MATLAB: Variable MCR_CACHE_SIZE

compileddeployMATLAB Compiler

Hello,

I would like to know the exact purpose of the variable MCR_CACHE_SIZE? My compiled app is around 40 Mb. I have read that the default MCR_CACHE_SIZE is 32 Mb. Does this mean that I need to set the MCR_CACHE_SIZE to a greater value to avoid issues during execution? If I need to increase the cache size, what is the syntax? set MCR_CACHE_SIZE="64Mb"?

Thx in advance,

Luc Masset

Hello Deepak,

Thank you for your answer. Eventually I set the variable MCR_CACHE_SIZE to 64 Mb in the command file used to launch the executable (set MCR_CACHE_SIZE=67108864). However I have also tested a value of 2 (2 bytes) and it does not seem to change anything.

Regards,

Luc

MATLAB: How to resolve issues associated with MATLAB Compiler Runtime cache corruption

Delete the “mcrCache” folder used by the application and rerun the application.The “mcrCache” folder can be located by executing the following command in MATLAB Command window:

mcrcachedir

Note that “mcrCache” folders have the form “mcrCacheX.Y,” where X and Y indicate MATLAB Compiler Runtime (MCR) version. The “mcrCacheX.Y” output by the above command may not correspond to the version of the “mcrCache” folder used by your application.

Delete the “mcrCacheX.Y” folder used by the application. If you are unsure of which “mcrCacheX.Y” is used by your application, delete all folders of the form “mcrCacheX.Y” in the parent directory of the location returned by “mcrcachedir.”

For example, on my machine, “mcrcachedir” returns:C:\Users\Username\AppData\Local\Temp\Parth\mcrCache9.8

But the parent directory “C:\Users\Username\AppData\Local\Temp\Parth” contains folders “mcrCache9.1” and “mcrCache9.8.” Once you delete the appropriate “mcrCache” folder(s), try rerunning your application.

Alternatively, try changing the location of the “mcrCache” folder by typing the following into the Windows Command Prompt:

set MCR_CACHE_ROOT=<accessible_directory>

Where <accessible_directory> is some easy-to-find directory that you have the permission to modify (e.g. the Desktop). Then rerun the application from within the Windows Command Prompt by navigating to its directory and typing the application name in the same Windows Command Prompt.

Applications built using the MATLAB Compiler 4.11 (R2009b) have a default size threshold (32 mb), at which the application runs but will clean up its resource files after runtime. Specifically this would also delete the preferences in the cache directory. You can set this limit higher using the MCR_CACHE_SIZE environment variable, after deleting the .max_size file in the current cache directory (which can be found by executing the following at the MATLAB command prompt

mcrcachedir
