A very ressource efficient Matlab class for progress monitoring during a `parfor` loop displaying the remaining time and optional progress of each worker. The only way around this is to use another process that reports the progress. There is no need to create a parpool object manually. Viewed 20k times . The original ParforProgMonv3 solves this by letting the user choose a stepSize manually. I, however, only have R2013a, so unfortunately this doesn't work for me.

Is it possible for a gas fired boiler to consume more energy when heating intermitently versus having heating at all times? Since each simulation takes a lot of time, I usually print progress using something like. the progress of all workers (default: false). This function amends a character to a file on every iteration and then reads the number of characters written to that file which indicates the number of iterations completed. You can write a quick script to monitor the progress of your code. 2. I would prefer to use ZeroMQ / JeroMQ-port and explicitly signal from inside the parfor any actual (relevant) progress.

But you have x-1 workers that don't get delayed at all (calling increment has a neglegible effect even for millions of iterations). Starting in R2013b, you can use PARFEVAL to evaluate your function asynchronously and have the client display progress updates. 1. % do some parallel computation A temporary file is written to by worker threads to record the completion of each parfor iteration and a timer periodically updates the progress bar.
