kandi X-RAY | mersennetwister Summary

mersennetwister is a JavaScript library typically used in Server, Runtime Evironment, Nodejs applications. mersennetwister has no bugs, it has no vulnerabilities and it has low support. However mersennetwister has a Non-SPDX License. You can install using 'npm i mersennetwister' or download it from GitHub, npm.

The Mersenne Twister is a pseudo-random number generator invented by Makoto Matsumoto in 1997. Details can be found on the Wikipedia page and on Matsumoto's website. This implementation is based on Sean McCullough's port of the original C code written by Makato Matsumoto and Takuji Nishimura. Improvements over Sean's version are. Please note that the mersenne twister is not cryptographically secure.

            clang ignores -std=c++11 flag for include files
            Asked 2021-Oct-20 at 03:16

            I have some code that I use a (old) Mersenne Twister header file with to get a good pseudo-random number generator.

            The problem is that that code uses the register keyword which (as far as I understand) was deprecated in c++11 and throws an error with c++17. I believe I am using the latter in the version of clang I'm using on Mac OSX (10.14.6; Mojave).

            How do I dissable Spring's Autowiring of specific fields in a class?
            Asked 2021-Oct-05 at 15:19

            Below is a class which uses the @Configuration annotation to create a Bean. I am slowly introducing Spring into a legacy Java application. I don't want to Spring-ify everything all at once - that would be crazy. I thought I'd start with one of the commonly used utility classes and I don't want Spring to create Beans for the three fields below (Enumerator, RandomDataGenerator, AliasMethodFactory). How do I turn off Autowiring for those fields? Spring is currently complaining that it can't find Beans for those (it's obviously trying to auto-wire them).

            How can I use randjump instead of generating a certain number of random numbers?
            Asked 2021-Mar-04 at 13:15

            I am trying to "skip forward" a few realizations by using the function Future.randjump(), but it doesn't seem to behave as I expect it to. The following code gives me the desired result, where jumping forward 1 steps gives the same result as if I had called rand(rng) twice, i.e. the two println display the same number:

            Random number seeds for Julia cluster computing
            Asked 2021-Jan-13 at 22:54

            I have a Julia code, and I want to submit this code to a remote computing cluster via running a large number of jobs in parallel (i.e., around 10,000 jobs in parallel). The way this code works is that, the main function (call it "main.jl") calls another function (call it "generator.jl") which utilizes random numbers such as rand(Float64) and so on. I submit main.jl via a bash file, and I run N jobs in parallel by including

            There are two issues here:

            1. Getting the job number
            2. Using the job number in random number generation.

            Each of those issues has two solutions - one more and other less elegant but also OK.

            Ad.1. For managing job numbers consider using PBS together with ClusterManagers.jl. There is a command there addprocs_pbs(np::Integer; qsub_flags="") that will make it possible to manage the run numbers and orchestrate the cluster from within Julia. In many scenarios you will find this approach more comfortable. Here you can use for seeding the random number generator (more on that later) myid() that returns the worker number. Anyway most likely you will in this scenario run your computations using the @distributed loop and you can use that value for seeding RNG. If you are rather orchestrating array jobs externally via bash scripts then perhaps the best thing is to pass the job number via a parameter to the Julia process and read it from ARGS variable or have a setup bash script that exports an environmental parameter that can be read from ENV variable.

            Ad.2. There are two approaches here. Firstly you can simply create a new MersseneTwister at each worker and then use it in the streams. For an example (here I assume that you use some variable jobid):

            Julia 1.5.2 Initiating random number selection in parallel
            Asked 2020-Nov-24 at 01:59

            I am currently attempting to run my code in parallel. Part of my code (genetic algorithm) relies on the selection of random numbers. Therefore, I need to make sure that each thread used, have their own random number generator. I must also be able to replicate the results. Therefore, I have "borrowed" a function, which has the ability to set a random seed or create specific seeds for each thread.

            https://discourse.julialang.org/t/how-do-i-deal-with-random-number-generation-when-multithreading/5636/2

            In order to test if this was working correctly, I wanted to set the seeds equal for each thread and test to see if the same random numbers were generated. However, this was not the case!

            I believe that I am missing something fundamental about the generation of the numbers. When creating the random number generators, I have used the same UInt32. I believe that they should therefore draw the same numbers, however the randjump may interfere with this. Perhaps the random number generators do not "jump" forward to the same point/state to ensure that each is far enough from each other in the cycle. Perhaps they share a state when doing it this way? Is there a way to control if the implementation is accurate? Perhaps there is a bigger error at play here?

            You basically do not need to use randjump because the MersenneTwister streams are not correlated.

            Hence, the standard way to initiate the random streams for threads is the following:

            Simply run npm install mersennetwister (or npm install --save mersennetwister of you want to directly add it to your package.json file). Import as usual: var MersenneTwister = require('mersennetwister');. Use the Jam command line tool: jam install mersennetwister and import as usual require(['mersennetwister'], function (MersenneTwister) { ... Via the Bower tool: bower install mersennetwister. Tools like Jam will usually configure requirejs so that it can be accessed via its package name (i.e., mersennetwister). If you use requirejs without such a customized configuration you need to import it via its camelcased filename: requirejs(['MersenneTwister'], function (MersenneTwister) { ... Download and include the src/MersenneTwister.js file: <script src="path/to/MersenneTwister.js"></script>. It is now available as the global variable MersenneTwister.
