在Intel DevCloud的FPGA上的结果

Question

我正在通过以下链接学习OneAPI OpenCL FPGA在Intel DevCloud中的实现(https://github.com/intel/FPGA-Devcloud/tree/master/main/QuickStartGuides/OpenCL_Program_PAC_Quicksta...)。我在Windows操作系统上使用MobaXterm。这是一个简单的"Hello World"示例。我完成了每一步，一切都很顺利。它还表示，在终端结束时"内核执行已完成"。现在，我想看看"你好世界"的结果。如何在Intel DevCloud中看到它？非常感谢。

我不确定。难道我不希望在Intel DevCloud的FPGA上看到"Hello World"文本吗？请引导我。

Answer 1

您提供的链接似乎不完整。如果你指的是这个链接：使用Stratix 10 Devstack 2.0.1版本在FPGA devcloud上进行Stratix 10PAC:OpenCL编译和编程，请按照GitHub存储库中README文件中提到的步骤进行操作。

在执行步骤3.4时，您将得到以下输出：

uXXXX@s005-n006:~/S10_OPENCL_AFU/hello_world$ aocl program acl0 bin/hello_world.aocx
aocl program: Running program from /opt/intel/2.0.1/inteldevstack/d5005_ias_2_0_1_b237/opencl/opencl_bsp/linux64/libexec
Program succeed.
