Important Changes to the Unix Interactive Cluster

The Unix interactive cluster (its.caltech.edu) will soon be retired. These long-running Solaris systems will be replaced by new Linux systems, which will run concurrently for a brief transition period. Starting May 2, 2016, IMSS will make changes to users' dot files to minimize compatibility issues with the new Linux systems. Changes will be completed over a period of approximately one week and are detailed at http://imss.caltech.edu/content/unix-cluster-transition

For questions about this transition or assistance with modifying your dot files, please contact the Help Desk (x3500, help@caltech.eduhttps://help.caltech.edu.)

Don't let ransomware disrupt or destroy your work

Ransomware is a category of malicious software that is becoming increasingly widespread.  It differs from other kinds of malicious software in that its primary purpose is to render the victim's data files unusable (typically by encrypting them) until a "ransom" in difficult-to-trace virtual currency such as Bitcoin is paid. Organizations all over the world, including hospitals, police departments, and universities, have fallen victim to ransomware attacks. Affected systems to date have included Windows workstations and servers, Macs, linux workstations and servers, unpatched wiki or blog software, Android phones, and any data volumes these devices are able to access (e.g., external hard drives, network drives or file servers).

For advice on how to protect yourself from ransomware, please visit http://imss.caltech.edu.

Hoverboard Guidelines

Caltech prohibits the use, possession and storage of hoverboards, hands-free segways, and self-balancing scooters (collectively "hoverboards") on campus and in campus-owned or controlled buildings.    

When safety standards can be developed and implemented by the manufacturers, this prohibition will be revisited.

Amazon Web Services event on April 13th

Save the date for an Amazon Web Services (AWS) event on Wednesday, April 13th from 9:30AM to 11:30 AM in Beckman Institute Auditorium. IMSS will be hosting representatives from AWS to speak about how to cost effectively add more compute resources. RSVP HERE

AWS SPOT: Cost Effectively Add More Compute Resources 

With Amazon Web Services (AWS), you can spin up EC2 compute capacity on demand with no upfront commitments. You can do this even more cost effectively by using Amazon EC2 Spot Instances to bid on spare Amazon EC2 computing capacity. This allows users to get 90% off on demand prices (often as little as 1c per core hour) and has helped them run very large scale workloads cost effectively. For example, at USC a computational chemist spun up 156,000 core in three days. Also, with the recent release of the Spot fleet API, a researcher or scientist can easily have access to some of the most cost effective compute capacity at a very large scale. Learn how to effectively use these tools for your research needs.

When: April 13, 9:30-11:30am.  (Option to schedule office hours afterwards to discuss your particular workload.)
Where: Beckman Institute Auditorium
 
Speaking:
John Lilley, IMSS Lead System Administrator, will talk about how he uses the Spot market for Caltech research workloads
Dmitry Pushkarev, CTO of EC2 Spot for AWS
Boyd McGeachie, EC2 Spot Business Development Manager
