Running long simulations on Matlab Online

40 views (last 30 days)
Hi all,
I have Monte-Carlo simulations that take hours to finish (~ 17 hours). I was using a Desktop in my university Lab for this purpose, where I can keep it ON for days. But unfortunately, now I can't access it and I can't run Matlab on my laptop for that long time. By coincidence I discovered Matlab Online, and I'm wondering now is there a way to keep my code running on it even after I log out. Also, can it run 'parfor'.
Best Regards,

Even I have similar kind of computation requirement (approx 72hours). Any ideas by anybody ?

You could run a batch job submitted from your desktop machine to a cluster somewhere. You need access to a MATLAB Distributed Computing Server cluster installation. Perhaps your university already has one; otherwise, you might be able to take advantage of one of the cloud computing offerings that allow you to run batch jobs.

I doubt you would be able to find a service that was willing to give you 17 hours of free computing (if services like that existed, people would use them for bitcoin mining.)
What you just might be able to find is a research computing service together with grants to pay for the service. For example, or

Unfortunately, MATLAB Online will not keep running after you log out, and it also has an interaction time-out of 50 minutes.
I have no information about whether it can run parfor.

Hi @Walter Roberson I am using MATLAB-academic. My model is running fine for small time interval but not for long time simulation (~ 1800000 sec). Can you guide regarding this?

You can add a custom function at the end of your script. For data preprocessing, the function should take the data returned from the datastore as input. It should return the transformed data as output.
function dataout = functionName(datain)
% do something with datain
dataout = ...
TASKCreate a function called scale at the end of the script that performs the following operations:
data.Time = (data.Time - data.Time(1))/1000;
data.X = 1.5*data.X;
Because these commands modify the variable data directly, your function should use data as both the input and output variable.
Note that the third line of the script calls the scale function. Your script won't run until this function has been created.
Also note that local functions must be at the end of a script. This means you will be editing the script sections out of order in this interaction. The section headings show which section of the script to edit in each task.

This is not a solution to the question asked.
