Issues while running benchmarks for Arm RAN Acceleration Library version 23.04

PankajK

Hi,

I have installed ARM RAL version,23.04 on my Linux machine and successfully built static libraries for Release  mode with Arm GNU Toolchain 12.2.Rel1 (arm-gnu-toolchain-12.2.rel1-x86_64-aarch64-none-linux-gnu.tar.xz) for targets NEON and SVE.I enabled build options ,-DBUILD_TESTING=On` and `-DBUILD_EXAMPLES=On. Python version installed on my machine is 3.8.10.and Linux, Perf tool version is perf version 5.15.87,required for running benchmarks.

After build,I installed ARMRAL libraries for 2 targets in 2 different installation folders.

Afterwords,I tried running benchmarks with command, make bench for 2 targets separately one by one but for each one I am getting errors like following for all benchmarks.....

If I direct o/p to file,JSON objects printed are like below  indicating that benchmarks not ran at all.:--

{"name": "demodulation_qam256_8", "error": true, "ts": 304990550, "dur": 192588}
{"name": "demodulation_qam256_31", "error": true, "ts": 305183343, "dur": 192250}
{"name": "demodulation_qam256_32", "error": true, "ts": 305375812, "dur": 194988}

Since I am evaluating ARMRAL for my work and new to ARMRAL, could you kindly look into the error and help me to identify root cause(eg whether I m missing something/making some error) and fix the error soon?

It would help a lot.

Regards,

Pankaj K

    Dear Pankaj,

    Thank you for getting in touch. Please can you try running the demodulation benchmark directly and letting me know the output? You can do this with the command:

      /home/sitteam/PankajK/arm_lib_2304_build_NEON_static_rel/bench_demodulation 1 276 300000

    If the benchmark runs successfully it will produce the output:

      **** perf_test_demodulation 16QAM, number of iterations = 3000000 *****

    If the benchmark runs successfully, please can you also run it using perf and report the output. The command to do this is:

      perf stat -x " " -e cycles:u /home/sitteam/PankajK/arm_lib_2304_build_NEON_static_rel/bench_demodulation 1 276 300000

    Regards,

    Nick
