Caltech’s Summer Undergraduate Research Fellowships (SURF) program introduces students to research under the guidance of seasoned research mentors at Caltech and JPL. Students experience the process of research as a creative intellectual activity.
The PSAAP Project has posted an announcement of opportunity on the SURF website. There are opportunities for students interested in: i) Modeling and simulation of the dynamic behavior of materials under extreme conditions; ii) Experimental science in the broad areas of materials behavior and hypervelocity impact; iii) High-performance computing with emphasis on scientific petascale computing; and iv) Uncertainty quantification and rigorous certification of complex systems. Students applying should be pursuing a degree in engineering or science, possess a strong interest in one of the five center areas, and have excellent programming skills for computationally related areas.

Astronomy Tea Talk(s)
Tuesday, Dec. 16th, 2008
Rm 106 ROBINSON
10 AM
Raffaele D’Abrusco
(Dept. of Physics, Univ. of Naples)
“A data mining approach to selection and photometric redshift estimation of candidate quasars”
The talk will describe a data mining approach to the problems of the selection of candidate quasars from the photometric data produced by astronomical surveys and the estimation of photometric redshifts for the candidate QSOs extracted. Some details of the algorithms employed as well as the results of their application to SDSS and near infrared data will also be presented.

Second International Workshop on Practical Semantic Astronomy
2-5 March 2009
Glasgow, UK.
Semantic astronomy promises to expand the scientific discovery potential of exponentially growing data collections by enabling natural language querying, content-based searching, rich metadata markup and retrieval, rapid integration of diverse data collections, and machine-assisted scientific discovery.
Practical Semantic Astronomy 2009 is the second in a series of workshops first held at Caltech in February 2008. The workshop brings together experts from a broad range of disciplines using semantic technologies, alongside practitioners experimenting with these techniques to address current problems in astroinformatics.

Building on seven years of record-breaking developments, an international team of physicists, computer scientists, and network engineers led by the California Institute of Technology (Caltech)–with partners from Michigan, Florida, Tennessee, Fermilab, Brookhaven, CERN, Brazil, Pakistan, Korea, and Estonia–set new records for sustained data transfer among storage systems during the SuperComputing 2008 (SC08) conference recently held in Austin, Texas.
Caltech’s exhibit at SC08 by the CACR and the High Energy Physics (HEP) group demonstrated new applications and systems for globally distributed data analysis for the Large Hadron Collider (LHC) at CERN, along with Caltech global monitoring system MonALISA and its collaboration system EVO (Enabling Virtual Organizations), together with near real-time simulations of earthquakes in the Southern California region, experiences in time-domain astronomy with VOEventNet and Google Sky, and recent results in multiphysics multiscale modeling with the PSAAP project.
A highlight of the exhibit was the HEP team record-breaking demonstration of storage-to-storage data transfers over wide area networks from a single rack of servers on the exhibit floor. The team’s demonstration of “High Speed LHC Data Gathering, Distribution and Analysis Using Next Generation Networks” achieved a bidirectional peak throughput of 114 gigabits per second (Gbps) and a sustained data flow of more than 110 Gbps among clusters of servers on the show floor and at Caltech, Michigan, CERN (Geneva), Fermilab (Batavia), Brazil (Rio de Janiero, Sao Paulo), Korea (Daegu), Estonia, and locations in the US LHCNet network in Chicago, New York, Geneva, and Amsterdam.
The image shows a sample of the results obtained at the Caltech booth, monitored by MonALISA, flowing in and out of the servers at the booth. The feature in the middle of the graph is the result of briefly losing the local session at SC08 driving some of the flows.
