FPGA Build fail on Devcloud

Hello,

I'm trying to compile a project on FPGA Hardware on Devcloud.

following these steps:

qsub -I -l nodes=1:fpga_compile:ppn=2 -l walltime=24:00:00

source /opt/intel/inteloneapi/setvars.sh

mkdir build

cd build 

cmake ..

make fpga

I'm targeting intel_s10sx_pac:pac_s10

this is the output of the compilation:

Scanning dependencies of target onesql
[ 33%] Linking CXX static library ../libonesql.a
[ 33%] Built target onesql
Scanning dependencies of target main_fpga.fpga
[ 66%] Building CXX object CMakeFiles/main_fpga.fpga.dir/main_fpga.cpp.o

this is the content of the main_fpga_757e3b_527f59.log file

Killed

The project compile and run on FPGA Emulator and I'm also able to build the report.

Anyone seeing this error or know hot to fix it?

Thank you in advance.

It seems like the process is getting killed, likely due to lack of enough memory. FPGA synthesis requires a very large amount of memory. Do you have the amount of memory recommended below on the machine you are performing the synthesis on?

Hello,

I'm compiling on Devcloud, this is the result of the "free" command:

total used free shared buff/cache available
Mem: 16037092 4326092 852364 3360 10858636 11420228
Swap: 999420 531948 467472

I'm targeting "intel_s10sx_pac:pac_s10"

That machine only has 16 GB of memory, that is not even remotely enough to synthesize a design for Stratix 10. Doesn't DevCloud have specific nodes for synthesis?

Hi giulio2,


Thank you for posting in Intel community forum and hope all is well.

My guess is that the command is submitted in the headnodes and did not specify the desire node.

Hence would suggest to use the devcloud_cloud command to access the specific desire node and try to compile the project again.

Hope that helps.
