Is GPI the Programming Tool for the Future of HPC?
As the programming model du jour for HPC compute clusters, MPI has many limitations in terms of scalability and fault tolerance. With these requirements in mind, researchers at the Fraunhofer Institute have developed a new programming interface called GPI that uses the parallel architecture of high-performance computers with maximum efficiency.
I was trying to solve a calculation and simulation problem related to seismic data,” says Dr. Carsten Lojewski from the Fraunhofer Institute for Industrial Mathematics ITWM. “But existing methods weren’t working. The problems were a lack of scalability, the restriction to bulk-synchronous, two-sided communication, and the lack of fault tolerance. So out of my own curiosity I began to develop a new programming model.”

Securing Your Linux Server
Mark Kedgley has a succinct overview of recommended steps to take to harden a linux server over at Ezine Articles. The article is not all inclusive, but it does contain a fairly good summary. However, the steps recommended should not be taken lightly, and not without understanding exactly what the impact of the modifications will be.
Mark lists nine steps in his recommend process:
- Account Policies
- Access Security
- Secure Boot Only
