Summary form only given, as follows. A record of the panel discussion was not made available for publication as part of the conference proceedings. Hyperscale ethernet data centers (HEDCs) based on pure ethernet switching have come to dominate both the market and the conversation, and many think they are all that is necessary. But for many years specialized designs for HPC have survived, though these...

Interconnection networks must meet the communication demands of current High-Performance Computing systems. In order to interconnect efficiently the end nodes of these systems with a good performance-to-cost ratio, new network topologies have been proposed in the last years that leverage high-radix switches, such as Slim Fly. Adversarial traffic patterns, however, may reduce severely the performance...
The network plays a key role in High-Performance Computing (HPC) system efficiency. Unfortunately, current HPC routing solutions are not application-aware, and therefore cannot deal with the sudden HPC traffic bursts and their resulting congestion peaks.To address this problem, we introduce Routing Keys, a scalable routing paradigm for HPC networks that decouples intra- and inter-application flow...
The advent of non-volatile memory (NVM) technologies has added an interesting nuance to the node level memory hierarchy. With modern 100 Gb/s networks, the NVM tier of storage can often be slower than the high performance network in the system; thus, a new challenge arises in the datacenter. Whereas prior efforts have studied the impacts of multiple sources targeting one node (i.e., incast) and have...
In this work, we present WaveLight, a monolithic silicon-photonics platform whereby a low latency reliable deterministic protocol with optical functions are designed directly into an existing high-volume CMOS process.
FPGAs (Field Programmable Gate Arrays) are making their way into data centers (DC). They are used as accelerators to boost the compute power of individual server nodes and to improve the overall power efficiency. Meanwhile, DC infrastructures are being redesigned to pack ever more compute capacity into the same volume and power envelopes. This redesign leads to the disaggregation of the server and...
Throughput performance, an important metric for interconnection networks, is often quantified by the aggregate throughput for a set of representative traffic patterns. A number of models have been developed to estimate the aggregate throughput for a given traffic pattern on an interconnection network. Since all of the models predict the same property of interconnection networks, ideally, they should...
Meeting the exponential increase in the global demand for bandwidth has become a major concern for today's data centers. The scalability of any data center is defined by the maximum capacity and port count of the switching devices it employs, limited by total pin bandwidth on current electronic switch ASICs. Optical switches can provide higher capacity and port counts, and hence, can be used to transform...
