eResearch @ UniSAResearch at UniSA uses eResearch infrastructure to facilitate regional, national and international multidisciplinary collaboration. This wiki space is designed to promote initiatives in eResearch at UniSA and encourage discussion on new developments and how they'll impact research locally, nationally and internationally. Information is also availble on the UniSA eResearch website. UniSA wiki now supports federated and directory groups. You can now set Permissions on your wiki space or individual pages based on groups that will be automatically updated when users login. Federated groups (such as flinders.edu.au-student, utas.edu.au-staff or qut.edu.au-faculty) will also be automatically populated with affiliation information. Corporate LDAP directory groups will be prefixed with unisa: so the "UniSA-Web Authors" group will be listed as "unisa:unisa-web authors". This will make it much easier to maintain access controls to your wiki space.
UniSA staff members can request a wiki space to get the collaboration rolling. The [Shibboleth] Infrastructure that UniSA is building to connect to the [Australian Access Federation] has been used to connect to Google Apps. This trial is to highlight the benefits of Federated Authentication. The following services are currently available:

UniSA wiki is now live! The launch of the wiki is thanks to the effort of eResearch Group members of ISTS Systems Infrastructure team.
NIGHTCAP & Condor Compute PoolsWhat is NIGHTCAP?NIGHTCAP stands for No Infrastructure Green High Throughput Computing Application Pool. What is High Throughput Computing?High Throughput Computing or HTC is used to describe using many compute resources accomplish a computational task. This is different from High Performance Computing (or HPC) which provide specificly large memory or efficient CPU resources to complete a single compute task quickly. What is Condor?Condor is a high-throughput computing software framework for distributed parallelization of computationally intensive tasks. It can be used to manage workloads on a dedicated cluster of computers or farm out work to idle desktop computers. How is it green?This is a graph of the utilisation of a typical condor pool.
This "blue" can be thought of as the wastage of computing and power resources, as the computer is neither being used by a staff, students or HTC applications. Earlier versions of Condor required computer labs to be left running overnight to allow for compute jobs to complete. Condor 7.2 now provides power management features allowing a computer to enter a low power state (or turn off entirely) if it has been idle for a period of time. This feature is a core component in making NIGHTCAP a useful service and while achieving Universitiy's 2020 carbon reduction emission plan. When will the computers be turned off or powered down?Currently computers are powered down within 30 minutes of becoming idle outside of the operating hours of the computer pool or barn. So if a computer pool doesn't have access after 6pm a computer participating in NIGHTCAP will power down at 6.30pm if it isn't running any HTC task. The computer will be powered down 30 minutes after it has run its last HTC task. The exact timing will be adjusted throughout the project to balance the needs of student and HTC use of computer pools. Can you turn the computers back on?UniSA computer pools are automatically turned on at 7am each morning to apply any updates or patches to these systems in preparation for their use during the day. While this system hasn't been integrated into NIGHTCAP, work is underway to investigate this allowing additional compute resources to be "switched on" if needed. How many computers are in the Condor pool?Currently there are 25 computers in the NIGHTCAP Pool. It is anticipated that once we have completed the trial that we can expand this to over 1,000 computers throughout the University. What applications can be used?Condor can run the following applications:
Examples on how to run these applications will be provided shortly. More Information | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
