Thanks! 0 Comments Show all comments Log In to answer or comment on this question. Is there a way to verify its set value (8 or 32) so that we are sure that we are in fact using all 32 connections provided? Eine freundliche, aus vielen Experten bestehende Community, unterstützt Dich hier mit Herz und Leidenschaft bei der Lösung von Problemen mit der Programmierung in verschiedenen Programmiersprachen. static int CUDA_ERROR_NOT_READY This indicates that asynchronous operations issued previously have not completed yet.

I just increased it to 64 streams which (does not make sense but) worked as well. CUDA_ERROR_INVALID_IMAGE This indicates that the device kernel image is invalid. Actually, whether or not it works is beyond my control. See Also:Constant Field Values CUDA_ERROR_OUT_OF_MEMORY public static finalint CUDA_ERROR_OUT_OF_MEMORY The API call failed because it was unable to allocate enough memory to perform the requested operation. https://www.mathworks.com/matlabcentral/answers/34052-cuda_error_launch_failed-problem

Is there any dependency between the number of streams and shared memory resource allocation? See Also:Constant Field Values CUDA_ERROR_ILLEGAL_INSTRUCTION public static finalint CUDA_ERROR_ILLEGAL_INSTRUCTION While executing a kernel, the device encountered an illegal instruction. See Also:Constant Field Values CUDA_ERROR_INVALID_GRAPHICS_CONTEXT public static finalint CUDA_ERROR_INVALID_GRAPHICS_CONTEXT This indicates an error with OpenGL or DirectX context. In scenario 2, I have one GK110 GPU and multiple CPU threads (say max 32) accessing that device with different contexts.

You signed out in another tab or window. All existing device memory allocations from this context are invalid and must be reconstructed if the program is to continue using CUDA. It is no longer an error to attempt to enable/disable the profiling via ::cuProfilerStart or ::cuProfilerStop without initialization.

CUDA_ERROR_NOT_MAPPED This indicates that a resource is not mapped. The problem is, I just don't know what.Here's my kernel:#include #include #include /* this is directly from Minka's lightspeed toolbox*/ __global__ void digamma(double *y) { int idx_x = Something like Java Code: public static void main (String[] args) { Map env = System.getenv(); System.out.println("CUDA_DEVICE_MAX_CONNECTIONS : "+env.get(CUDA_DEVICE_MAX_CONNECTIONS)); ... news This error usually indicates that the user has attempted to pass too many arguments to the device kernel, or the kernel launch specifies too many threads for the kernel's register count.

Or is the technology capacity still limited to one context per GPU at any particular time instance? 2.

(LogOut/Change) You are cuda-memcheck shows that there are invalid shared memory writes: $ cuda-memcheck ./launch_failure_kernel ========= CUDA-MEMCHECK 1. static int CUDA_ERROR_INVALID_VALUE This indicates that one or more of the parameters passed to the API call is not within an acceptable range of values.

Examples of symbols are global/constant variable names, texture names, and surface names. https://github.com/vlfeat/matconvnet/issues/332 auto x0 = vex::permutation(idx )(X); auto x1 = vex::permutation(idx + N )(X); auto x2 = vex::permutation(idx + N * 2)(X); // write individual components: x0 = 1; x1 = 2; x2 See Also:Constant Field Values CUDA_ERROR_PEER_ACCESS_UNSUPPORTED public static finalint CUDA_ERROR_PEER_ACCESS_UNSUPPORTED This indicates that peer access is not supported across the given devices.

CUDA_ERROR_DEINITIALIZED This indicates that the CUDA driver is in the process of shutting down. Reload to refresh your session. it's giving this error immediately.did you solve it? See Also:Constant Field Values CUDA_ERROR_NOT_PERMITTED public static finalint CUDA_ERROR_NOT_PERMITTED This error indicates that the attempted operation is not permitted.

static int CUDA_ERROR_SHARED_OBJECT_INIT_FAILED This indicates that initialization of a shared object failed. template device_vector(const command_queue &q, size_t n, const H *host = 0, mem_flags flags = MEM_READ_WRITE) : n(n) { (void)flags; if (n) { q.context().set_current(); CUdeviceptr ptr; cuda_check( cuMemAlloc(&ptr, n * See Also:Constant Field Values CUDA_ERROR_PROFILER_NOT_INITIALIZED public static finalint CUDA_ERROR_PROFILER_NOT_INITIALIZED Deprecated.This error return is deprecated as of CUDA 5.0. However, the current version of the Programming Guide, in the section about concurrent kernel execution, it states Zitat von CUDA Programming Guide A kernel from one CUDA context cannot execute concurrently

However, as far as I can determine, it's not the kernel which cause the problem here – although it takes a long time to compile, it executes ok – but rather The CUDA error was: CUDA_ERROR_LAUNCH_FAILED Error in dagnn.Pooling/backward (line 18) derInputs{1} = vl_nnpool(inputs{1}, self.poolSize, derOutputs{1}, ...

Rinse. The machine has 4 GTX Titan cards being used to develop our multi-GPU based application. my matlab won't even work for a short period of time. Error in dagnn.DagNN/eval (line 99) obj.layers(l).block.backwardAdvanced(obj.layers(l)) ; Error in cnn_train_dag>process_epoch (line 186) net.eval(inputs, opts.derOutputs) ; Error in cnn_train_dag (line 84) stats.train(epoch) = process_epoch(net, state, opts, 'train') ; This error occurs only

This indicates profiler has already been stopped and probably cuProfilerStop() is incorrectly called. The GPU usage hovers around 5.5GB/ 11.5GB on a K-40 with cuda 6.5. Most of my work involves rendering a model in OpenGL, reading the pixels back into main memory with glReadPixels(), and doing image analysis on them. I think there is a way of running the command line profiler and loading its output into the visual profiler (as a CSV file), but I'll have to investigate further whether

The context cannot be used, so it must be destroyed (and a new one should be created). Error 700 could mean e.g. ddemidov closed this Dec 18, 2013 Sign up for free to join this conversation on GitHub. See Also:Constant Field Values CUDA_ERROR_NOT_INITIALIZED public static finalint CUDA_ERROR_NOT_INITIALIZED This indicates that the CUDA driver has not been initialized with ::cuInit() or that initialization has failed.

See Also:Constant Field Values CUDA_ERROR_INVALID_CONTEXT public static finalint CUDA_ERROR_INVALID_CONTEXT This most frequently indicates that there is no context bound to the current thread. Can you check if this is true (e.g. Is profiler even supported for these CUDA and JCUDA versions? See Also:Constant Field Values CUDA_ERROR_ALREADY_ACQUIRED public static finalint CUDA_ERROR_ALREADY_ACQUIRED This indicates that a resource has already been acquired.

static int CUDA_ERROR_INVALID_ADDRESS_SPACE While executing a kernel, the device encountered an instruction which can only operate on memory locations in certain address spaces (global, shared, or local), but was supplied All existing device memory allocations from this context are invalid and must be reconstructed if the program is to continue using CUDA.

This caused me to start a thread about this at the NVIDIA forum, but there was no response (...). static int CUDA_ERROR_OUT_OF_MEMORY The API call failed because it was unable to allocate enough memory to perform the requested operation. On both cards, this kernel runs in blocks of 8 threads with 25792 bytes of shared memory per block; the maximum shared memory per block on these cards in 48kb. The information log was: The error log was: The CUDA error code was: CUDA_ERROR_LAUNCH_FAILED.

See Also:Constant Field Values CUDA_ERROR_INVALID_HANDLE public static finalint CUDA_ERROR_INVALID_HANDLE This indicates that a resource handle passed to the API call was not valid. CUDA_ERROR_LAUNCH_TIMEOUT This indicates that the device kernel took too long to execute. I have two alternatives for convenient access to the components of such vector (you will need commit ac82646 for both to work). static int CUDA_ERROR_LAUNCH_TIMEOUT This indicates that the device kernel took too long to execute.
