Heterogeneous and Composable Memory (HCM) offers a feasible solution for terabyte- or petabyte-scale systems, addressing the performance and efficiency demands of emerging big-data applications. CXL-based disaggregated memory provides a new opportunity with two orders of magnitude better performance than RDMA (as illustrated in Figure 2).

One of the big topics at the OpenStack conference was how to prepare and implement a successful transition to 5G. With the 5G revolution, operators will need to manage hundreds of edge deployments, and maintain the physical space and hardware to achieve 1ms of latency. This requires 1 ms network latency.

Virtualization, for instance, was being addressed by IBM in the 1960s. Both virtualization and power burst onto the architecture community seemingly out of nowhere even though there was a clear historical basis and trend for both. At other times, the PC’s response is to push the paper to another conference.

I became the Sun UK local specialist in performance and hardware, and as Sun transitioned from a desktop workstation company to sell high end multiprocessor servers I was helping customers find and fix scalability problems. We had specializations in hardware, operating systems, databases, graphics, etc.

These strange questions came to the fore back in 2014 when Netflix was switching services from CentOS Linux to Ubuntu, and I helped debug several weird performance issues including one I'll describe here. A quick check of basic performance statistics showed over 30% higher CPU consumption. How would you _time_ time?

At the start of November I was privileged to attend HPTS (the High Performance Transaction Systems) conference in Asilomar. 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.

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). As a performance engineer who does kernel tracing, I find the lack of an ID I can trace in the kernel to be pretty annoying.
