Enable use of memory manager

Since R2021b

Model Configuration Pane: Code Generation / GPU Code

Description

The Memory Manager parameter specifies whether to use GPU memory manager for memory allocation and management. Using GPU memory manager reduces the number of memory allocation calls and improves run-time performance.

Dependencies

The GPU memory manager creates a collection of large GPU memory pools and manages allocation and deallocation of chunks of memory blocks within these pools. By creating large memory pools, the memory manager reduces the number of calls to the CUDA® memory APIs, improving run-time performance. You can use the GPU memory manager for MEX and standalone CUDA code generation.
