How to measure GPU memory utilization in Matlab?
To measure GPU memory utilization in MATLAB, you can use the gpuDevice function to get information about the currently selected GPU device. Here's an example code that shows how to measure GPU memory utilization:
1 2 3 4 5 6 7 8 9 10 11 |
% Select the GPU device gpuDevice(1); % Get information about the selected GPU gpuInfo = gpuDevice(); % Access GPU memory utilization memoryUtilization = gpuInfo.MemoryUtilization; % Print the GPU memory utilization disp(['GPU Memory Utilization: ', num2str(memoryUtilization), '%']); |
In this code, gpuDevice(1) selects the first available GPU device. You can change the device number as per your requirement. The gpuDevice function returns a structure containing information about the GPU device, such as its name, total memory, and memory utilization. The MemoryUtilization field of the structure can be accessed to get the GPU memory utilization in percentage. Finally, disp is used to print the GPU memory utilization.
What is the role of GPU memory utilization in Matlab?
The GPU memory utilization in Matlab refers to the amount of memory used by the Graphics Processing Unit (GPU) during the execution of Matlab code. The GPU is a specialized electronic circuit designed to rapidly manipulate and alter memory to accelerate the creation of images in a frame buffer intended for output to a display device.
In Matlab, the GPU memory utilization plays a crucial role when performing computationally intensive operations that can be accelerated using the GPU. By utilizing the GPU's parallel processing capabilities, certain calculations and operations can be significantly faster compared to traditional CPU-based computations.
When executing GPU-accelerated code in Matlab, relevant data is transferred from the main system's RAM to the GPU memory for processing.
