Brief personal presentation

Hi folks!
My name is Vittorio Memmo, I'm a experienced professional from Italy in a wide range of Information Technology products and services.
My expertise is primarly focused on server systems built upon Linux and based on Open Source solutions, thanks not only to my researcher-style cultural background concerning high performance pure-computing environments, but also to my strong on-the-field application capabilities.
Fedora Linux has been a distinctive key point in my professional activity despite the scepticism some customers had shown in favour of commercially oriented Linux and other Unix-like distributions.
Linux can run on almost any platform powering from mythical microcomputer of the '90s to large mainframes and server farms, up to petaflops grade supercomputers with a kernel that can be deeply modified and even rewritten to suit even the most diverse requirements.
Although I'm mainly a self-taught person (yes, I've never attained certification courses and I'm proud of not to be branded a goat!), during my job activity as Field Application Engineer and Pre-sales support specialist at the beginning, then as System Engineer, currently as IT Consultant and Systems Analyst, I’ve achieved many successful objectives leveraging my expertise in researching the solution to problems other persons couldn’t find.

Success stories

Among the others I've realised:

a high performance computing mini-cluster for scientific calculation based entirely on a customized kernel Fedora Linux platform and built upon COTS technologies to Technical Physics Department in the main University of Rome.
The cluster has been realised for both batch and real time execution of custom programs developed by students and researchers in C++ and Fortran programming languages for implementing algorithms that usually require heavy duty calculations in various fields of applied Physics such as Fluid Dynamics and Digital Image processing that would require days or even weeks of execution time on normal equipped workstations.
In the meantime the department researchers can rely on a robust high-availability on-demand central calculation equipment for supporting Grid Mathematica® symbolic processor parallelization capabilities of running more calculation tasks in parallel.

a Nagios® server monitoring about 500 hosts and 1900 services to a Central Government site entirely based on Fedora 10. I've developed shell scripts for integration with the ticketing system (the monitoring system is able to open service requests based on certain detected events) and various customizations to support customer specific needs and to satisfy SLA contract constrains. The result is great: the Fedora 10 based system, the only Fedora in the Italian Government sites , runs rock solid since January 2009 and the monitoring facility is the foundation of the entire system management activity in a so mission critical environment.

Future plans

Presently I'm working on other ideas based on Fedora Linux.
Fedora is my reference Linux distribution. I'm looking forward to continue building Fedora based servers for the customers I'll work for.
Among my most recent projects:

OpenAIS/Corosync-Pacemaker managed HA physical cluster designed for both high availability and power demanding applications running in the physical environment for performance maximizing, while sharing resources with a XEN-virtualized environment dedicated to tests and pre-production simulations.

A Beowulf-style cluster leveraging powerful open-source resource managers and job-schedulers like Torque and Maui, implementing the most recent developments in frameworks, libraries, APIs.

Such projects are being studied by myself in my spare time which unfortunately is becoming more and more restricted in the last times, so people that could work together on such field is welcome!

About the author

Vittorio Memmo was born in Lanciano, a little town located in Abruzzo region nearby the Adriatic Sea.
After having studied Physics in the university of Rome for 6 years specializing in cybernetics and applied electronics,
he started Exin Lab in 2000, a little personal business concerning information technology services
for small and medium enterprise customers.
In the meantime he kept on a deep research activity improving proficiency in HA and MPP clusters as well as GRID
systems for high-performance computing dedicated scientific applications.
He's dedicating many hours of his life to studying, researching, testing, inventing.
Presently he works as a Information Technology Consultant for a big technology company delivering services
for governament, defence and research departments.
