cannot run on fpga hardware - cannot run on fpga hardware Hello, I've recently noticed that programs previously running on the fpga hardware are no longer working. I've also tried to recompile but I get the same problem. Here's the message I receive for arria 10 oneAPI. Error enumerating AFCs: not found Error enumerating AFCs: not found Error enumerating AFCs: not found Error enumerating AFCs: not found Segmentation fault Do you have any suggestions? Thank you for your help. Replies: Re: cannot run on fpga hardware hello Is it working fine , I am still getting errors while using Opencl kernel on FPGA it mostly gives segmentation error 139 Replies: Re: cannot run on fpga hardware is it working now i am still facing such issues Replies: Re: cannot run on fpga hardware are you people still facing the issue ,i am getting segmentation fault 139 error always Replies: Re: cannot run on fpga hardware Thanks You are right. It now works for me again. I think the problem was that the qsub was not choosing nodes correctly. The nodes it chooses now are different and have the FPGA hardware installed. Regards Marcus Replies: Re: cannot run on fpga hardware Hi. Now it seems to work. I didn't make any change. Replies: Re: cannot run on fpga hardware Hi, no, I still have the same problem unfortunately. Replies: Re: cannot run on fpga hardware I've had exactly the same problem and symptoms for the last few weeks. Programs compiled for FPGA hardware no longer run on fpga nodes. Have you found a solution? Thanks Marcus Replies: Re: cannot run on fpga hardware Hello and thank you for your reply. Below you can find the Makefile that I am using to compile and execute.

I do not understand why, but everything was working until about a week ago. Thanks for you help. Best regards. PS: the commands 1), 2) ... 5) are executed through qsub -l nodes=1:fpga_compile:ppn=2 -d . job1.sh or qsub -l nodes=1:fpga_runtime:ppn=2 -d . job2.sh and the file job.sh look like #!/bin/bash cd /home/my_directory source /opt/intel/inteloneapi/setvars.sh make run_hw Replies: Re: cannot run on fpga hardware Hi @scali ., Thank you for posting in Intel community forum and hope this message find you well. Can you share what command are being executed to compile the design? If you are trying to run simulation, please do refer to the related troubleshooting here . Please do let us know if that helps.
