MATLAB: [HDL Coder] Ridiculous RAM usage + How to activate parallel processing

HDL Coder

On my project, the HDL Coder uses ridiculus amounts of RAM. On my 8GB Windows 10 Notebook, it chews through it until after 3min the graphics crash. Now I got a 132GB CentOS6 Server at hand and 120GB are occupied after 10min. After 30min, the OOM Killer kicks in and kills the MATLAB process, because it uses all memory and SWAP.
  • Is this RAM usage still sane for the HDL Coder?
  • Is there anyway I could limit this RAM usage?
  • Can I somehow activate parallel computing on the HDL Coder? I think on the server, there was only one core used.
I cannot share the code of the project though.

Best Answer

This memory usage is not sane and it is the result of not properly optimized MATLAB code for HDL conversion. I tried to run code, which processes 4K Images as a whole.
I expected the HDL Coder to serialize the Matrix and processing structures, but this has to be done by hand.
Now my Images are processed in little 5x5 windows, and the HDL coder does not even exceed 1GB of RAM during compilation.
