Error messages while following vector-add tutorial

[JasperW99]

I tried to follow the vector-add on FPGA tutorial (https://github.com/intel/FPGA-Devcloud/tree/master/main/QuickStartGuides/OneAPI_Program_PAC_Quickstart/Arria%2010 ), but I keep running into error messages when I try to execute it on the hardware. The output I get is 

:: WARNING: setvars.sh has already been run. Skipping re-execution.
   To force a re-execution of setvars.sh, use the '--force' option.
   Using '--force' can result in excessive use of your environment variables.

Error enumerating AFCs: not found
Error enumerating AFCs: not found
Error enumerating AFCs: not found
Makefile.fpga:41: recipe for target 'run_hw' failed
make: *** [run_hw] Segmentation fault

I compiled it using

qsub -l nodes=1:fpga_compile:ppn=2 build_hw.sh -d .

and I tried to run it on a node with an Arria 10 FPGA using 

qsub -l nodes=1:fpga_runtime:arria10:ppn=2 run_hw.sh -d .

 As source for the run_hw.sh I used:

#!/bin/bash
source /opt/intel/inteloneapi/setvars.sh
make run_hw -f Makefile.fpga

And for the build_hw.sh I used:

#!/bin/bash
source /opt/intel/inteloneapi/setvars.sh
make hw -f Makefile.fpga

Now is my question here, is there something wrong with my FPGA compilation flow, or does this problem have another cause? If you are able to run this tutorial succesfully, I would like to hear it too.

P.S. I hope I placed this under the right category

Hi @JasperW99,

Thank you for posting in Intel community forum and hope this message find you well.
May I know which nodes are you login into in the DevCloud?
In which steps in the tutorial mention that you are having the error?
The mention vector-add repo might been deprecated, you may refer to the one here with the latest updates and steps.

Best Wishes

Hi @BoonBengT_Intel,

Thanks for replying to my problem. I downloaded the vector-add repo again from your link, but I ran into the same problem. Compiling for the hardware goes without trouble, there are no warnings or errors. However, when I try to execute it onto the FPGA I get various errors. 

I invoke the execution with the following command:

qsub -l nodes=1:fpga_runtime:arria10:ppn=2 -d . run.sh

The run.sh script:

#!/bin/bash
source /opt/intel/inteloneapi/setvars.sh
./vector-add-buffers.fpga

The script executed on the s001-n083 node and gave the following output:

Thanks in advance.

Hi @JasperW99,

Apologies for the delayed in response, may I know which node are you compiling the design at?
Notice that some other customers seems to have the similar problem last week, and are able to compile successfully this week, might be due to environment instabilities.
Please do try again and let us know if it works.

Hi @BoonBengT_Intel ,

Apologies for the delayed response, everything works again now. It probably had to do with the environment instabilities you mentioned.

Kind regards,
