Choose a Parallel Computing Solution

Process your data faster or scale up your big data computation using the capabilities of MATLAB^®, Parallel Computing Toolbox™ and MATLAB Parallel Server™.

Problem	Solutions	Required Products	More Information
Do you want to process your data faster?	Profile your code.	MATLAB	Profile Your Code to Improve Performance
	Vectorize your code.	MATLAB	Vectorization
	Use automatic parallel computing support in MathWorks products.	MATLAB Parallel Computing Toolbox	Run MATLAB Functions with Automatic Parallel Support
	If you have a GPU, try `gpuArray`.	MATLAB Parallel Computing Toolbox	Run MATLAB Functions on a GPU
	Use `parfor`.	MATLAB Parallel Computing Toolbox	Interactively Run Loops in Parallel Using parfor
Do you want to speed up simulations?	Use `parsim`.	Simulink^® Parallel Computing Toolbox	Running Multiple Simulations (Simulink)
