CPU resource limits will now be enforced on Tensor. CPU usage will be monitored during the lifetime of each job and if the average CPU load exceeds the requested value of ncpus by 50% then the job will be automatically killed.
For example, if a job requests ncpus=1 but it actually uses eight cores then the job will end prematurely with a warning similar to the following:
PBS: job killed: ncpus 7.37 exceeded limit 1 (sum)
It is particularly easy to consume too many CPUs when using MATLAB because all versions of MATLAB since 2008a have multithreading enabled by default. Consequently, you may not be aware that your MATLAB job is using more than one CPU. Please consult the MATLAB documentation for further information on implicit multithreading.

-a Add to Archive
Add a file to the CTF archive. Use
-a filename
to specify a file to be directly added to the CTF archive. Multiple -a options are permitted. MATLAB Compiler looks for these files on the MATLAB path, so specifying the full path name is optional. These files are not passed to mbuild, so you can include files such as data files.
If only a folder name is included with the -a option, the entire contents of that folder are added recursively to the CTF archive. For example:
mcc -m hello.m -a ./testdir
In this example, testdir is a folder in the current working folder. All files in testdir, as well as all files in subfolders of testdir, are added to the CTF archive, and the folder subtree in testdir is preserved in the CTF archive.
If a wildcard pattern is included in the file name, only the files in the folder that match the pattern are added to the CTF archive and subfolders of the given path are not processed recursively. For example:
mcc -m hello.m -a ./testdir/*
In this example, all files in ./testdir are added to the CTF archive and subfolders under ./testdir are not processed recursively.
mcc -m hello.m -a ./testdir/*.m
In this example, all files with the extension .m under ./testdir are added to the CTF archive and subfolders of ./testdir are not processed recursively.
All files added to the CTF archive using -a (including those that match a wildcard pattern or appear under a folder specified using -a) that do not appear on the MATLAB path at the time of compilation will cause a path entry to be added to the deployed application's run-time path so that they will appear on the path when the deployed application or component is executed.
When files are included, the absolute path for the DLL and header files is changed. The files are placed in the .\exe_mcr\ folder when the CTF file is expanded. The file is not placed in the local folder. This folder gets created from the CTF file the first time the EXE file is executed. The isdeployed function is provided to help you accommodate this difference in deployed mode.
The -a switch also creates a .auth file for authorization purposes. It ensures that the executable looks for the DLL- and H-files in the exe_mcr\exe folder.
example: mcc -R -singleCompThread -m -v ProjClassify2.m -a ./gridworld
