My Linux cluster system uses the latest high speed CPUs. Why is Delta HPCs SMP machine faster than a conventional cluster or massively parallel computer system?
The NUMA architecture of Delta HPC’s system means that the data in memory that constitute a job’s tasks is viewed in its entirety by all processors at once. The connection to this data from the processor and between the processors is extremely fast relative to a Linux cluster. The result is that even with a supercomputer that has slower processors than those in a Linux cluster, the NUMA architecture advantage means that data intensive jobs will be performed much faster than in a Linux cluster system. Specifically, the CC-NUMA systems at Delta HPC utilize SGI’s Scalable Node (SN) architecture. In an SN system, processors, memory, and a bus- and memory-controller are coupled together into an entity known as a node, which is usually a single circuit board. These nodes are connected via a high-speed interconnect. Because there is no internal bus whatsoever, access between processors, memory, and I/O devices is facilitated through a switched fabric of links and routers. This allows the comb
