We focus on a definition that draws from the following two principles: (1) the value of temporal locality, by classifying as cold a memory page that has not been accessed beyond a threshold of T seconds; (2) a proxy for the application effect of far memory, by measuring the rate of accesses to cold memory pages, called promotion rate.

This is possible because the Tcl interpreter is exceptionally compact and lightweight (Also for this reason Tcl is often used as an embedded language in hardware such as Cisco Routers). Whereas within Python all threads run in a single interpreter (after acquiring the GIL) in Tcl each thread has its own copy of the interpreter. HammerDB GUI.

So we really can’t talk about automating any significant task without seeing it as a non-trivial data integration project: matching IDs, reconciling slightly different definitions of database columns, de-duping, named entity recognition , all of that fun stuff. Is special-purpose training to fine-tune a model’s behavior an option?

Linux has been adding tracing technologies over the years: kprobes (kernel dynamic tracing), uprobes (user-level dynamic tracing), tracepoints (static tracing), and perf_events (profiling and hardware counters). Outside of EC2, many other providers are deploying on KVM. Details in the appended shortlog. [.].

The data shape will dictate capacity planning, tuning of the backbone, and scalability analysis for individual components. They have a clear input and output definition, and often a schema as well. It enables unbounded scalability as more commodity or specialized hardware can be seamlessly added to existing clusters.

While a perfect understanding of these concepts is not needed for the rest of this post, having a common high-level definition would be good. As such, tuning congestion logic is usually only done by a select few developers, and evolution is slow. We can also expect QUIC-specific hardware to become available. Congestion Control.
