Error compiling hello_world.cl with aoc

[gbarc2]

I recently installed the Intel OpenCL SDK toolchain for FPGA on a Linux system by following the guide provided here https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/opencl-sdk/aocl_getting_started.pdf.

Since our board is an Intel PAC with Arria 10 GX, I also installed the Custom Platform for the board.

Running

aoc -version

Intel(R) FPGA SDK for OpenCL(TM), 64-Bit Offline Compiler

Version 17.1.1 Build 273

Copyright (C) 2017 Intel Corporation

quartus_map --version

Quartus Prime Analysis & Synthesis

Version 17.1.1 Build 273 12/19/2017 Patches 1.02dcp,1.36,1.38 SJ Pro Edition

Copyright (C) 2017 Intel Corporation. All rights reserved.

therefore aoc and Quartus are installed. I also ran "aocl diagnose" and it correctly passed the diagnostic for the board.

Then compiling the hello_world.cl kernel in emulation mode

aoc -v -march=emulator -board=pac_a10 hello_world.cl

worked without any problem (also at runtime the binary worked).

However, running

aoc -v -board=pac_a10  hello_world.cl

c: Environment checks are completed successfully.

aoc: Cached files in /var/tmp/aocl/ may be used to reduce compilation time

You are now compiling the full flow!!

aoc: Selected target board pac_a10

aoc: Running OpenCL parser....

aoc: OpenCL parser completed successfully.

aoc: Optimizing and doing static analysis of code...

aoc: Linking with IP library ...

Checking if memory usage is larger than 100%

aoc: First stage compilation completed successfully.

Compiling for FPGA. This process may take a long time, please be patient.

Error: Compiler Error, not able to generate hardware

Therefore, I looked at hello_world.log (see attached) and there is no indication of why the compilation failed.

Then, I looked at quartus_sh_compile.log and the only line reported is

ERROR: packager tool failed to run. Check installation. Aborting compilation!

Could you please help us understand where the issue may be?

Many thanks.

Hi gbarc2,

Can you try to run in the latest version of the software?

Thanks

[gbarc3]

Hi KYeoh,

we installed the software stack for the Intel PAC after downloading it from here https://www.intel.com/content/www/us/en/programmable/solutions/acceleration-hub/downloads.html

If there is any way to download a more recent version of the software, could you provide us a download link and/or instructions?

Many thanks

[KhaiChein_Y_Intel]

Hi gbarc3,

The error suggests you to check the installation. Could you update the version to v18.1?

ERROR: packager tool failed to run. Check installation. Aborting compilation!

Thanks.

Could you please provide a link to instructions for installing the Arria 10 PAC with v18.1?

[KhaiChein_Y_Intel]

Hi JMilt1,

May I know what is the available RAM ? Could you share the bin/hello_world/quartus_sh_compile.log file?

Thanks

[JMilt1]

I've attached my device/hello_world/quartus_sh_compile.log file. Are you asking what is the amount, or the kind, of available RAM on the board? How would I query this? (It's an Arria 10 GX PAC, if that helps.)

[KhaiChein_Y_Intel]

Hi JMilt1, I am referring to processor RAM. Thanks

[JMilt1]

By 'processor', I assume you mean the FPGA. We did not change any of the memory settings from their defaults. How would I query to find out the available memory?

[KhaiChein_Y_Intel]

Hi JMilt1,

The theorized root cause there is that the Intel Quartus Prime software is using all the available processors, and the machine doesn't have enough memory to support use of all those processors.

Could you try to limit the number of processors being used by the Intel Quartus Prime software, for example to 2?

Thanks.

[JMilt1]

I tried limiting `aoc` to a single core using taskset. It worked in the sense that max CPU usage was 100%, rather than 600%, however, there seemed to be no difference in the memory usage - either way it used around 8.3GB before crashing with the same error "Error: Compiler Error, not able to generate hardware".

[HRZ]

"Processor" refers to the host processor in YY's reply, not the FPGA. You need 32 to 64 GB of host memory for one instance of Arria 10 placement and routing. How much memory is installed on the machine that you are using for placement and routing?

Also the "quartus_sh_compile" log you posted earlier does NOT show any errors and the process has finished successfully. Can you post the log for a compilation that failed?

[JMilt1]

We have 96GB of memory on the host processor.

As gbarc2 said, for the failing compilations, the only line in the quartus_sh_compile.log for the failing compilation is:

ERROR: packager tool failed to run. Check installation. Aborting compilation!

Hi gbarc2,

i have the same error compiling hello_world.cl with aoc.

Is there any solution?

Thanks

Hi, Do you have all the required Linux packages installed? https://www.intel.com/content/www/us/en/programmable/documentation/iyu1522005567196.html#isp1528500494491 May I know what OS you are using? Thanks.

Hi,

i use Ubuntu 16.04.6 LTS (Xenial Xerus),

The error in quartuserr.tmp:

How the script packager.pyz (exm_opencl_hello_world/hello_world/bin/hello_world/build/tools/packager.pyz) is generated?

Thanks

[SMelz]

sudo apt-get install python-jsonschema

and it works.

[KhaiChein_Y_Intel]

Hi gbarc2,

What OS you are using? Can you try the suggestion from Simon?

Thanks.

[KhaiChein_Y_Intel]

Hi gbarc2, May I know if you have any updates? Thanks

If you use Ubuntu16.04 for your PC, this URL would solve your problem.
