Activities & Projects

Description

• ATLAS at CERN

I work on the Trigger/DAQ for the ATLAS Experiment that will run at the LHC collider located at CERN. The work includes:

• Remote Farms
• Protocols in Trigger/DAQ
• Gigabit Ethernet Performance
• SCI Scalable Coherent Interface

• VLBI

Networking issues for transporting Radio Astronomy Very Long Baseline Interferometer data include:

• Comparison of the Performance of Production and UKLight links
• TCP and UDP Comparison
• Mark5 and End-host Performance Tests
• MPhys Project on Packet Loss
• "Proof of Concept" VLBI Transmission Demonstrations at iGrid2002 and ER2002 with Dante

• ESLEA UKLight

• High Throughput
• New Protocols (TCP stacks & DDCP)
• RAID Disk Sub-System Performance
• SC2004 BandWidth Challenge and Demonstrations

• Gigabit Ethernet & NICs

• Network Performance: Latency, Throughput, Jitter, Packet Loss, 1-way delay
• End Host Behaviour: PCI/PCI-X Bus Activity, Memory bus, CPU load, Interrupts
• Motherboards, NICs, TOEs, Switches & Routers

• RAID & Disks

RAID and Disk sub-system tests

• ESLEA RAID Disk Sub-System Performance (SC2004)
• PCI/PCI-X traces
• MB-NG & BarBar Disk Sub-System Performance

• MB-NG

MB-NG is a 2.5 Gbit MPLS development network in the UK provided by UKERNA. As well as investigating QoS and MPLS the work includes:

• High Throughput
• TCP Stack Performance
• Disk Sub-System Performance
• Application Performance
• SC2003 BandWidth Challenge and Demonstrations

• DataTAG

• High Performance High Throughput
• TCP Stack Performance
• 10 Gigabit Ethernet
• SC2003 BandWidth Challenge and Demonstrations

• DataGrid WP7

• Performance, Throughput and QoS tests on GEANT
• Demo to EU 2003
• Monitoring

• Network Committees

ICFA SCSI

• SCI

SCI [Scalable Coherent Interface (ANSI-IEEE Std 1596-1992)]. From 1992 to 1998 the Manchester HEP group designed and built several interfaces to test the SCI memory-memory interconnect for use in the Level2 Trigger of the ATLAS experiment. SCI was extensively tested at CERN in the ATLAS Demo_B project during 1997 and 1998.
