Kernel 3.18: Bulk Network Packet Transmission

Wire-speed and beyond, oh wait

A recent twitter post by Chris Samuel ‏@chris_bloke pointed out some optimizations in Linux networking. Over at LWN.net there is an article explaining Bulk network packet transmission. The comments are worth reading as well, including this blog post by Jesper Dangaard Brouer.

HPC500 Members Get In-Depth Look at 2014 HPC Software Environment Market Data

Addison Snell of Intersect360 Research presented the firm’s findings on HPC Software Environments in 2014 to the members of the HPC500, an elite user group of organizations that represent a worldwide, diverse collection of established HPC professionals from a cross-section of academic, government, and commercial organizations.

The presentation drew on findings from several different reports. Intersect360 Research recently released two HPC User Site Census reports, one on applications and one on middleware. The reports examined the supplier, products, and primary usage of the application software and middleware reported at a number of sites over the previous year. The presentation also included findings from the research firm’s annual HPC user budget map, which tracks spending patterns and shows a percent of spending by category, as well as from a special study on “The Big Data Opportunity for HPC,” which surveyed both HPC and non-HPC enterprises (through a partnership with Gabriel Consulting) on Big Data applications and infrastructures.

How Fast Can You Use a Petabyte of Storage?

A petabyte of space should be enough for anybody

Quick, you just got a petabyte of storage, how fast can you fill it? And once it is full how fast can you dump it. If you estimated anything more than 14 hours, then you are too slow. Way too slow. By combining well designed hardware and BeeGFS (f.k.a. FhGFS) you get the Scalable Informatics FastPath Unison storage appliance. A big chunk of storage that delivers 20 gigabytes/sec (sustained). You can learn a more details from the interview on Inside HP.

Solving the Industry HPC Challange

Free HPC secrets! Your key to success!

The Council on Competitiveness recently released Solve. The Exascale Effect: the Benefits of Supercomputing Investment for U.S. Industry (pdf). As the federal government pursues exascale computing to achieve national security and science missions, Solve examines how U.S.-based companies also benefit from leading edge computation and new technologies first funded by government.

In Case You Were Wondering: Apache Spark, Hadoop, and HPC

Moving beyond MapReduce, if that is your cup of tea

Recently Hadoop distribution provider Hortonworks, announced it was Extending Spark on YARN for Enterprise Hadoop. If you are not up to speed in the Hadoop world there are a few points of interest for HPC in this announcement. First, while Hadoop version 1 was synonymous with MapReduce, Hadoop version 2 has "demoted" MapReduce to an application framework that runs under the YARN (Yet Another Resource Scheduler) resource manager. Thus, Hadoop version 2 has opened up a Hadoop Cluster to many more applications other than MapReduce.
