A first sled can comprise the physical compute resources and a first set of physical memory resources while a second sled can comprise a second set of physical memory resources. The first set of physical memory resources can be coupled to the physical compute resources via a local interface while the second set of physical memory resources can be coupled to the physical compute resources via a fabric.

Technologies for adaptive processing of multiple buffers is disclosed. A compute device may establish a buffer queue to which applications can submit buffers to be processed, such as by hashing the submitted buffers. The compute device monitors the buffer queue and determines an efficient way of processing the buffer queue based on the number of buffers present. The compute device may process the buffers serially with a single processor core of the compute device or may process the buffers in parallel with single-instruction, multiple data (SIMD) instructions. The compute device may determine which method to use based on a comparison of the throughput of serially processing the buffers as compared to parallel processing the buffers, which may depend on the number of buffers in the buffer queue.

A station placed on a high-altitude stationary platform includes two main emitter/receiver sets, each configured to establish a main communication link with a remote terminal station or with another station placed on a high-altitude stationary platform and two backup emitter/receiver sets, each configured to establish a backup communication link with a repeater placed on a relay station on the ground or at sea or with a remote terminal station, the station furthermore comprising a control facility configured to selectively activate a main communication link or a backup communication link as a function of an indicator of the operating state of the main communication link.
