It enables the user to measure database performance and make comparative judgements about database hardware and software. Databases are highly sophisticated software, and to design and run a fair benchmark workload is a complex undertaking. What programming languages does HammerDB use and why does it matter?

In fact, according to Stack Overflow’s annual developer survey , JavaScript and Python are now the #1 and #2 most used programming languages, respectively (excluding HTML/CSS and SQL as “programming languages”). To be clear, these languages were not designed to be fast or space-efficient, but for ease of use.

. …software operating on persistent data structures requires "global" pointers that remain valid after a process terminates, while hardware requires that a diverse set of devices all have the same mappings they need for bulk transfers to and from memory, and that they be able to do so for a potentially heterogeneous memory system.

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.

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? MPI is a commonly used standard to implement message-passing programs on computer clusters. The MPI runtime library. in ways that are seldom transparent.

Stable media is commonly physical disk storage, but other devices and certain caching facilities qualify as well. Many high-end disk subsystems provide high-speed cache facilities to reduce the latency of read and write operations. This cache is often supported by a battery-powered backup facility.

In industry, generally due to time-to-market restrictions, we tend to think extremely short term with evolutionary design changes rather than riskier revolutionary ideas that have a longer timeline for returns. I recall heated discussions 20+ years ago on whether speculative data in caches improves or degrades cache performance.

When a Windows program stops pumping messages there will be ETW events emitted to indicate exactly where this happened , so those types of hangs are trivial to find. Normally running every 6 ms is enough to make a program responsive, but for some reason it wasn’t making any progress. But apparently Chrome kept on pumping messages.
