MATLAB Compiler Standalone Application hogs memory in Linux

Hi,

I tried compiling a simple script into a standalone application in Linux. When I execute my application, it takes up ~100 MB of my memory.

I tried running multiple instances of the same application, and each takes up ~100 MB. Does the MATLAB Compiler Runtime start a new instance every time I run a compiled application?

Here's what I get when I run top -c in the linux console (Compiled application is MCRtest) :

Cpu(s):  3.3%us,  1.0%sy,  0.0%ni, 95.0%id,  0.7%wa,  0.0%hi,  0.0%si,  0.0%st

And here's the test code I used to compile:

    t = 0:10;

    y2 = 1.1.^t; % 10% growth
    plot(t, y2)
    value1 = y2(2);

    % Finding time when value1 doubles
    x = log(2*value1)/log(value1);

    % The value doubles every x amount of time.
    t_n = (1:10)*x;
    y_n = 1.1.^t_n;

    plot(t_n,y_n)

My system (VM Ware system):

    Processor: 1.6Ghz i7 (Single core on VM)
    Memory: 1 GiB
    OS: Linux Mint 10

Is anyone experiencing the same thing? Is there any way I can reduce the memory footprint?

Thanks in advance.

Does *bump* work here?

Yes, it does. :)

Yes, I do believe that a new instance of the MCR is started for every instance of the compiled executable. That is what is likely taking the 100MB.
