https://eklausmeier.wordpress.com/2013/10/06/amd-bulldozer-cpu-architecture-overview
Elmar Klausmeier's Weblog. October 6, 2013. AMD Bulldozer CPU Architecture Overview. At the chip level, 8 cores per CPU:. Unfortunately I didn’t find opcode clock cycles on AMD’s website. AMD’s website seems to be almost unmaintained, i.e., lots of dead links. Below are some clock cycles gathered through experiment by Agner Fog. I took the values measured for Bulldozer in Instruction Tables. Due to out-of-order execution. Timings may vary in actual programs. This entry was posted in CPU. Notify me of new...

Elmar Klausmeier's Weblog. December 21, 2013. What is generally better: 64-bit or 32-bit? I was just asked this question and referred to Phoronix: Ubuntu 12.04 LTS: 32-bit vs. 64-bit Performance. Is this excellent web-site run by Michael Larabel. Below is a chart from 2012. Not all charts look this astonishing! This was also true in 2006, see below compilation times. See also Agner Fog: Optimizing software in C. Some key facts from Agner. Added 11-Mar-2016: 64-bit can be more power efficient, see phoroni...

http://blog.manty.net/2014/12/haproxy-as-very-very-overloaded-sslh.html

Anyway, here is the setup, it basically consists of a setup on haproxy but if we want transparency we'll have to add to it a routing and iptables setup, I'll describe here the whole setup. Mangle :PREROUTING ACCEPT :IN...

It forbids compression and r...Anoth...

https://eklausmeier.wordpress.com/2015/01/17/setting-up-slurm-on-multiple-machines
Elmar Klausmeier's Weblog. January 17, 2015. Setting up SLURM on Multiple Machines. Is a job-scheduler for Linux. It is most useful if you have a cluster of computers. But if you only have two or three computers it can be put to good use. SLURM is an acronym for Simple Linux Utility for Resource Management. At Harvard with 2,140 nodes equipped with AMD Opteron 6376 CPUs. Frankfurt’s supercomputer. With 862 compute nodes, each equipped with AMD Opteron 6172 processors, also uses SLURM. Many other HPC.
