Abstract
In this article, we test the feature of using a Shared Virtual Memory in OpenCL on Intel Iris Xe and Nvidia GeForce RTX 3060 GPUs. The first of these architectures is integrated into the CPU, so by definition, it uses the same RAM as the CPU. The second one uses a PCI-Express connection to transfer data between computer memory and separate GPU memory. OpenCL Shared Virtual Memory (SVM) feature allows zero-copy mechanisms to use the same address space for the CPU and Accelerator. In this work, the authors test the differences between classical implementations of the FEM numerical integration algorithm on GPU with explicit data sending between CPU and Accelerator and the SVM implementation with the transfer hidden from the user. Research should answer whether the advantages of using a weaker integrated card with faster data transfer will overcome the external graphics card’s connection bottleneck.
