I'm having an issue using the Atomic Library in C++11, it's saying that I need to specify the flag std=c++11, but I don't know how to do that with I++ compiler. How do I correct this, since I need Compare and Swap behavior for my data structure?

Whereby when compiling my code with the command: g++ src/fpga_basic.cpp -march=x86-64 -std=c++11 -o test-x86_64 It compiles correctly and executes the behavior that is expected. However, when I t...

Hi Mayank,

Currently we do not support atomic instruction in HLS compiler.

For HLS , there is a series available in Intel FPGA channel in Youtube which describes pretty much in detail the steps and concepts.

Regarding support for 20.1 , the getting started guide can be useful

If any thing mentioned in the guide is not working out ,please let us know.

Thanks and Regards

Anil

    Hi Anil,

    Thanks for the response, so another few questions. What is currently the best way possible to run atomic instructions on the FPGA via intel services?

    ​

    Furthermore, I've been experiencing issues where is my FPGA (Intel Arria 10 Gx) is not being detected by the Quartus software (Version 20.1). However when I switch the version of Quartus to V18.1, the device becomes is recognised and ready for compilation.

    ​

    Could you explain why this may be the case?

    ​

    The device is connected via a PCIE into a data center. I'm running both software from Linux Ubuntu 18.04LTS.
