal Address and Lane Misaligned Address are detected using all supported SDK versions when CUDA memcheck is enabled, on supported Tesla and Fermi hardware.• All other CUDA errors are detected only for GPUs with sm_20 or higher (for example Fermi) running SDK 3.1 or higher. It is not necessary to enable CUDA memcheck to detect these errors.Table 3: CUDA Exception CodesException codeError PrecisionError ScopeDescriptionCUDA_EXCEPTION_0:“Device Unknown Exception”Not preciseGlobal error on the GPUAn application-caused global GPU error that does not match any of the listed error codes below.CUDA_EXCEPTION_1:“Lane Illegal Address”Precise (Requires memcheck on)Per lane/thread errorA thread has accessed an illegal (out of bounds) global address.CUDA_EXCEPTION_2:“Lane User Stack Overflow”PrecisePer lane/thread errorA thread has exceeded its stack memory limit.CUDA_EXCEPTION_3:“Device Hardware Stack Overflow”Not preciseGlobal error on the GPUThe application has triggered a global hardware stack overflow, usually caused by large amounts of divergence in the presence of function calls.CUDA_EXCEPTION_4:“Warp Illegal Instruction”Not preciseWarp errorA thread within a warp has executed an illegal instruction.CUDA_EXCEPTION_5:“Warp Out-of-range Address”Not preciseWarp errorA thread within a warp has accessed an address that is outside the valid range of local or shared memory regions.CUDA_EXCEPTION_6:“Warp Misaligned Address”Not preciseWarp errorA thread within a warp has accessed an incorrectly aligned address in the local or shared memory segments.CUDA_EXCEPTION_7:“Warp Invalid Address Space”Not preciseWarp errorA thread within a warp has executed an instruction that attempts to access a memory space not permitted for that instruction.CUDA_EXCEPTION_8:“Warp Invalid PC”Not preciseWarp errorA thread within a warp has advanced its PC beyond the 40-bit address space.CUDA_EXCEPTION_9:“Warp Hardware Stack Overflow”Not preciseWarp errorA thread within a warp
