high-bandwidth Infiniband (IB) networking throughout the cluster. This
 
is expected to result in several significant benefits for users
 
including: better I/O performance for all jobs, better job performance
 
for any multi-node ethernet jobs (they can now make use of IB) and, for
 
IB users, improved queue throughput (there are now 4x as many IB nodes)
 
as well as the ability to run larger IB jobs.

NOTE: The temporary mpirun settings that were recommended are no longer in effect, as all MPI traffic is now going over InfiniBand.

System Status

System status can now be found at docs.scinet.utoronto.ca


Mon 23 Apr 2018 GPC-compute is decommissioned, GPC-storage available until 30 May 2018

Thu 18 Apr 2018 Niagara system will undergo an upgrade to its Infiniband network between 9am and 12pm, should be transparent to users, however there is a chance of network interruption.

Fri 13 Apr 2018 HPSS system will be down for a few hours on Mon, Apr/16, 9AM, for hardware upgrades, in preparation for the eventual move to the Niagara side.

Tue 10 Apr 2018 Niagara is open to users.

Wed 4 Apr 2018 We are very close to the production launch of Niagara, the new system installed at SciNet. While the RAC allocation year officially starts today, April 4/18, the Niagara system is still undergoing some final tuning and software updates, so the plan is to officially open it to users on next week.

All active GPC users will have their accounts, $HOME, and $PROJECT, transferred to the new Niagara system. Those of you who are new to SciNet, but got RAC allocations on Niagara, will have your accounts created and ready for you to login.

We are planning an extended Intro to SciNet/Niagara session, available in person at our office, and webcast on Vidyo and possibly other means, on Wednesday April 11 at noon EST.
