Using gpuArray to meet a error "An unexpected error occurred trying to launch a kernel"

Hi,

I used gpuArray with some functions such as permute and pagefun. A error ocurred: "An unexpected error occurred trying to launch a kernel. The CUDA error was: invalid configuration argument"

Here is my gpuDevice information:

 Name: 'GeForce GTX 1080'
                     Index: 1
         ComputeCapability: '6.1'
            SupportsDouble: 1
             DriverVersion: 10.2000
            ToolkitVersion: 10.1000
        MaxThreadsPerBlock: 1024
          MaxShmemPerBlock: 49152
        MaxThreadBlockSize: [1024 1024 64]
               MaxGridSize: [2.1475e+09 65535 65535]
                 SIMDWidth: 32
               TotalMemory: 8.5899e+09
           AvailableMemory: 6.7484e+09
       MultiprocessorCount: 20
              ClockRateKHz: 1759000
               ComputeMode: 'Default'
      GPUOverlapsTransfers: 1
    KernelExecutionTimeout: 1
          CanMapHostMemory: 1
           DeviceSupported: 1
            DeviceSelected: 1

When the error ocurred, the error could be solved by re-run the same code again without changing anything. I really don't know how to fix it.

It sounds like you did fix it . As you say, when you re-ran, it worked.

[Y.Yang]

But it only works for re-running that specific line. If I re-run the entire m file, it will be forced to terminate it by the error.

Hey Y.Yang - were you able to find a fix for this? I'm running into exactly this issue. Thanks

[Y.Yang]

No. I believe it is a bug, not coding error.
