ARINC 653 provides a strong isolation mechanism for safety computing fields, such as aircrafts. seL4, a 3rd generation microkernel, was formally verified for its functional correctness and provides a desirable code base for partitioning operating systems. But there is a long way from seL4 to partitioning. We take the first step and focus on the temporal aspect, i.e., implementing a partitioned scheduler...
Cloud resource and its load have dynamic characteristics. To address this challenge, a dynamic self-adaptive evaluation method (termed SDWM) is proposed in this paper. SDWM uses some dynamic evaluation indicators to evaluate resource state more accurately. And it divides the resource load into three states - Overload, Normal and Idle by the self-adaptive threshold. Then it migrates overload resources...
