Loads the correct matlab module and executes the binary. The wrapper script hello_world.sh #!/bin/bash Requirements = OSGVO_OS_STRING = "RHEL 7" & Arch = "X86_64" & HAS_MODULES = True Log = Log/job.$(Process).log # log information about job execution Output = Log/job.$(Process).out⋅ # standard outputĮrror = Log/job.$(Process).err # standard error Transfer_input_files = hello_world # list of file(s) need be transffered to the remote execute point
Let us take a look at hello_world.submit file: Universe = vanilla # One OSG Connect vanilla, the preffered job universe is "vanilla"Įxecutable = hello_world.sh # Job execution file which is transfered to execute point
COMPILER MATLAB 2018B HOW TO
Next, we see how to submit the job on a remote execute point using HTcondor. If you get the above output, the binary execution is successful. The above command sets up the environment to run the matlab/2018b runtime applications. On the terminal prompt, type $ module load matlab/R2018b Load the MATLAB runtime for 2018b version via module command. In addition to the platform requirement, we also need to have the same MATLAB Runtime version. The login node and many of the worker nodes on OSG are based on Linux platform. The file hello_world is a standalone binary of the matlab program hello_world.m which was compiled using MATLAB 2018b on a Linux platform. The compilation and execution environment need to the same. Hello_world.submit # condor job description file Inside the directory, you will see the following files hello_world # compiled executable binary of hello_world.m This will create a directory tutorial-matlab-HelloWorld. Alternatively, you may also use the readily available files by invoking the tutorial command: $ tutorial matlab-HelloWorld # Copies input and script files to the directory tutorial-matlab-HelloWorld. Let us say you have created the standalone binary hello_world. This module can be loaded directly: module load matlab/R2018b To see which releases are available on OSG: $ ssh # login on OSG connect login node Running standalone binary applications on OSG We just need the standalone binary file hello_world. mccExcludedFiles.log is the log file and readme.txt contains the information about the compilation process. The file run_hello_world.sh is MATLAB generated shell script.
The file hello_world is the standalone executable. The compilation would produce the files: `hello_world, run_hello_world.sh, mccExcludedFiles.log` and `readme.txt` The flag -m means C language translation during compilation, and the flag -R indicates runtime options. We turn off all graphical options ( -nodisplay), disable Java ( -nojvm), and instruct MATLAB to run this application as a single-threaded application ( -singleCompThread): mcc -m -R -singleCompThread -R -nodisplay -R -nojvm hello_world.m
COMPILER MATLAB 2018B LICENSE
OSG connect does not have a license to use the MATLAB compiler. Lets start with a simple MATLAB script hello_world.m that prints Hello World! to standard output. In this tutorial, we learn the basics of compiling MATLAB programs on a licensed linux machine and running theĬompiled binaries using a matlab compiled runtime (MCR) in the OSG modules or containers.
COMPILER MATLAB 2018B PORTABLE
Scientific Linux version 7 so that the compiled binaries are portable on OSG machines. We recommend theĬompilation of your matlab program against matlab versions that match the OSG modules (or containers, with the compilation executed on a server with MATLAB Runtime is availableĪlthough the compiled binaries are portable, they need to have a compatible, OS-specific matlab runtime to interpret the binary. We assume you have access to a server that has MATLAB compiler because the compiler is not available on OSG Connect. For more details, check the list of supported toolboxesĪll applications created with MATLAB Compiler use MATLAB Compiler Runtime™ (MCR), which enables royalty-free deployment and use. The compiler supports most toolboxes and user-developed The MATLAB Compiler™ lets you share MATLAB programs as standalone applications. MATLAB® is a licensed high level language and modeling toolkit.
