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 communication, e.g. photonic, links can drastically change the architecture of high-performance computers by eliminating the bottlenecks in communication and augment existing memory systems to allow them to be both high capacity and high bandwidth simultaneously. 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; a plurality of 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 plurality of computational devices for transferring the data therebetween.

Abstract: Mixing between I and Q components in coherent homodyne optical signals can occur due to phase shifts, e.g. relative to the local oscillator, relative to the other signal components. In some examples, the phase shifts can arise due to thermal expansion of the optical waveguides and/or can include polarization mixing. A descrambler functions to correct for mixing between multiple signal components. The descrambler may be configured to at least partially correct for a phase difference between a first plurality of modulated optical data signals and a first local oscillator reference signal; and a controller may be configured for determining a first correction parameter for at least partially correcting for the phase difference, and for transmitting the first correction parameter to the descrambler. The controller may be configured for determining the first correction parameter from a first pilot signal transmitted with the first plurality of modulated optical data signals.
