In the back to basics readings this week I am re-reading a paper from 1995 about the work that I did together with Thorsten on solving the problem of end-to-end low-latency communication on high-speed networks. The lack of low-latency made that distributed systems (e.g.

To me this positions Fugaku as the first of a new mainstream, rather than a special purpose system. I have always been particularly interested in the interconnects and protocols used to create clusters, and the latency and bandwidth of the various offerings that are available.

All of the SPECfp_rate2000 results were downloaded from www.spec.org, the results were sorted by processor type, and “peak floating-point operations per cycle” was manually added for each processor type. This includes all architectures, all compilers, all operating systems, and all system configurations.

This is a standalone software program which doesn’t depend on any internet connectivity for its working and its performance is not impacted because of any network related latencies. Any network-related latencies result in performance hindrances in these types of applications.

High-speed networks through 5G may represent the next generation of cord cutting. I don’t need more bandwidth for video conferences or movies, but I would like to be able to download operating system updates and other large items in seconds rather than minutes. Reliability will be an even bigger problem than latency.

Nowadays, the source code to old operating systems can also be found online. For everyone familiar with other operating systems and their CPU load averages, including this state is at first deeply confusing. **Why?** One system with a ratio of 1.5 Latency was acceptable and no one complained.

Microarchitectural timing channels result from competition for hardware resources that are functionally transparent to software… the [ISA] abstraction leaks, as it affects observable execution speed, leading to timing channels. Enforcement of a system’s security policy must not depend on correct application behaviour.

With a far memory tier in place operators can choose between packing more jobs onto each machine, or reducing the DRAM capacity, both of which lead to TCO reductions. This boils down to a single digit µs latency toleration in the tail for far memory, and in addition to security and privacy concerns, rules out remote memory solutions.

However in the Skylake microarchitecture (you can see a list of CPUs here ) the PAUSE instruction changed and in the documentation it says “the latency of the PAUSE instruction in prior generation microarchitectures is about 10 cycles, whereas in Skylake microarchitecture it has been extended to as many as 140 cycles.”

You need a business stakeholder buy-in, and to get it, you need to establish a case study on how speed benefits metrics and Key Performance Indicators ( KPIs ) they care about. Note : If you use Page Speed Insights (no, it isn’t deprecated), you can get CrUX performance data for specific pages instead of just the aggregates.

Many high-end disk subsystems provide high-speed cache facilities to reduce the latency of read and write operations. SQL Server always checks I/O completion status for any operating system error conditions and proper data transfer size and then handles errors appropriately.
