CACR is pleased to announce an award of $479,100 from the National Science Foundation Office of Cyberinfrastructure for the Skyalert project. Skyalert is an event-driven system to understand and disseminate events that are created from real-time sensors, such as astronomical telescopes that repeatedly scan the sky for change. The number of these astronomical transient detections will grow enormously over the next few years, and rapid follow-up observation will be the key to discovery. This will come from big observatories, small college observatories, and amateur astronomers. Skyalert delivers events from the Catalina Real Time Survey and the NASA SWIFT and Fermi observatories, as well as a dozen other projects that detect astronomical transients. Examples of such transients include supernovae, cataclysmic variables, gamma-ray bursts, blazar eruption, planetary microlensing, and other exciting astrophysics.
Skyalert delivers events in real time via email, Twitter, instant message, and other protocols to observatories that can do rapid follow-up — some completely automatically with no human in the loop. Other event-driven actions can include fetching data to build a data portfolio, and running machine-learning algorithms and classification rules to make better automatic decisions. The intention is for automated systems to make real-time intelligent decisions. Skyalert uses an international standard, VOEvent, enabling participation in the global event infrastructure, exchanging events with other event brokers, such as NASA’s GCN.

Important Information for SHC Users
As of Sept 8, 2009, SHC has been transitioned to the new sw stack (RHEL+OpenIB). There are currently 115 core4 nodes and 65 core8 nodes, in production. For more information, please visit the SHC Getting Started / System Guide.

Important Information for SHC Users
Over the next couple of days, more backend nodes from shc-a will be transitioned to shc-[c,new]’s cluster of backend nodes, running the new software stack. By Sept 4, there will be just 24 shc-a backend nodes, all the rest of the compute nodes will be running the new software stack, seen from shc-[new,c].
- Please port your codes to the new software environment if you’ve not already done so!
- Please report any porting problems you’re having; we’ll help asap.
- Details on how to rebuild your code for the new SHC environment can be found here
- Your MPI based code must be rebuilt for the new and improved shc software stack.
Preventive Maintenance on Sept 8 from 0800 to 1400 will encompass testing the complete transition of SHC compute and head node resources to the upgraded software stack environment. The fully upgraded production SHC cluster configuration will be two head nodes (shc-[a,b]) and 1180 Opteron compute node cores (163 dual cpu/dual core + 66 dual cpu/quad core).
Questions or concerns about the upgrade? Just let us know.
