系统软件层

该程序使用 SYCL 获取设备信息,并提取设备的名称、最大计算单元数和全局内存大小等信息,并将这些信息打印到控制台。

示例代码:

#include <CL/sycl.hpp> #include <iostream> int main() {    try {        // sycl::default_selector_v        sycl::default_selector selector;        sycl::queue queue(selector);        // device        sycl::device device = queue.get_device();        std::cout << "Device Name: " << device.get_info<sycl::info::device::name>() << std::endl;        std::cout << "Device Vendor: " << device.get_info<sycl::info::device::vendor>() << std::endl;        std::cout << "Max Compute Units: " << device.get_info<sycl::info::device::max_compute_units>() << std::endl;        std::cout << "Global Memory Size: " << device.get_info<sycl::info::device::global_mem_size>() / (1024 * 1024) << " MB" << std::endl;   } catch (const sycl::exception& e) {        std::cerr << "SYCL exception caught: " << e.what() << std::endl;        return 1;   }    return 0; }

结果:

Device Name: NVIDIA GeForce RTX 2080 Ti Device Vendor: NVIDIA Corporation Max Compute Units: 68 Global Memory Size: 11002 MB
