And, FMA instructions often have lower latency than a multiply followed by an add instruction. On the Xbox 360 CPU the latency and throughput of FMA was the same as for fmul or fadd so using an FMA instead of an fmul followed by a dependent fadd would halve the latency. Discussion on reddit/r/programming. Emulating FMA.

This is because they are able to leverage free AWS or Azure startup hosting credits secured through their incubator, accelerator, or startup community program, and can apply their free credits to their database hosting costs as ScaleGrid. Deploying your application and database on the same VPC also provides the lowest possible latency path.

The Morning Paper

DECEMBER 8, 2019

On the last morning of the conference Daniel Bittman presented some of the work being done in the context of the Twizzler OS project to explore new programming models for NVM. The starting point is a set of three asumptions for an NVM-based programming model: Compared to traditional persistent media, NVM is fast. What about security?

This is an intellectually challenging and labor-intensive exercise, requiring detailed review of the published details of each of the components of the system, and usually requiring significant “detective work” (using customized microbenchmarks, hardware performance counter analysis, and creative thinking) to fill in the gaps.

Software today is not typically a single program—something that is executed by an operator or user, producing a result to that person—but rather a service : something that runs for the benefit of its consumers, a provider of value. The most common programming task in the world. Let’s dive into this concept for a bit.

There was no deep goal — just a desire to see the maximum GFLOPS in action. The exercise seemed simple enough — just fix one item in the Colfax code and we should be finished. Using the minimum number of accumulator registers needed to tolerate the pipeline latency (12), the assembly code for the inner loop is: B1.8:

The Agile Manager

DECEMBER 17, 2008

Traditional IT projects are mass economy-of-scale exercises: once development begins, armies of developers are unleashed. But of bigger concern is the latency between the time when requirements are captured and the time they're available as working code in an environment. An Agile team is not an exercise in scale.
