In this paper, we propose and evaluate the experimental implementation of cache coloring for task structures on the Linux kernel 2.4.x. We analyzed the behavior of the scheduler from the viewpoint of memory architecture and found that severe cache conflicts occur in a specific cache line. To solve this issue, we applied cache coloring scheme to task(More)
When metal plates (base metal) are joined each other by welding, the penetration depth in the joining part is one of factors to determine the mechanical strength, as shown in Fig.1. It is important to keep the penetration depth constant regardless of the variation of the gap between the metal plates. In order to directly observe it by using a TV camera,(More)
