Many users are struggling with optimizing their Julia code for performance, often comparing it unfavorably to other languages like Python and C++. They are seeking advice on best practices, specific optimization techniques, and help from consultants to improve their code's efficiency.
Looking for Some Best Practices for Optimizing Julia Code Performance?
“Hi everyone, I am new to Julia and absolutely loving its speed and simplicity so far. However, as I start working on more complex projects…, I would like to ensure my code is as efficient as possible. I have read about Julia's impressive performance potential, but I am aware that achieving optima...”
Open original →"Very optimised" Julia code 50x slower than Python with compiled functions
“Hi All, I am doing some Monte Carlo computation using Python (compiling some functions to C++ using the Numba package). I thought I would see how Julia compares. As is good programming practice, I scraped some code from the Internet https://shinaoka.github.io/hpc_julia/docs/2dIsing.html Ising 2D ...”
Open original →C++ code much faster than Julia how can I optimize it?
“I’m trying to adapt this https://github.com/dstein64/kmeans1d/blob/master/kmeans1d/_core.cpp C++ code to Julia ( https://github.com/Adegasel/julia_1dkmeans/blob/master/scr/_core_trans.jl here my translation). However C++ original code is much faster than Julia. How can I optimize it?”
Open original →Parameter estimation of an ODE in Julia is slower than in R
“I’ve been trying to estimate parameters (using max likelihood) of an ODE using the DifferentialEquations and Optim packages in Julia aiming to get a faster convergence compared to R. Problem is that I still can do it faster in R. The only advantage so far is that I get a lower value of likelihood...”
Open original →Performance issues with parallel Julia code
“I am working on a scientific code that is experiencing issues with parallelization. The parallel version is slower than the serial one and I am not sure if the right approaches are used for this application. How can I improve the performance of the parallel calculation? Is the right approach bein...”
