Compress objects, not cache lines: an object-based compressed memory hierarchy

The Morning Paper

Compress objects, not cache lines: an object-based compressed memory hierarchy Tsai & Sanchez, ASPLOS’19. Existing cache and main memory compression techniques compress data in small fixed-size blocks, typically cache lines. These techniques work well for scientific programs that are dominated by arrays.

Predictive CPU isolation of containers at Netflix

The Netflix TechBlog

Because microprocessors are so fast, computer architecture design has evolved towards adding various levels of caching between compute units and the main memory, in order to hide the latency of bringing the bits to the brains. This avoids thrashing caches too much for B and evens out the pressure on the L3 caches of the machine.

From Heavy Metal to Irrational Exuberance

ACM Sigarch

These, let’s call them metal languages , include FORTRAN (introduced in 1957), C (1972), and C++ (1985). Programmers continue to write applications in them, and they continue to evolve: the just approved C++20 standard is the latest example. Despite their age, these languages are far from dead! As Leiserson et al.

HammerDB for Managers

HammerDB

It enables the user to measure database performance and make comparative judgements about database hardware and software. These factors meant that often when looking for database performance information, the results for a particular combination of software and hardware were not available. What is HammerDB? Why HammerDB was developed.
