Abstract: Conventional high performance computer connections are electron-based systems, which require the memory packages to be as close as mechanically possible to the computation engine. Low power and high bandwidth long distance communication, e.g. photonic or electronic, links can drastically change the architecture of high-performance computers by eliminating the bottlenecks in communication. A computer system comprises: a plurality of memory aggregation devices configured to retrieve data from and store data in a plurality of random access memory modules forming a unified contiguous memory address space disaggregated from a processing unit; one or more computational devices configured for simultaneously launching a plurality of data signals including memory read and/or write requests for the data to the plurality of memory aggregation devices; and a plurality of communication links coupling each of the plurality of memory aggregation devices to each of the one or more computational devices for transferring the data therebetween.
