    Abstract: A technique includes generating a checkpoint for an application that is executing on a plurality of nodes of a distributed computing system. Forming the checkpoint includes selectively regulating communication of data from the plurality of nodes to a storage subsystem based at least in part on a replication of the data among the nodes.

    Abstract: Various embodiments of the present invention are directed to methods and systems for transmitting optical signals from a source to a plurality of receiving devices. In one method embodiment, an optical enablement signal is transmitted from the source to the plurality of receiving devices. The target receiving device responds to receiving the optical enablement signal by preparing to receive one or more optical data signals. The source transmits the one or more optical data signals to the target receiving device. The remaining receiving devices do not receive the one or more optical data signals.

    Abstract: A system can include an optical multiplexer to combine a plurality of optical input signals having respective wavelengths into a wide-channel optical input signal that is provided to an input channel. The system also includes a photonic packet switch comprising a switch core and a plurality of ports defining a switch radix of the photonic packet switch. The input channel and an output channel can be associated with one of the plurality of ports. The photonic packet switch can process the wide-channel optical input signal and can generate a wide-channel optical output signal that is provided to the output channel. The system further includes an optical demultiplexer to separate the wide-channel optical output signal into a plurality of optical output signals having respective wavelengths. The optical multiplexer and the optical demultiplexer can collectively provide the system with a radix greater than the switch radix.

    Abstract: A blade includes a circuit board to insert into a slot of a chassis, an optoelectronic device on the circuit board, an optical media that is flexible, coupled to the optoelectronic device, and able to guide a plurality of optical signals, a first connector optically coupled to the optical media, and a standoff on which the first connector is mounted. The first connector includes first alignment features shaped to mate with second alignment features of a second connector. The standoff provides the first connector with sufficient freedom of motion to permit the first alignment features to shift the first connector relative to the second connector and into a seated position as the first connector and the second connector move toward each other.
