Overview / Usage

The vector-multiplication is a simple program that multiplies Three large vectors of integers and verifies the results. This program is implemented using C and Data Parallel C (DPC++) languages for Intel(R) CPU and accelerators.

In this example, you can learn how to use the most basic code in C language that offloads computations to a GPU or an FPGA using the DPC language.

The basic DPC++ implementation explained in the code includes device selector, buffer, accessor, kernel, and command groups.

Methodology / Approach

Perform the following steps:

1. Build the vector-add program using:
   make all
2. Run the program using:
   make run
3. Clean the program using:
   make clean

1. Select Programs > Intel oneAPI 2021 > Intel oneAPI Command Prompt to launch a command window.
2. Build the program using the following nmake commands:nmake -f Makefile.win clean nmake -f Makefile.win nmake -f Makefile.win run

Perform the following steps:

1. Launch the Visual Studio* 2017.
2. Select the menu sequence File > Open > Project/Solution.
3. Locate the vector-add folder.
4. Select the vector-add.sln file.
5. Select the configuration 'Debug' or 'Release'
6. Select Project > Build menu option to build the selected configuration.
7. Select Debug > Start Without Debugging menu option to run the program.

Perform the following steps:

1. Clean the vector-add program using:
   make clean -f Makefile.fpga

2. Based on your requirements, you can perform the following:

   • Build and run for FPGA emulation using the following commands:

   • make fpga\_emu -f Makefile.fpga make run\_emu -f Makefile.fpga

   • Build and run for FPGA hardware.
     NOTE: The hardware compilation takes a long time to complete.

   • make hw -f Makefile.fpga make run\_hw -f Makefile.fpga

   • Generate static optimization reports for design analysis. Path to the reports is vector-add\_report.prj/reports/report.html

   • make report -f Makefile.fpga

Perform the following steps:

NOTE: On a Windows* system, you can only compile and run on the FPGA emulator. Generating an HTML optimization report and compiling and running on the FPGA hardware are not currently supported.

1. Select Programs > Intel oneAPI 2021 > Intel oneAPI Command Prompt to launch a command window.
2. Build the program using the following nmake commands:nmake -f Makefile.win.fpga clean nmake -f Makefile.win.fpga nmake -f Makefile.win.fpga run

Perform the following steps:

1. Launch the Visual Studio* 2017.
2. Select the menu sequence File > Open > Project/Solution.
3. Locate the vector-add folder.
4. Select the vector-add.sln file.
5. Select the configuration 'Debug-fpga' or 'Release-fpga' that have the necessary project settings already below:
   Under the 'Project Property' dialog:
   a. Select the DPC++ tab. b. In the General subtab, the Perform ahead of time compilation for the FPGA setting is set to Yes. c. In the Preprocessor subtab, the **Preprocessor Definitions" setting has FPGA_EMULATOR added. d. Close the dialog.
6. Select Project > Build menu option to build the selected configuration.
7. Select Debug > Start Without Debugging menu option to run the program. Don't go by the name Vector add its actually Vector Multiplication
