 Main achievements

Author of the CDC 7600 Job Scheduler & Integrated Tape Staging Utility (FIND).

These, as well as other, so called, “CERN mods”, have been in wide use in the very restricted supercomputer community around the world during the CDC 7600 era.

Close involvement in numerous system performance and network traffic studies.

Key role in central IBM systems deployment (e.g. HSM, JES2, MSS, Wylbur).

Responsibility for the adaptation of PC based IP gateways for LEP controls.

Key role in EARN/BITNET and electronic mail deployment.

Key role in the deployment of HEPnet and TCP/IP (Internet) communications.

CERN Project Team Leader for the European Union project BETEL (Broadband Exchange over Trans-European Links) - 1993.

Participation to the European Union projects BETEUS (Broadband Exchange for Trans-European Usage) and STEN (Scientific Trans-European Networks) - (1994-1995).

Participation to the Geneva-MAN (155 Mb/s ATM based Metropolitan Area Network) - (1995-1996).

Chairman US Line consortium (USLIC). Since 1995, CERN, IN2P3, US DoE through Caltech, HEPnet Canada through Carleton University and World Health Organization (WHO), decided to organize their Global Internet connectivity through the USLIC in order to benefit from economy of scales. The USLIC successfully managed numerous upgrades of the CERN-USA links from 1.5Mbps in 1995 to 10Gbps in 2003 (i.e. almost a factor 1000 in less than 10 years).

Co-founder of the CERN Internet Exchange Point (CIXP). The rapid deployment of the CIXP is the main reason that led more than 14 Telecom Operators to have presence at CERN, bringing an estimated number of over 1000 strands of fibre in the computer centre, which is very important for present and future LHC networking needs.
