Shredder is " a low-latency multi-tenant cloud store that allows small units of computation to be performed directly within storage nodes. " " Running end-user compute inside the datastore is not without its challenges of course. V8 is lightweight enough that it can easily support thousands of concurrent tenants.

Edge servers are the middle ground – more compute power than a mobile device, but with latency of just a few ms. These use their regression models to estimate processing time (which will depend on the hardware available, current load, etc.). This could of course be a local worker on the mobile device.

The short answers are, of course ‘all the time’ and ‘everyone’, but this mutual disownership is a common reason why performance often gets overlooked. Of course, it is impossible to fix (or even find) every performance issue during the development phase. Unfortunately, most issues do not get captured at this point. Who: Engineers.

Byte-addressable non-volatile memory,) NVM will fundamentally change the way hardware interacts, the way operating systems are designed, and the way applications operate on data. Therefore any programming abstraction must be low latency and the kernel needs to be kept off the path of persistent data access as much as possible.

The goal is to produce a low-energy hardware classifier for embedded applications doing local processing of sensor data. Of course analog signalling comes with a whole bunch of challenges of its own, which is one of the reasons we tend to convert to digital. One such possible representation is pure analog signalling.

Knowing when and where an error, downtime, or application latency occurs is a critical factor in limiting the impact to users and customers.

This work is latency critical, because volume IO is blocked until it is complete. And, of course, it is designed to minimise the blast radius of any failures that do occur.

It simulates a link with a 400ms RTT and 400-600Kbps of throughput (plus latency variability and simulated packet loss). Simulated packet loss and variable latency, however, can make benchmarking extremely difficult and slow. Our baseline, then, should probably trade lower throughput/higher-latency for packet loss.

Because we are dealing with network protocols here, we will mainly look at network aspects, of which two are most important: latency and bandwidth. Latency can be roughly defined as the time it takes to send a packet from point A (say, the client) to point B (the server). Two-way latency is often called round-trip time (RTT).
