            JMH using java 17, no dead code elimination
            Asked 2022-Feb-09 at 17:17

            I run sample JHM benchmark which suppose to show dead code elimination. Code is rewritten for conciseness from jhm github sample.

            Those samples depend on JDK internals.

            Looks like since JDK 9 and JDK-8152907, Math.log is no longer intrinsified into C2 intermediate representation. Instead, a direct call to a quick LIBM-backed stub is made. This is usually faster for the code that actually uses the result. Notice how measureCorrect is faster in JDK 17 output in your case.

            But for JMH samples, it limits the the compiler optimizations around the Math.log, and dead code / folding samples do not work properly. The fix it to make samples that do not rely on JDK internals without a good reason, and instead use a custom written payload.

            This is being done in JMH here:

            Is the timing of MATLAB reliable? If yes, can we reproduce the performance with julia, fortran, etc.?
            Asked 2022-Jan-05 at 08:26

            Originally this is a problem coming up in mathematica.SE, but since multiple programming languages have involved in the discussion, I think it's better to rephrase it a bit and post it here.

            Answered 2021-Dec-30 at 12:23

            tic/toc should be fine, but it looks like the timing is being skewed by memory pre-allocation.

            I can reproduce similar timings to your MATLAB example, however

            • On first run (clear workspace)

              • Loop approach takes 2.08 sec
              • Vectorised approach takes 1.04 sec
              • Vectorisation saves 50% execution time
            • On second run (workspace not cleared)

              • Loop approach takes 2.55 sec
              • Vectorised approach takes 0.065 sec
              • Vectorisation "saves" 97.5% execution time

            My guess would be that since the loop approach explicitly creates a new matrix via zeros, the memory is reallocated from scratch on every run and you don't see the speed improvement on subsequent runs.

            However, when HH remains in memory and the HH=___ line outputs a matrix of the same size, I suspect MATLAB is doing some clever memory allocation to speed up the operation.

            We can prove this theory with the following test:

            I cannot reproduce your issue using:

            1. openjdk:8-jre-alpine docker image
            2. JMeter 5.4.1
            3. Test plan Test.jmx from extras folder of JMeter


            If you cannot reproduce the above behaviour I think you made some changes either to Results File Configuration or to Reporting Configuration or both so you need to inspect all the JMeter Properties which differ from the defaults and restore their values to the original ones.

            If you need further support you need to share at least first 2 lines of your outFilePath.jtl results file. Better if possible the full file and all the .properties files from JMeter's "bin" folder.

            You end up with the error with precision because some of your penalization is too strong for this model, if you check the results, you get 0 for f1 score when C = 0.001 and C = 0.01

            I've installed Windows 10 21H2 on both my desktop (AMD 5950X system with RTX3080) and my laptop (Dell XPS 9560 with i7-7700HQ and GTX1050) following the instructions on

            1. Install CUDA-capable driver in Windows
            2. Update WSL2 kernel in PowerShell: wsl --update
            3. Install CUDA toolkit in Ubuntu 20.04 in WSL2 (Note that you don't install a CUDA driver in WSL2, the instructions explicitly tell that the CUDA driver should not be installed.):


            Answered 2021-Nov-18 at 19:20

            Turns out that Windows 10 Update Assistant incorrectly reported it upgraded my OS to 21H2 on my laptop. Checking Windows version by running winver reports that my OS is still 21H1. Of course CUDA in WSL2 will not work in Windows 10 without 21H2.

            After successfully installing 21H2 I can confirm CUDA works with WSL2 even for laptops with Optimus NVIDIA cards.
