cl::sycl::exception #84

Can you please run this again using gdb to obtain a stack trace and post the trace here? |
|
Running the "accessors" sample should also have some more informative output, hopefully! |
|
run accessors got the error @DuncanMcBain |
|
this is gdb info @rodburns |
|
Thanks for sharing that. An exception is being thrown in the code. Can you put try and catch around the code and output the error shown in the exception? This should give the cl error code and will help to track down what the problem is. |

Hi @rodburns @DuncanMcBain . also I test my device by the code int main() { Here is the output |
|
@rodburns @DuncanMcBain Sorry for not reply at once ,I step in the queue define It seems that the error cause by the library here is the gdb detail Breakpoint 1, main () |

Hi @huoyushi, thanks for looking into this. The way to get the error code from the exception is to use the |

Hi @DuncanMcBain @rodburns Here is the detail of the exception: |

Hi @huoyushi, thanks for your excellent detective work! From the OpenCL specification, "CL_OUT_OF_HOST_MEMORY [is returned] if there is a failure to allocate resources required by the OpenCL implementation on the host". Bizarre as it sounds, how long has it been since you restarted your computer? Sometimes OpenCL implementations can leak objects over time, and eventually be unable to allocate even the most basic OpenCL objects. I can tell you that the function call that is failing is very simple, but I've been surprised before :) |

Thanks @mirh , that is a good point. We can sometimes detect this error and present a different message string, so I'll add an internal ticket to do so on a future ComputeCpp release... |
|
Oh, I forgot about that issue, and they never responded to us. Thanks for the reminder! |
I make this sdk with opencl1.2 .It can make successfully ,but When I run hello world ,I get this error
