The Linux As The Operating System For Computational Node Of Custom Computing Machine Class System

The paper presents the application of the modified real-time Linux kernel as the operating system for the computational node of CCM (custom computing machine) class parallel system designed to aid the simulations of three-dimensional electromagnetic field. The computational node is the application-specific design optimized for the implementation in the FPGA. It is based on Xilnx VirtexIIPro FPGA equipped with two embedded cores of the PowerPC processors. The presented real-time kernel is designed to run on one of the cores. The paper details the procedure needed to create the kernel customized for the specific architecture of the system. The software packages and tools utilized in the kernel development process are also presented
