Multi-resource sharings among virtual machines (VM)are very important in data center, but also bring contentions for cache, disk and network in host server. Recent studies focus primarily on locally optimizing resource sharings in a single server, or global optimization of mitigating cache and memory contentions. But it remains an open question how to efficiently find optimal co-schedules for cache,...
Real-time performance is one of the most essential requirements in the field of Real-Time Operating System (RTOS). Meeting deadlines of the periodic tasks and optimizing response time of non-periodic tasks both are important reflections of high real-time performance. This paper analyzes the deficiency at real-time and schedulable performance of AUTOSAR Operating System (AUTOSAR OS) version 3.1.1....
OSEK/VDX is an important specification in the field of automotive electronics and OSEK COM specifies the data communication behaviors inter-ECU and intra-ECU, but doesn't appoint specific underlying layer. In this paper,OSEK COM is implemented based on CAN bus. We present a model that dynamically generates properly CAN identifier to schedule I-PDUs of OSEK COM and transmit data that is longer than...
An improved ant colony optimization (ACO) was developed based on the characteristics of resource-constrained project scheduling problem (RCPSP). In the algorithm, a new permutation of priorities-based encoding scheme is employed, and the summation evaluation is applied to direct the moving of ants. The priority rule pool, in which lots of priority rules can be managed, is presented to strengthen the...
