The design of Cedar is to support multiple simultaneous parallel jobs of up to 1024 cores in a fully non-blocking manner. For larger jobs the interconnect has a 2:1 blocking factor, i.e., even for jobs running on several thousand cores the Cedar system provides a high-performance interconnect. | The design of Cedar is to support multiple simultaneous parallel jobs of up to 1024 cores in a fully non-blocking manner.
