DevCloud: Unable to compile for FPGAs (aoc: Quartus is not on the path!)

Hi there, I noticed a change in the DevCloud environment and now I can no longer compile for the hardware, but only for the emulator.: u34356@login-2:~/oneAPI/Code/mine/fdct$ qsub -I -l nodes=1:fp...

The script suggested above (source /data/intel_fpga/devcloudLoginToolSetup.sh) is usable if you are in interactive mode because it presents you an interactive menu (via tools_setup), but is not useful in batch mode. Additionally, as noted above, the options it gives you do not help because 17.1.1 is not in the options list. The current oneAPI installation that targets Intel Arria 10 FPGA requires version 17.1.1.

As a workaround, you can add additional commands to your build_fpga_hw.sh script. This is explicitly setting up the necessary Quartus environment variables. Here is the full .sh file:

#!/bin/bash
source /opt/intel/inteloneapi/setvars.sh
 
ACDS_ROOT="/glob/development-tools/oneapi/inteloneapi/intelfpgadpcpp/latest/QuartusPrimePro/17.1.1/"
MODELSIM_ROOT="$ACDS_ROOT/modelsim_ae/linuxaloem"
QUARTUS_ROOT="$ACDS_ROOT/quartus"
PATH="$ACDS_ROOT/quartus/bin:$ACDS_ROOT/nios2eds/bin:$MODELSIM_ROOT:.:$PATH"
 
export PATH=$PATH
export QUARTUS_ROOTDIR=$QUARTUS_ROOT
export QUARTUS_HOME=$QUARTUS_ROOT
export LM_LICENSE_FILE=/usr/local/licenseserver/quartus.lic
export ALTERAD_LICENSE=/usr/local/licenseserver/quartus.lic
 
make hw -f Makefile.fpga

With this updated .sh file, you can now run the compile in batch mode, using the command from the oneAPI Getting Started documentation:

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

I will request that Intel addresses this so that the flow is fluid when following the getting started steps.

    Hi, thank you very much for your reply. I have been able to compile my code. However, I still am not able to run it. I have followed your steps to compile but, if I try to run in a "fpga_runtime" node or just "fpga" with the script provided by https://devcloud.intel.com/oneapi/get-started/base-toolkit/#fpga-vector-add-sample-walkthrough I get the error that no device is found:

    u36780@login-2:~/BaseKit-code-samples/DPC++Compiler/vector-add$ qsub -l nodes=1:fpga:ppn=2 -d . run_fpga_hw.sh
    u36780@login-2:~/BaseKit-code-samples/DPC++Compiler/vector-add$ cat run_fpga_hw.sh.o533282

    I have tried both scrips: the run_fpga_hw by default in the documentation and adding paths you provide for compilation with same wrong results:

    u36780@login-2:~/BaseKit-code-samples/DPC++Compiler/vector-add$ cat run_fpga_hw.sh
#!/bin/bash
source /opt/intel/inteloneapi/setvars.sh

MODELSIM_ROOT="$ACDS_ROOT/modelsim_ae/linuxaloem"
QUARTUS_ROOT="$ACDS_ROOT/quartus"
PATH="$ACDS_ROOT/quartus/bin:$ACDS_ROOT/nios2eds/bin:$MODELSIM_ROOT:.:$PATH"
 
export PATH=$PATH
export QUARTUS_ROOTDIR=$QUARTUS_ROOT
export QUARTUS_HOME=$QUARTUS_ROOT
export LM_LICENSE_FILE=/usr/local/licenseserver/quartus.lic
export ALTERAD_LICENSE=/usr/local/licenseserver/quartus.lic
 
make run_hw -f Makefile.fpga

    Am I doing something wrong?

    Thanks a lot

      You certainly aren’t doing anything wrong. Once my compilation completed I also realized that the execution on the FPGA HW is not executing. As far as I can tell, the node setup seems to have changed such that the setup of the driver and/or the OpenCL BSP is not in order.

      I’ve reached out to some folks that are closer to the devcloud node maintenance than I am. Hopefully it can be resolved soon. In the meantime, thanks for your continued patience.
