AMD Ryzen Threadripper 3970X / 3960X Linux Benchmarks

Phoronix - Mon, 11/25/2019 - 22:00
After the embargo on the Intel Core i9 10980XE expired a few hours ago, now we are allowed to share the performance numbers on the new AMD Ryzen Threadripper 3960X and 3970X processors. These new Zen 2 HEDT CPUs pack a real performance punch, but do come in as more expensive than the i9-10980XE and there is one boot-stopping Linux bug to mention with a workaround... But besides that lone Linux support caveat, the Threadripper 3960X and Threadripper 3970X absolutely dominate in performance.

The Workaround To Boot Linux On AMD Threadripper 3960X/3970X Systems

Phoronix - Mon, 11/25/2019 - 22:00
As outlined in our AMD Ryzen Threadripper 3960X / 3970X Linux review, these new Zen 2 Threadripper processors are phenomenal processors that offer significant uplift over earlier Threadripper CPUs and easily dominate over Intel's Core i9 HEDT competition. But there is one big issue right now with the Linux support: on Ubuntu and the like, it doesn't boot without a workaround. Here's that workaround for easy future reference...

My top 5 Ansible modules

When I was growing up, my grandfather had a shed in his garden. He would spend hours in there, making and fixing things. This was way before we had the internet, so I spent a lot of time studying him creating things in that shed. Although the shed was full of many tools, from drills to lathes to electrical gubbins and lots of things I doubt I could identify even today, he made use of only a tiny subset of what he had at hand. Yet there never seemed to be limits to what he could achieve.

How to use loops in awk

opensource.com - Mon, 11/25/2019 - 16:01

Awk scripts have three main sections: the optional BEGIN and END functions and the functions you write that are executed on each record. In a way, the main body of an awk script is a loop, because the commands in the functions run for each record. However, sometimes you want to run commands on a record more than once, and for that to happen, you must write a loop.

There are several kinds of loops, each serving a unique purpose.
