Hi,
Please follow the below steps to run matrix_mul in the FPGA emulator(in oneAPI DevCloud).
Step 1: Under matrix_multiplication folder:
- Create build_fpga_emu.sh
#!/bin/bash #PBS -l nodes=1:fpga_compile:ppn=2 #PBS -d . source /opt/intel/oneapi/setvars.sh > /dev/null 2>&1 echo echo start: $(date "+%y/%m/%d %H:%M:%S.%3N") echo make fpga_emu -f Makefile.fpga echo echo stop: $(date "+%y/%m/%d %H:%M:%S.%3N") echo - Create run_fpga_emu.sh.
#!/bin/bash
#PBS -l nodes=1:fpga_compile:ppn=2
#PBS -d .
source /opt/intel/oneapi/setvars.sh > /dev/null 2>&1
echo
echo start: $(date "+%y/%m/%d %H:%M:%S.%3N")
echo
make run_emu -f Makefile.fpga
echo
echo end: $(date "+%y/%m/%d %H:%M:%S.%3N")
echo
- Create Makefile.fpga and paste the contents as below:
CXX := dpcpp
CXXFLAGS = -O2 -g -std=c++17
SRC := src/matrix_mul_dpcpp.cpp
.PHONY: fpga_emu run_emu clean
fpga_emu: matrix_mul_dpcpp.fpga_emu
report: matrix_mul_dpcpp.a
matrix_mul_dpcpp.fpga_emu: $(SRC)
$(CXX) $(CXXFLAGS) -fintelfpga $^ -o $@ -DFPGA_EMULATOR=1
a.o: $(SRC)
$(CXX) $(CXXFLAGS) -fintelfpga -c $^ -o $@ -DFPGA=1
run_emu: matrix_mul_dpcpp.fpga_emu
./matrix_mul_dpcpp.fpga_emu
dev.o: $(SRC)
$(CXX) $(CXXFLAGS) -fintelfpga -c $^ -o $@ -DFPGA=1
clean:
rm -rf *.o *.d *.out *.mon *.emu *.aocr *.aoco *.prj *.fpga_emu *.fpga_emu matrix_mul_dpcpp.fpga *.a
Step 2: Navigate to the src folder in matrix_mul
Step 3: Edit the matrix_mul_dpcpp.cpp file as below:
- Add in the header :
#include <sycl/ext/intel/fpga_extensions.hpp>
- Add the below under main() :
#if FPGA_EMULATOR
// DPC++ extension: FPGA emulator selector on systems without FPGA card.
ext::intel::fpga_emulator_selector d_selector;
#elif FPGA
// DPC++ extension: FPGA selector on systems with FPGA card.
ext::intel::fpga_selector d_selector;
#else
// The default device selector will select the most performant device.
default_selector d_selector;
#endif
After editing and creating the above files run the below commands:
qsub -l nodes=1:fpga_compile:ppn=2 -d . build_fpga_emu.sh
qsub -l nodes=1:fpga_compile:ppn=2 -d . run_fpga_emu.sh
The result will be generated. Please try and let us know if you need any clarifications.
If this resolves your issue, make sure to accept this as a solution. This would help others with similar issues. Thank you!

Tried all these steps
Included Makefile.fpga
I think Fpga is not getting detected. FPGA_Emulator and FPGA are in red color when .cpp file is edited.
So after build
and after run nothing is happening
No output.. No error..
Is there anything else to do initially before all these steps..?
Hi,
Sharing the screenshot of the matrix_mul_dpcpp.cpp file, where you need to make the changes.
Are you saying about the highlighted part in the code? If yes, the red highlight shouldn't be a problem.
Make sure the spaces and tabs are given correctly in all the files.
If issue still exist, please send a screenshot/content of the error files.

Hi,
I am attaching the screenshot and files. Please check and let us know if you are able to do the execution.
