New ContributorDevCloud: Cannot compile Stratix 10 kernel (Tcl error)
This issue was not solved.
However, there is another post discussing the same issue, which has been acknowledged and reproduced by Intel staff. A solutions is supposedly being worked on, and updates will be posted in that post.
Thus, discussion on this issue has been moved to that post:
https://community.intel.com/t5/Intel-DevCloud/FPGA-Builds-Broken-on-DevCloud/m-p/1439447
Frequent Contributorplease update status of your issue. based on that i will get an idea.
Mdcc_UVaHello. Sorry for the delay. Some of the compilation times are quite high, and the time I can dedicate to this daily is limited.
First off, as suggested, I followed this guide: https://devcloud.intel.com/oneapi/documentation/job-submission/
I created the following job submission script, compile.sh:
#/bin/bash source /glob/development-tools/versions/fpgasupportstack/d5005/2.0.1/inteldevstack/init_env.sh source /glob/development-tools/versions/fpgasupportstack/d5005/2.0.1/inteldevstack/hld/init_opencl.sh export FPGA_BBB_CCI_src=/usr/local/intel-fpga-bbb export PATH=/glob/intel-python/python2/bin:${PATH} time aoc -v -report -march=emulator mykernel.cl -o mykernel_emu.aocx time aoc -v -report -board-package=/opt/intel/oneapi/intel_s10sx_pac mykernel.cl -o mykernel.aocxI submit it to a Stratix 10 compilation node using the following command:
qsub -l nodes=1:fpga_compile:ppn=2 -d . compile.shThe following is the output (stdout) for the job, compile.sh.o2114020. The output isn't trimmed in any way, so you have access to the full information. Note the error messages at the end.

I followed the process described in the official documents/guides for job submission and OpenCL FPGA kernel compilation, which never refer to Tcl scripts. I never opened or modified in any way a Tcl script, and I do not even know where they are located in the system.
The following is the error output (stderr) for the job, compile.sh.e2114020. The output isn't trimmed in any way, so you have access to the full information.
Error: OpenCL kernel compilation FAILED real 0m10.103s user 0m1.544s sys 0m1.244s Error: Compiler Error, not able to generate hardware real 70m58.990s user 75m20.593s sys 0m56.989sThe first error message corresponds to the compilation using -march=emuator (i.e., compiling for emulation fails). The second error, which happens past the hour of compilation, corresponds to the compilation targeting a Stratix 10 PAC (i.e., compiling for a real FPGA fails).
After the job finished, the following files are generated: mykernel.aoco, mykernel.aocr, but not mykernel.aocx.
That's what happens when I follow the Job Submission guide. I do not know what the problems are exactly nor how to fix them.

Just out of curiosity, I also tried not following the official guide, and trying to compile the kernel as I used to be able to compile it. I read in some other forum post that setting a specific value for the QUARTUS_ROOTDIR_OVERRIDE environmental variable and using a specific aoc binary for compilation helped fixing some issues with the compilation process.
Thus, I created a new job submission script for the compilation of the OpenCL kernel, x.sh:
#!/bin/bash QUARTUS_ROOTDIR_OVERRIDE=/opt/intel/intelFPGA_pro/19.2/quartus /glob/development-tools/versions/oneapi/2022.2/oneapi/compiler/2022.1.0/linux/lib/oclfpga/bin/aoc -board-package=/opt/intel/oneapi/intel_s10sx_pac mykernel.cl -o mykernel.aocxThe job is submitted using the same command:
qsub -l nodes=1:fpga_compile:ppn=2 -d . x.shExecuting this job produces no error output (stderr), and produces a normal, error-less output (stdout):

I join a FPGA execution node using the following command:
qsub -I -l nodes=1:fpga_runtime:stratix10:ppn=2 -d .Which assigns me the node s001-n142. Then I execute the OpenCL program that uses this kernel.
This execution works completely fine. Other times I tested it, it seemed to not work. If I find another of those cases again, I will report it as soon as possible.
However, I am worried that the only way for my program to work/be properly compiled is to not to follow the Job Submission guide for OpenCL FPGA kernels. I do not know if that is intended, or something is wrong regarding OpenCL FPGA kernel compilation.
