Question

我是SYCL / OpenCL / GPGPU的新手。我正在尝试构建并运行常量添加程序的示例代码，

#include <iostream>
#include <array>
#include <algorithm>

#include <CL/sycl.hpp>

namespace sycl = cl::sycl;

//<<Define ConstantAdder>>
template<typename T, typename Acc, size_t N>
class ConstantAdder {
public:
  ConstantAdder(Acc accessor, T val)
    : accessor(accessor)
    , val(val) {}

  void operator() () {
    for (size_t i = 0; i < N; i++) {
      accessor[i] += val;
    }
  }

private:
  Acc accessor;
  const T val;
};

int main(int, char**) {
  std::array<int, 4> vals = {{ 1, 2, 3, 4 }};

  sycl::queue queue(sycl::cpu_selector{});
  std::cout << "Running on "
      << queue.get_device().get_info<sycl::info::device::name>()
      << "\n";

  {
    sycl::buffer<int, 1> buf(vals.data(), sycl::range<1>(4));
    queue.submit([&] (sycl::handler& cgh) {
    auto acc = buf.get_access<sycl::access::mode::read_write>(cgh);

    cgh.single_task(ConstantAdder<int, decltype(acc), 4>(acc, 1));
      } );
  }

  std::for_each(vals.begin(), vals.end(), [] (int i) { std::cout << i << " "; } );
  std::cout << std::endl;

  return 0;
}

我正在使用

构建此代码

$ g ++ constantAdder_backup.cpp -g -std = c ++ 11 -o constantAdder -I / usr / local / computecpp / include -I / usr / include / -L / usr / local / computecpp / lib -lComputeCpp -L / usr / lib / x86_64-linux-gnu -lOpenCL

并收到错误

什么是

在抛出一个实例后终止调用 “CL :: sycl ::详细:: exception_implementation≤（CL :: sycl ::详细:: exception_types）9， CL :: sycl ::详细:: exception_implementation≤（CL :: sycl ::详细:: exception_types）6， CL :: sycl ::例外＆GT; ＆GT;”中止（核心倾倒）错误意味着？我怎样才能解决这个问题？请帮帮我。

P.S。系统硬件

P.S。 我已更新代码以了解我正在运行代码的设备。

修改片段是

sycl::queue queue(sycl::cpu_selector{});

std::cout << "Running on "
    << queue.get_device().get_info<sycl::info::device::name>()
    << "\n";

现在我正在使用cpu::selector（不是nvidia硬件），并打印设备。它清楚地表明它正在Intel(R) Core(TM) i7-4790 CPU @ 3.60GHz上运行。

的输出

couputecpp_info

显示

Device is supported                     : YES - Tested internally by Codeplay Software Ltd

但是，它仍然显示与

相同的错误

在抛出一个实例后终止调用 “CL :: sycl ::详细:: exception_implementation≤（CL :: sycl ::详细:: exception_types）9， CL :: sycl ::详细:: exception_implementation≤（CL :: sycl ::详细:: exception_types）6， CL :: sycl ::例外＆GT; ＆GT;” 中止（核心倾销）

Answer 1

有一种类型cl::sycl::detail::exception_implementation<(cl::sycl::detail::exception_types)9, cl::sycl::detail::exception_implementation<(cl::sycl::detail::exception_types)6, cl::sycl::exception> >被抛出但未被捕获的例外。

要查看异常的详细信息，请在main中添加try catch或在调试器中运行代码。 e.g：

int main(int, char**) {
  try
  {
     /*your code here*/
  }
  catch (std::exception& ex)
  {
    std::cerr << "exception caught: " << ex.what() << std::endl;
    return 1;
  }
  return 0;
}

Answer 2

构建代码时，您没有使用SYCL编译器。可以使用以下命令执行此操作。

/bin/compute++ constantAdder_backup.cpp -g -std=c++11 -o constantAdder -I /usr/local/computecpp/include -I/usr/include/ -L /usr/local/computecpp/lib -lComputeCpp -L /usr/lib/x86_64-linux-gnu -lOpenCL

您还需要确保在执行输出时将LD_LIBRARY_PATH设置为指向ComputeCpp安装的lib文件夹。

Answer 3

我在安装cuda 9.2时注意到了相同的错误，请尝试卸载cuda并再次运行您的代码

在抛出'cl :: sycl :: detail :: exception_implementation＆lt;（cl :: sycl :: detail :: exception_types）9＆gt;'的实例后调用终止
