Adapting InfiniBand for High Performance Cloud Computing

When it comes to low-latency interconnects for high performance computing, InfiniBand immediately springs to mind. On the most recent Top 500 list, over 37% of systems used some form of InfiniBand – the highest representation of any interconnect family. Since 2009, InfiniBand has occupied between 30 and 51 percent of every Top 500 list.

But when you look to the clouds, InfiniBand is hard to find. Of the three major public cloud offerings (Amazon Web Services, Google Cloud, and Microsoft Azure), only Azure currently has an InfiniBand offering. Some smaller players do as well (Profit Bricks, for example), but it’s …

Wouldn’t it be nice if everyone knew a little queuing theory?

After many days of rain one lane of this two lane road collapsed into the canyon. It's been out for a month and it will be many more months before it will be fixed. Thanks to Google maps way too many drivers take this once sleepy local road. 

How do you think drivers go through this chokepoint? 

 

 

One hundred experience points to you if you answered one at a time.

One at a time! Through a half-duplex pipe following a first in first out discipline takes forever!

Yes, there is a stop sign. And people default to this mode because it appeals to our innate sense of fairness. What could be fairer than alternating one at a time?

The problem is it's stupid.

While waiting, stewing, growing angrier, I often think if people just knew a little queueing theory we could all be on our way a lot faster.

We can't make the pipe full duplex, so that's out. Let's assume there's no priority involved, vehicles are roughly the same size and take roughly the same time to transit the network. Then what do you do?

Why can't people figure out its faster to drive through Continue reading

IDG Contributor Network: The sky is streaming

Internet access has gone through several generations that started with dial-up modems. I still remember my “blazing fast” upgrade from 24 kbps to 56 kbps.Dial-up modems gave way to always-on broadband solutions. Initially there were two choices: Cable (DOCSIS) and telephone (DSL). Wireless (LTE) has emerged over the past few years as a viable option for connectivity beyond smartphones.Many investors think the next generation will be wireless connectivity. It’s unfortunate that “Skynet” is associated with the villainous, fictional neural machines from the Terminator movies because each of these solutions will deliver the internet from the sky. After all, the sky is where the clouds are.To read this article in full or to leave a comment, please click here

25 most common passwords in 2016 and how quickly they can be cracked

On Premises Object Storage Mimics Big Public Clouds

Object storage is not a new concept, but this type of storage architecture is beginning to garner more attention from large organisations as they grapple with the difficulties of managing increasingly large volumes of unstructured data gathered from applications, social media, and a myriad other sources.

The properties of object-based storage systems mean that they can scale easily to handle hundreds or even thousands of petabytes of capacity if required. Throw in the fact that object storage can be less costly in terms of management overhead (somewhere around 20 percent so that means needing to buy 20 percent less capacity …

Why Linux users should worry about malware and what they can do about it

Preventing the spread of malware and/or dealing with the consequences of infection are a fact of life when using computers. If you’ve migrated to Linux or Mac seeking refuge from the never-ending stream of threats that seems to target Windows, you can breath a lungful of fresh air—just don’t let your guard down.Though UNIX-like systems such as Mac OS X and Linux can claim fewer threats due to their smaller user bases, threats do still exist. Viruses can be the least of your problem too. Ransomware, like the recent version of KillDisk, attacks your data and asks you to pay, well, a king’s ransom to save your files. (In the case of KillDisk, even paying the ransom can’t save you if you’re running Linux.)To read this article in full or to leave a comment, please click here
