Björn Andersson, investigador do Centro de Investigação em Sistemas Confiáveis e de Tempo-Real (CISTER) é o próximo convidado da série de seminários do CISTER. A apresentação "The Utilization Bound of Non-Preemptive Rate-Monotonic Scheduling in Controller Area Networks is 25%" realiza-se no próximo dia 17 de Junho.
"The Utilization Bound of Non-Preemptive Rate-Monotonic Scheduling in Controller Area Networks is 25%"
Consider a distributed computer system comprising many computer nodes, each interconnected with a Controller Area Network (CAN) bus. We prove that if priorities to message streams are assigned using rate-monotonic (RM) and if the requested capacity of the CAN bus does not exceed 25% then all deadlines are met.
Björn Andersson received the M.Sc. and Ph.D. degrees from Chalmers University of Technology, Gothenburg, Sweden, in 1999. He received the SNART best Master of Science thesis award that year.
He extended (together with others) static-priority scheduling from uniprocessors to multiprocessors. He is currently a Research Scientist at CISTER/IPP-Hurray, Porto, Portugal, exploring real-time communication, real-time scheduling on multiprocessors, and data aggregation in cyber-physical computer systems.
