“Containers wrap up software with all its dependencies in packages that can be executed anywhere. This can be specially useful in HPC environments where, often, getting the right combination of software tools to build applications is a daunting task.”
“High performance computing has begun scaling beyond Petaflop performance towards the Exaflop mark. One of the major concerns throughout the development toward such performance capability is scalability – at the component level, system level, middleware and the application level.
FlyElephant announced a number of upgrades that allow users to work with private repositories with an improved system security and good task functionality, including public API and improved logging. “FlyElephant is a platform for scientists, providing a computing infrastructure for calculations, helping to find partners for the collaboration on projects…
Today ThinkParQ announced that the complete BeeGFS parallel file system is now available as open source. Developed specifically for performance-critical environments, the BeeGFS parallel file system was developed with a strong focus on easy installation and high flexibility, including converged setups where storage servers are also used for compute jobs.
Short answer: Yes, but it’s more complicated than that. We have been following D-Wave’s claims about its quantum hardware at Ars for a number of years. Over that time, my impression has oscillated between skepticism, strong skepticism, and mild enthusiasm.
OpenMP is basically fine-grained, in that parallel parts of the application are created and destroyed multiple times throughout a run…. MPI is generally a coarse-grained, as the parallelism where MPI is used would be higher up in the algorithm.
This visualization from CSCS in Switzerland shows the world’s smallest integrated switch. “Researchers working under Juerg Leuthold, Professor of Photonics and Communications at ETH Zurich, have created the world’s smallest integrated optical switch.
Today the European Consortium announced a step towards Exascale computing with the ExaNeSt project. Funded by the Horizon 2020 initiative, ExaNeSt plans to build its first straw man prototype in 2016.
Log data provides critical insights into software systems. However, in the age of ubiquitous computing, unifying logs from hundreds of data sources with different formats presents a big challenge.
The Linux Foundation, the nonprofit organization dedicated to accelerating the growth of Linux and collaborative development, today announced the DiaMon workgroup, which is creating a de-facto standard for tracing and monitoring infrastructure in order to improve diagnostics of Linux user space programs.
