The squeue command will report "ReqNodeNotAvailable" ("Required Node Not Available"). The showq utility will list the job as "BLOCKED" and report its status as "WaitNod" ("Waiting for Nodes"). Note that the hours leading up to the maintenance are an excellent time to submit shorter, smaller jobs that can complete before the maintenance begins: as the queues drain there will be many nodes available, and your wait time may be short.

We will be taking an exceptionally long, one time only maintenance period on Lonestar5 from Sunday, October 14 through Saturday, October 20, 2018. Many of you have likely noticed “old” components in the software stack for Lonestar; unfortunately at this point our only option to update involves essentially reinstalling parts of the core OS from scratch – and the unique nature of the Cray makes this exceptionally time-consuming. 

Please communicate, by submitting a ticket, any major concerns and we'll attempt to find alternative accommodations on other systems if necessary.  Once again, we apologize for this multi-day disruption, and we hope (and have spent the last year working with Cray to ensure) that this is an extraordinary one-time event.

C++ can be considered as a superset of C, but this view often leads to un-idiomatic C++ programming. In this short course, we both show the new mechanisms of C++, and we explain what C mechanisms, while available, should no longer be used.

The first half of this course covers mostly object-oriented programming and parameter passing with references; the second half covers advanced topics such as smart pointers, exceptions, iterators, lambdas, templates.

This course will be offered to in-person and webcast attendees. Local participants are strongly encouraged to attend in-person. Students are expected to be familiar with C syntax and should bring a laptop for lab exercises.
