Re: install oneAPI on RHEL OS with D5050 card
Hi, BB, Yes, -gcc-toolchain was specified in the compiling process, but it didn't seem to work. We figured out that oneAPI add-on was not properly installed. We are now working on a fresh installation and will keep you posted for the result. Thanks for the follow up. Bei2.8KViews0likes0CommentsRe: install oneAPI on RHEL OS with D5050 card
Hi, BoonBengT_Intel, Thanks for the suggestion. Here is the version numbers for gcc and cmake. $ gcc --version gcc (GCC) 7.4.0 Copyright (C) 2017 Free Software Foundation, Inc.

The compiling process seems pick up the cc compiler which points to GNU 4.8.5 instead of gcc compiler which points to GNU 7.4.0. Thanks Bei2.9KViews0likes0Commentsinstall oneAPI on RHEL OS with D5050 card
We have a D5050 card with Springdale Linux 7.9, a custom red-hat based distribution. We then follow the instruction here to install the required packages for oneAPI. However, we had the following error message in compiling oneAPI sample code. Can you please advise? These are what we did. 1. downloaded the oneAPI sample code 2021.3.0 here at: https://github.com/oneapi-src/oneAPI-samples/releases/tag/2021.3.0 2. "source /opt/intel/oneapi/setvars.sh” 3.

Thanks Bei2.9KViews0likes8CommentsRe: Compiling error: Couldn't open *.bc.xml for read!
Now I am able to compile it successfully w/o the -o option. Here are the steps I followed: 1. aoc -c kernel1.cl kernel2.cl 2. aoc -rtl kernel1.cl kernel2.cl 3. aoc kernel2.aocr It seems that -o option in the second step only renames the directory, but not the required file names within it (e.g., *.bc.xml etc). Now the question is how to use the -o option correctly for aoc -rtl so that both directory and file names are renamed? Thanks1.5KViews0likes0CommentsCompiling error: Couldn't open *.bc.xml for read!
I was trying to compile multiple kernel files. Here are the steps I followed: 1. aoc -c kernel1.cl kernel2.cl 2. aoc -rtl -o allKernels.aocr kernel1.aoco kernel2.aoco 3. aoc allKernels.aocr The first 2 steps were successfully. The compiling for the third step takes a long time, but returned the following error message at the end: Error: Coundn't open allKernels.bc.xml for read! In the allKernels folder generated from the second step, I could see kerenl2.bc.xml file, but not allKernels.bc.xml. My feeling is the way I compile multiple kernel files in a single *.aocx file as above might not be correct. I am using Quartus 19.2. Can you please advise?

I am wondering if anyone knows an efficient parallel prefix sum OpenCL implementation for FPGA. I am currently using the one at CLPP , but it is extremely slow. I guess it makes sense since it was developed earlier for GPU. Anyone knows an open source parallel prefix sum optimized for FPGA? Thanks2.6KViews0likes2CommentsRe: Error in using emulator mode with SDK 20.1 for hello_world example
Hi, Anil, I've tried this by replacing the current Altera.icd file at /etc/OpenCL/vendors/ with the one at .../19.4/hld/Altera.icd. It is still the same error message during running:Context callback: Malformed program binary: missing .acl.board section Thanks Bei3.1KViews0likes1Commenterror in compiling with -fast-compile option on pac_s10_dc
