According to Dr. Bandwidth, performance analysis has two recurring themes: How fast should this code (or “simple” variations on this code) run on this hardware? The user environment defines the mapping of MPI ranks to hardware resources (cores, sockets, nodes). The MPI runtime library. in ways that are seldom transparent.

It’s why the company has racked up so many industry firsts across transportation, defense and beyond. The first geodetic SECOR satellite surveying system to offer coast-to-coast measurement of the country. And first to invent the “Top Gun” Air Combat Training System back in the early ‘70s. .

16 x 1’s inability to assign requests to idle cores results in higher tail latencies and a peak throughput 25-73% lower than 1 x 16 under a tail latency SLO at 10x the mean service time… The theoretical results suggest that systems should implement a queueing configuration that is as close as possible to a single queue (1 x 16) configuration.

In the past analytics within an organization was the pinnacle of old style IT: a centralized data warehouse running on specialized hardware. With the new BI system the company is able to run analytics across 140 stories per day, in real time, and increase their agility for completing analytics tasks from months to days.

The management consultants at McKinsey expect that the global market for AI-based services, software and hardware will grow annually by 15-25% and reach a volume of around USD 130 billion in 2025. Today we can predict precisely how many shirts in a certain size and color will be sold on a defined day.

Buildings, food and transport have a much bigger carbon footprint than IT globally. In the simplest case, you have a growing workload, and you optimize it to run more efficiently so that you don’t need to buy or rent additional hardware, so your carbon footprint stays the same, but the carbon per transaction or operation is going down.

Recall that Cupertino manages the actual work of Safari engineers through Apple-internal systems (previously named "Radar" ), making public bug reports a sort of parallel track; once an issue is imported from a public bug to a private tracker, it's more likely to get developer attention.

Now welcome to the hardware jungle. First, I don’t agree with the assertion that reliability alone is what’s important, or that it’s more important than latency, for the following reason: You can build reliable transports on top of unreliable ones. We can and do build secure reliable global banking systems on that.

Tools and CI systems help them monitor progress & prevent regressions. Some systems show median RTTs near ~100ms for 3G users. Contended, over-subscribed cells can make “fast” networks brutally slow, transport variance can make TCP much less efficient , and the bursty nature of web traffic works against us.

After finding it cost prohibitive to use colocation centers in local markets where their users are based, iZettle decided to give up hardware. AWS is helping them reach their goal of becoming the leader in sustainable transport. iZettle, a mobile payments startup, is also ‘all-in’ on AWS.

An often used metaphor is that of a pipe used to transport water. One aspect of performance is about how efficiently a transport protocol can use a network’s full (physical) bandwidth (i.e. Passing this data is done using kernel APIs (system calls), which involves a certain amount of overhead per API call.
