Re: DPC++ Flags -> Quartus
aoc.pl is called by dpcpp (there is nothing irregular about the compilation process); you can see the tree above: dpcpp->clang->perl. The user specified Xsparallel is being passed down but the Intel tools are inserting a duplicate, which is likely causing the user value to be overwritten.1.6KViews0likes0CommentsRe: DPC++ Flags -> Quartus
This is the process tree for the aoc.pl perl script. The user run line is: dpcpp -Xsparallel=12 -I../intel/2021.1.0.2659/dev-utilities/2021.1.1/include -fintelfpga -Xshardware -Xsdaz -Xsrounding=faithful -Xsparallel=2 -Xsseed=4 -Xsboard=s10:p520_max_sg280l -DOUTER_UNROLL=2 -DINNER_UNROLL=64 -DOUTER_UNROLL_POW2=2 Everything below that is the dpcpp -> quartus toolchain, which is invoked automatically (user has no control). ~Clay1.7KViews0likes0CommentsDPC++ Flags -> Quartus
When using dpcpp to compile for an FPGA target, is there a way to control the number of threads that the Quartus tools can use? sh,80458 -c cd ../oneAPI-samples/DirectProgramming/DPC++FPGA/ReferenceDesigns/crr/build/src && ../intel/2021.1.0.2659/compiler/2021.1.1/linux/bin/dpcpp -Xsparallel=12 -I../intel/2021.1.0.2659/dev-utilities/2021.1.1/include -fintelfpga -Xshardware -Xsdaz -Xsrounding=faithful -Xsparallel=2 -Xsseed=4 -Xsboard=s10:p520_max_sg280l -DOUTER_UNROLL=2 -DINNER_UNROLL=64 -DOUTER_UNROLL_POW2=2 crr_fpga.o -o ../oneAPI-samples/DirectProgramming/DPC++FPGA/ReferenceDesigns/crr/build/crr.fpga └─dpcpp,80459 -I../intel/2021.1.0.2659/dev-utilities/2021.1.1/include -fintelfpga -Xshardware -Xsdaz -Xsrounding=faithful -Xsparallel=2 -Xsseed=4 -Xsboard=s10:p520_max_sg280l -DOUTER_UNROLL=2 -DINNER_UNROLL=64 -DOUTER_UNROLL_POW2=2 crr_fpga.o -o ../oneAPI-samples/DirectProgramming/DPC++FPGA/ReferenceDesigns/crr/build/crr.fpga └─clang++,80460 --dpcpp -fsycl -I../intel/2021.1.0.2659/dev-utilities/2021.1.1/include -fintelfpga -Xshardware -Xsdaz -Xsrounding=faithful -Xsparallel=2 -Xsseed=4 -Xsboard=s10:p520_max_sg280l -DOUTER_UNROLL=2 -DINNER_UNROLL=64 -DOUTER_UNROLL_POW2=2 crr_fpga.o -o ../oneAPI-samples/DirectProgramming/DPC++FPGA/ReferenceDesigns/crr/build/crr.fpga └─perl,80472 ../intel/2021.1.0.2659/compiler/2021.1.1/linux/lib/oclfpga/share/lib/perl/acl/aoc.pl -o /tmp/crr_fpga-32e90b.aocx /tmp/crr_fpga-54488f.spv -sycl -dep-files=/tmp/crr_fpga-2de1d6.d -output-report-folder=../oneAPI-samples/DirectProgramming/DPC++FPGA/ReferenceDesigns/crr/build/crr.prj -g -hardware -daz -rounding=faithful -parallel=2 -seed=4 -board=s10:p520_max_sg280l Passing -Xsparallel=<x> is overridden.1.9KViews0likes7CommentsRe: dpcpp Compilation Time - Number of Threads per Quartus Process
