I've implemented single work-item ( using SYCL single_task ) Acorn-128 encrypt/ decrypt FPGA kernels, which can be used for computing encrypted text using Acorn-128 authenticated encryption algorithm/ decrypted text using Acorn-128 verified decryption algorithm on N -many independent & non-overlapping plain/ cipher text byteslices & respective associated data byteslices.
Note, associated data byteslices are never encrypted, only plain text byteslices are.
N -many invocations of Acorn-128 encrypt/ decrypt routine are not spawn in well familiar multi work-item data-parallel fashion ( read SYCL parallel_for ), instead single work-item kernel's iterative execution style is preferred, while leveraging deep pipelining in synthesized FPGA h/w image.
In following benchmark setting associated data length is kept same ( = 32 -bytes ), while plain/ cipher text length is chosen to be power of 2 ( -bytes ), from range [64..4096] ( read both ends are inclusive ). Number of times iteration is executed inside body of single work-item kernel ( i.e. N ) ∈ {2^16, 2^17, 2^18}.
Intel Devcloud is used for submission of FPGA h/w synthesis & h/w image execution jobs.
Learn more about Intel Devcloud here.
First prepare job submission script like
touch build_fpga_bench_hw.shPut following content inside job submission script
#!/bin/bash
# file name: build_fpga_bench_hw.sh
# env setup
export PATH=/glob/intel-python/python2/bin/:${PATH}
source /opt/intel/inteloneapi/setvars.sh > /dev/null 2>&1
# hardware compilation
time make fpga_hw_benchThen enqueue job to generate h/w image on fpga_compile tagged VM on Intel Devcloud.
qsub -l nodes=1:fpga_compile:ppn=2 -l walltime=24:00:00 -d . build_fpga_bench_hw.shSuccessful submission should generate job id ( looks like 1882236 ), take a note of it.
Once FPGA h/w synthesis is finished, another dependent job will kick in to execute synthesized h/w image & collect benchmark metrics.
First prepare job submission script
touch run_fpga_bench_hw.shPut following content inside that script
#!/bin/bash
# file name: run_fpga_bench_hw.sh
# env setup
export PATH=/glob/intel-python/python2/bin/:${PATH}
source /opt/intel/inteloneapi/setvars.sh > /dev/null 2>&1
# hardware image execution
pushd bench; ./fpga_hw_bench.out; popdNow create job dependency graph, using already obtained compilation job id, when submitting execution job.
qsub -l nodes=1:fpga_runtime:arria10:ppn=2 -d . run_fpga_bench_hw.sh -W depend=afterok:1882236Execution job submission should also generate one job id, though we don't need it at this moment.
