When I started learning Python, I was looking for a programming language that would replace BASH, AWK and SED. I am a C/C++ programmer and as such I better invest my time into studying C and C++. Instead, every time I needed some complex script I opened up a book on BASH and refreshed my […]
When considering ways to spread interrupts from one device among multiple cores, I can’t not to mention MSI-X. The thing is that MSI-X is actually the right way to do the job. Interrupt affinity, which I discussed here and here, has a fundamental problem. That is inevitable CPU cache misses. To emphasise this, think about […]
One of the features of x86 architecture is ability to spread interrupts evenly among multiple cores. Benefits of such configuration seems to be obvious. Interrupts consume CPU time and by spreading them on all cores we avoid bottle-necks. I’ve written an article explaining this mechanism in greater detail. Yet let me remind you how it […]
