Example usage of Matlab in interactive modeĪt this point you should have downloaded the example scripts and started Matlab either with the graphical or the text-mode While the text mode interface is spartan, you still benefit from tab-completion (type the first few letters ofĪ command then press TAB twice to see possible completions) and can run the integrated help with help command_name However be generated and exported to file, which you will need to transfer to your own machine for visualisation. In this command line you are now able to run Matlab commands, load and edit scripts, but cannot display plots - they can To get started, type one of these: helpwin, helpdesk, or demo.įor product information, visit > version() Opening log file: /home/users/vplugaru/java.log.46818 # Launch MATLAB with the graphical display mode disabled (critical parameters): Quick executions: # Connect to Iris, start an interactive job with 14 cores for 1 hour:

Using the full graphical environment through the network and is useful for commands/scripts testing and Running the text-mode MATLAB interface in an interactive session, is much faster than Use all 112 cores within a node from the bigmem partition, with ~27GB RAM/core salloc -p bigmem -N 1 -n 1 -c 112 bash -c 'ssh -X $(scontrol show hostnames | head -n 1)' Use all 28 cores within a node from the interactive partition, with 4GB RAM/core salloc -p interactive -N 1 -n 1 -c 28 bash -c 'ssh -X $(scontrol show hostnames | head -n 1)' Note: to request a full Iris node for a large interactive experiment you can: An alternative to the graphical interface is the command-line (text-mode) interface, which isĮnabled through specific parameters, described in the following section. # Check that its profile has been loaded and thus we can start to use it:Īfter a delay, the full Matlab interface will be displayed on your machine and you will be able to run commands, load and edit # Check the Matlab versions installed on the clusters: (access-iris)$> salloc -p interactive bash -c 'ssh -X $(scontrol show hostnames | head -n 1)'

# Request an interactive job (the default parameters get you 1 core for 2 hours) with an X11 tunnel: # Connect to Iris with X11 forwarding enabled (Linux/OS X): Then configure Putty (Connection -> SSH -> X11 -> Enable X11 forwarding) before logging in to Iris.
#Matlab tutorial windows
On Windows you will either need to use MobaXTerm or if you use Putty, run VcXsrv first The first command below returns an 'X11 forwarding request failed on channel 0' error On OS X (depending on version) you may not have the X Window System installed, On Linux simply follow the commands below Running the full MATLAB environment on the Iris cluster will require you to enable X11 forwarding in order for the graphical environment to be shown on your Matlab execution in interactive mode Launching the full graphical environment (access-iris)$> ln -s tutorials/maths/matlab/basics ~/matlab-tutorial Or simply clone the full tutorials repository and make a link to this part of the MATLAB tutorial: (access-iris)$> git clone (access-iris)$> wget -no-check-certificate (access-iris)$> cd ~/matlab-tutorial/code

PrerequisitesĪs part of this tutorial two Matlab example scripts have been developed and you will need to download them,Īlong with their dependencies, before following the instructions in the next sections: (access-iris)$> mkdir -p ~/matlab-tutorial/code

how to take advantage of some of the paralelization capabilities of MATLAB to speed up your tasksįor the tutorial we will use the UL HPC Iris cluster that includes nodes with GPU accelerators.
