Error enumerating AFCs: no driver available

Dear admin,

When I connect to DevCloud for FPGA and login in, I want to run t2s performance benchmark: https://github.com/IntelLabs/t2sp/tree/master/t2s/tests/performance/. When I try to run the script

./test.sh (devcloud|local) (gemm|conv|capsule) (a10|gen9) (tiny|large) (hw|emulator)

or offload the bitstream by myself: 

aocl program acl0 a.aocx

it went wrong like this:

Error enumerating AFCs: no driver available

Error enumerating AFCs: no driver available

Error parsing device name '????'

Error parsing device name '????'

Error enumerating AFCs: no driver available

Error enumerating AFCs: no driver available

Error enumerating AFCs: no driver available

However, the above two options work fine for me last week. So it would be great if someone can help me to confirm if this is a devcloud's problem, or I miss something important?

Thanks,
Jiyuan Wang

    Hi @JiyuanWang,

    Thank you for posting in Intel community forum and hope all is well.
    My guess is that it might be devcloud nodes instabilities, as mention previously it was working.

    Just to clarify this is the steps you have followed right?
    And do you know which nodes that you are connected to when it was working and not?
    Hope to hear from you soon.

    Best Wishes

      Hi BB,

      Yes, I think I have followed right since I can successfully run the t2s benchmark last week.

      I tried s001-n137, s005-n001, s005-n002, and all of them reported the same error message.

      Thanks for the reply!

    Hello,

    was this issue ever solved? I am having the same issue on devcloud nodes with Arria 10 OneAPI. Please let me know when possible. Thank you.

    Hi @JiyuanWang,

    Noted on the inputs on the nodes mention, we are currently looking into the platform itself to further checked.
    Apologies for the inconvenient cause, but we will get back to you for any updates as soon as possible
    Thank you for the patients.

      Well, actually seems it has been solved yesterday

      But for the last two weeks, such errors did happen.

    Great! Good to know that it is working now, there are some platform anomaly from our end and we apologies for the inconvenient and are looking for improvement at the same time, with no further clarification on this thread, it will be transitioned to community support for further help on doubts in this thread, where we will no longer monitor this thread.
