Ontario Institute for Cancer Research uses open source clouds to aid cancer research
Canadian cancer researchers claim that by combining open source software with commodity hardware, they can give academics in the field access to public cloud-like resource at 60% less cost than Amazon can offer, and help to accelerate the pace of scientific breakthroughs.
[...]
The resource, launched in 2014, runs exclusively on open source, with OpenStack, Ceph, Ansible and Linux being among the many technologies used to run it, in combination with high-density commodity server hardware.
It comprises 2,600 cores, 18TB of RAM, 7.3PB of storage (managed by Ceph), and 670TB of protected cancer genome data, which is accessed by cancer research teams across several continents for analytics purposes.
Speaking to Computer Weekly at the recent OpenStack Summit in Vancouver, George Mihaiescu, senior cloud architect at OICR, said the Collaboratory was created, in part, to open up access to the data that researchers need to advance the medical community’s understanding of cancer.

Jorge Ferrer on open source, community vs enterprise and UX
Vice President of Engineering at Liferay, Jorge Ferrer, talks to Enterprise Times about managing open source relationships and UX.
Many companies are looking at the benefits of open source but struggle to know how best to approach it. At many conferences, the message seems to be that open source is free. But that’s not the case. Access to the code might be free but there are challenges in taking that software into the enterprise.
For example, does the enterprise allow developers to grab any code they want from repositories and incorporate it into enterprise software? If so, how secure is it? Should they choose a curated open source solution and take that on board? There are also skills questions to be dealt with. Do we know the language? Do we have enough skills to integrate this into our existing code base? Will we have to recruit or retrain our existing developers and at what cost?

GCC 8.1 Now Can Be Used On OpenSolaris-Derived OpenIndiana
The GCC 8.1 stable compiler release that debuted a few weeks ago is now available on OpenIndiana, the Illumos-based OpenSolaris-derived operating system.
Initial tests were a success and now GCC 8.1 has rolled out into the main repository of OpenIndiana, but isn't yet the default system code compiler. The new compiler can be obtained via the gcc-8 developer package.

Motor-Driver Board Maximizes Open-Source 3D-Printer Performance
STMicroelectronics’ EVALSP820-XS motor-driver board brings industrial-control expertise to the RepRap Arduino Mega Pololu Shield (RAMPS) open-source 3D-printer platform, enabling 3D printer makers to unleash the full potential of their machines for faster printing and smoother surface finish. The RAMPS modular platform is making Fused Filament Fabrication (FFF) 3D printing accessible to makers, small businesses, and home users, for fast prototyping, making replacement parts, or education. The Arduino Mega 2560, or Arduino DUE, baseboard provides basic control, ready for users to plug-in their own choice of motor driver, extruder controller, and any other desired functions using Mega-compatible expansion shields.

High-resolution motor-driver board targets open-source 3D-printer
The RAMPS modular platform is making Fused Filament Fabrication (FFF) 3D printing accessible to makers, small businesses, and home users, for fast prototyping, making replacement parts, or education. The Arduino Mega 2560, or Arduino DUE, baseboard provides basic control, ready for users to plug-in their own choice of motor driver, extruder controller, and any other desired functions using Mega-compatible expansion shields. As a plug-and-play expansion board, ST’s EVALSP820-XS can drive RAMPS printers at an unprecedented speed for greatly increased throughput ensuring superior smoothness with microstepping resolution from ½-step to 1/256-step per microstep. Key to this giant leap in 3D-printing performance is ST’s STSPIN820 stepper-driver IC which embeds high-speed motor-control input circuitry and algorithms developed for industrial applications. The 4x4mm QFN package also integrates a 1.5Arms output stage.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
