We’re continuously working to support the most popular operating systems with high quality OneAgent deployment options. Because of continuously decreasing and already marginal adoption of 32-bit operating systems we will discontinue support for monitoring of legacy 32-bit operating systems for all Windows and Linux distributions, as of April 2021. Of course, it’s possible to run a legacy 32-bit application on a 64-bit operating system.

” This paper describes a “far memory” system that has been in production deployment at Google since 2016. With a far memory tier in place operators can choose between packing more jobs onto each machine, or reducing the DRAM capacity, both of which lead to TCO reductions. The key to an efficient system is the identification of cold pages: the cold age threshold determines how many seconds we can go without a page being accessed before it is declared cold.

…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. The logical object space is an abstraction over physical memory that contains the working set of actively used objects local to one system.

The paper focuses on two key use cases: A confined component running in its own security domain, connected to the rest of the system by explicit (e.g. “ To avoid the interconnect channel, we have to assume the system either runs on a single core (at least while the sensitive code is executing), or co-schedules domains across the core, such that at any time only one domain executes.
