Spinning the Bottleneck for Data, AI, Analytics and Cloud

High performance computing experts came together recently at Stanford for their annual HPC Advisory Council Meeting to share strategies after what has been an interesting year in supercomputing thus far. 

As always, there was a vast amount of material covering everything from interconnects to containerized compute. In the midst of this, The Next Platform noted an obvious and critical thread over the two days–how to best map infrastructure to software in order to reduce “computational back pressure” associated with new “data heavy” AI workloads.

In the “real world” back pressure results from a bottleneck as opposed to desired …

Spinning the Bottleneck for Data, AI, Analytics and Cloud was written by James Cuff at The Next Platform.

Small Giants

I’m sure you’ve all come across the phrase “standing on the shoulders of giants”. Whilst it’s easy to remember or glibly repeat, it’s also easy to forget or ignore the serious message being delivered by those words. To me, the meaning is legion; something as close and personal as my parent’s care (well, of one […]

Packaging an out-of-tree module for Debian with DKMS

DKMS is a framework designed to allow individual kernel modules to be upgraded without changing the whole kernel. It is also very easy to rebuild modules as you upgrade kernels.

On Debian-like systems,1 DKMS enables the installation of various drivers, from ZFS on Linux to VirtualBox kernel modules or NVIDIA drivers. These out-of-tree modules are not distributed as binaries: once installed, they need to be compiled for your current kernel. Everything is done automatically:

# apt install zfs-dkms
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following additional packages will be installed:
  binutils cpp cpp-6 dkms fakeroot gcc gcc-6 gcc-6-base libasan3 libatomic1 libc-dev-bin libc6-dev

New Spectre derivative bug haunts Intel processors

Intel just can’t catch a break these days. Researchers at Ohio State University have found a way to use the Spectre design flaw to break into the SGX secure environment of an Intel CPU to steal information.SGX stands for Software Guard eXtensions. It was first introduced in 2014 and is a mechanism that allows applications to put a ring around sections of memory that blocks other programs, the operating system, or even a hypervisor from accessing it.To read this article in full, please click here

Shine the Light: Six Women Making a Difference

This International Women’s Day, we’re boosting the profiles of incredible women around the world who are pushing boundaries using technology – and we encourage you to do the same!

Last month, during Safer Internet Day – a call to action for everyone to play their part in creating a better Internet for everyone – women in the Internet Society’s 25 Under 25 group, using just their smartphones to record video, answered the question, “What does a safer Internet mean to me?”

Watch the videos, explore the different ways these young women are using technology to shape tomorrow, then Shine The Light on some of the incredible women you know who are making an impact. Join the #ShineTheLight tweet chat with @SIGWomenISOC on March 8th… then join SIG Women!
