Matlab 2014a Licence File 953
Dwaine Hawke
I have just installed Matlab R2011a on Ubuntu 12.04 using a standalone licence. The installation appears to have worked properly, and I have run the following to get rid of an error that everyone (including myself) seemed to be having:
This got rid of the error, but I still have a problem launching Matlab. Each time I launch it (by typing "matlab" in terminal), the Mathworks software activation window pops up. I provide the path to the licence file, it appears to activate successfully (no errors), but then Matlab doesn't launch. If I try to run it again, the same thing happens.
I think the licence should be updated. I fixed the problem by requesting a new licence from Mathworks and activating MATLAB with that licence file. They provided the same installation key for my computer's host id, but the 'licence.lic' file is updated. I think reinstallation is not necessary, activation with an updated licence just solves the problem.
Try running /usr/local/MATLAB/R2011a/bin/matlab (change the path according to the location on your system) in the terminal to see if that runs MATLAB. If not, perhaps you can still get some error messages from there that might be useful for your question.
After toying around with the activation client I finally have a good answer as to why MATLAB will not activate. Here are the steps to getting everything working!! This is also assuming that you have MATLAB installed and cannot get it to launch.
Do everything you did before except this time at the end of the activation when it asks you to type in the name of your computers user, you need to type root, instead of your username or instead of anything you want to put.
Old thread I know, but I just had this same problem. The problem for me at least, was that it is recommended installing matlab with root priviledges and as such when it came to activation the default user to be granted a licens became root. In this way I could only start matlab when logged in as root. Problem is easily fixed by running the activation again outside of root.
Once you have deleted all files within these folders, try launching MATLAB again. Launch it as your regular username, not as sudo or root. You will be prompted to activate once more. Complete the process one last time. Take note on the screen in the activation where it asks you for your Linux username. This should be detected automatically, and you should not change it.
We are a hosting provider for MATLAB. This means that we have MATLAB installed on our clusters and can allow you to access an external license to run computations on our infrastructure. Arrangements have already been made with several Canadian institutions to make this automatic. To see if you already have access to a license, carry out the following test:
If you get the message This version is newer than the version of the license.dat file and/or network license manager on the server machine, try an older version of MATLAB in the module load line.
Otherwise, either your institution does not have a MATLAB license, does not allow its use in this way, or no arrangements have yet been made. Find out who administers the MATLAB license at your institution (faculty, department) and contact them or your Mathworks account manager to know if you are allowed to use the license in this way.
Put this file in the $HOME/.licenses/ directory where the IP address and port number correspond to the values for your campus license server. Next you will need to ensure that the license server on your campus is reachable by our compute nodes. This will require our technical team to get in touch with the technical people managing your license software. Please write to technical support so that we can arrange this for you.
Because the /home directory is accessible in read-only mode on some compute nodes, you should create a .matlab symbolic link that makes sure that the MATLAB profile and job data will be written to the /scratch space instead.
Important: Any significant MATLAB calculation (takes more than about 5 minutes or a gigabyte of memory) must be submitted to the scheduler. For instructions on using the scheduler, please see the Running jobs page.
Do not use the -singleCompThread option if you request more than one core with --cpus-per-task.You should also ensure that the size of your MATLAB parpool matches the number of cores you are requesting.
Each time you run MATLAB, it will create a file like java.log.12345 unless you supply the -nojvm option.However, using -nojvm may interfere with certain plotting functions. For further information on command line options -nodisplay, -singleCompThread, -nojvm, and -r,see MATLAB (Linux) on the MathWorks website.
There is a known issue when two (or more) parallel MATLAB jobs are initializing their parpool simultaneously: multiple new MATLAB instances are trying to read and write to the same .dat file in the $HOME/.matlab/local_cluster_jobs/R* folder, which corrupts the local parallel profile used by other MATLAB jobs. To fix the corrupted profile, delete the local_cluster_jobs folder when no job is running.
You can also compile your code using MATLAB Compiler, which is included among the modules we host. See documentation for the compiler on the MathWorks website. At the moment, mcc is provided for versions 2014a, 2018a and later.
This will produce a binary named cosplot, as well as a wrapper script. To run the binary on our servers, you will only need the binary. The wrapper script named run_cosplot.sh will not work as is on our servers because MATLAB assumes that some libraries can be found in specific locations. Instead, we provide a different wrapper script called run_mcr_binary.sh which sets the correct paths.
MATLAB Parallel Server is only worthwhile if you need more workers in your parallel MATLAB job than available CPU cores on a single compute node. While a regular MATLAB installation (see above sections) allows you to run parallel jobs within one node (up to 64 workers per job, depending on which node and cluster), the MATLAB Parallel Server is the licensed MathWorks solution for running a parallel job on more than one node.
This solution usually works by submitting MATLAB parallel jobs from a local MATLAB interface on your computer. Since May 2023, some mandatory security improvements have been implemented on all clusters. Because MATLAB uses an SSH mode that is no longer permitted, job submission from a local computer is no longer possible until MATLAB uses a new connection method. There is currently no workaround.
Note: When the ccSBATCH.m is in your current working directory, you may try the Cluster Profile Manager validation tool, but only the first two tests will work. Other tests are not yet supported.
The first version has been developed in Matlab and made available as compiled package which does not require a Matlab licence. Changes in the graphics engine of Matlab and the exploding download size of the Matlab runtime environment made it more and more difficult to maintain the package.
Therefore, SAXSutilities was rewritten in 2019/2020 using Python3. The program is available as a complete package (using pyinstaller) containing all required libraries. Versions for Windows and Linux are available (tested under Debian8).
The ASAXS and fitting routines implemented in the original SAXSutilities package have not been ported to Python3. Therefore, a SAXSutilities package in Matlab with support for handling 1D ASCII files is maintained. It is based on Matlab 2014a 32bit (Windows) or Matlab 2013b (LINUX) for compatibility reasons.
If you are interested in how to use MATLAB, come tofree software workshopsoffered by CIRC. They are held during Fall and Spring semesterson Wednesdays during Free Hour (12noon-01pm) in room ENGR 122,an instructional computer lab in the Engineering Building at UMBC.The workshops on MATLAB form a sequence that covers topicsfrom a basic introduction to efficient simulations.
For a more thorough introduction with guided homework projects, considerthe official 2-credit classMATH 426 Introduction to Math Software Packages: MATLABthat the Department of Mathematics and Statistics offersin Summer and Winter semesters.
MATLAB's name originates from Matrix Laboratory, since itwas originally written as a teaching tool to support an introductorylinear algebra class (like MATH 221 at UMBC).Since that first version, it has been extended and upgraded tobe one of the most versatile and popular packages for numerical computationsand graphing. It is widely used in industrial companies, government agencies,and educational institutions for rapid prototyping and teaching. Its mainpopularity roots in its intuitive interactive interface combined with reliablenumerical algorithms and professional graphics capabilities.
UMBC maintains a campus licences for MATLAB and many of its toolboxes.The most efficient way to run MATLAB is to use a lab PC and run it locally.You may also run it remotely on several of the gl systems.
Under Windows 7 or 8, click on theWindows Start Orb to open the Start Menu, type "matlab" tosearch for the program, then click on the version you want to run. MATLAB mightremember whether you had other windows open at the end of your previoussession, so the Help browser (which might even open with the page you lastvisited) and other windows may open again.
At present (8/2013), in the UMBC computer labs, MATLAB starts up in a foldersimilar to \\profile.ad.umbc.edu\Userfiles$\username\My Documents\MATLAB. Thisdirectory is visible in the "Current Folder Toolbar" above the other desktopwindows and below the "Toolstrip".
As an example of how to create a directory structure for your currentproject, here are instructions that a student in Math 426 can use to toorganize her files for that course. First, create a folder for this class byentering "mkdir Math426" on the MATLAB command line(the window with the >> prompt),and then change into it by entering "cd Math426".Next, create a directory for each homework byentering "mkdir Homework1" and change to it by entering"cd Homework1".Check what the Current Folder Toolbar says or enter"pwd" (print working directory) at the MATLAB command line.
