The analysis of the data collected during the tour allowed the computation of a number of statistics regarding system performance (see Table 1). In particular, for each stage of the tour, the average and maximum speeds of the vehicle during automatic driving were computed. Average speed was strongly influenced by the heavy traffic conditions (especially on Torino, Milano and Roma's bypasses) and by the presence of toll stations, junctions and road works.
The automatic driving percentage and maximum distance show high values, despite the presence of many tunnels (particularly during the Appennines routes Ancona to Roma and Firenze to Bologna) and of several stretches of road with absent or worn lane markings (Ferrara to Ancona and Ancona to Roma) or even no lane markings at all (Firenze to Bologna). It is fundamentally important to note that some stages included passing through toll stations and transiting bypasses with heavy traffic and frequent queues, during which the system had to be switched off.
Throughout the entire project, the choice of an Intel-based platform, coupled with the Linux operating system, was shown to be extremely reliable; the number of faults due to these system components was zero over the last two years.
Originally, the main reason behind the choice of the Linux operating system (instead of real-time OS or operating systems for industrial PCs) was the availability of up-to-date developing and debugging tools, drivers and FAQs about specific hardware devices, and the possibility of interacting with a large number of researchers worldwide on the Internet in order to solve problems.
The main topics for future research (ARGO Project, phase II) are related to the development of a new vehicle integrating both road following and platooning (the automatic following of a manually driven vehicle) functionalities. In this next phase, the processing engine will be a higher performance Intel-based architecture, again driven by the Linux operating system.
Practical Task Scheduling Deployment

One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
