Running oneAPI C++SYCL_FPGA GettingStarted Example on devcloud

Hello,

I am quite new to everything and I tried to run some examples in

oneAPI-samples/DirectProgramming/C++SYCL_FPGA/Tutorials/GettingStarted
/fpga_compile/

(https://github.com/oneapi-src/oneAPI-samples/tree/master/DirectProgramming/C%2B%2BSYCL_FPGA/Tutorials/GettingStarted/fpga_compile)

I've heard using modelsim or questa on devcloud is not possible, so I am trying to compile and run fpga_emu, report and fpga. (without the simulation using modelsim)

Actually, I already run these examples recently.

I remember it was last Monday.

But, I tried it again today with same steps, but it was very different from the last time.

The steps I took last time:

1. log in to devcloud using MobaXterm using

$ ssh devcloud

2. access node using

$ devcloud_login

I chose number 2 which included ARRIA10 oneAPI

3. move to the project directory and make build directory

4. in build directory, do

$ cmake .. -DFPGA_DEVICE=ARRIA10

5. compile and run fpga_emu

$ make fpga_emu

$ ./vector_add.fpga_emu

6. compile and look at report

$ make report

** I could not find any way to open the report file (vector_add_report.prj/reports/reports.html) so I had to zip the report folder and transfer it to my local laptop and open it there. Please let me know if there is any better way to see the reports.html file in ssh!**

7. compile and run fpga

$ make fpga

$./vector_add.fpga

I remember that these were the steps I took and all compiled and showed the results correctly with no errors.

Last time, I also compiled fpga_emu and report for ReferenceDesigns/matmul example with no errors.

But today, I had problems starting from step 5 above (fpga_emu compile).

So, I accessed it in fpga compile node by (instead of the step 2 above: devcloud_login)

$ qsub -I -l nodes=1:fpga_compile:ppn=2 -d .

This allowed me to compile fpga_emu, report and fpga.

But running the fpga compile result file did not work

To overcome this problem, I tried:

i) log in to runtime node by

$ qsub -I -l nodes=1:fpga_runtime:arria10:ppn=2 -d .

ii) do

$ cmake .. -DFPGA_DEVICE=/opt/intel/oneapi/intel_a10gx_pac:pac_a10

instead of step 4 (cmake .. ) above

iii) initialize fpga. Did not reach this step because error occurred when doing

$ aocl diagnose all

error msg when I tried the command after connecting to runtime node as (i):

To summerize, I was curious

- why it worked last time so simply but it does not work now

- how to initialize FPGA in devcloud if I should do it

- any other things I missed to run the examples?

Thanks in advance,
