No Scheduled Downtime:  Yellowstone, Geyser_Caldera, HPSS, GLADE

Wednesday, September 17, 2014

Starting September 24, the GPUs in the Caldera cluster will be upgraded from NVIDIA M2070Q to NVIDIA K20X accelerators over the following week. The Caldera nodes will be removed from service four at a time and returned to service with upgraded GPUs.

We expect that most users will not be affected by the mix of old and new GPUs during this period. Any user who needs to work with a homogeneous set of Caldera nodes or needs to know the GPU model on the nodes should contact cislhelp@ucar.edu, and we will provide the current GPU status on the cluster.

Compared to the M2070Q, the K20X adapters are based on NVIDIA's newer Kepler architecture and, with six times as many CUDA cores and 70% more memory bandwidth, offer substantially improved performance over the current Fermi-based cards.

CISL has scheduled an “Advanced Usage of Allinea Tools” class on Wednesday, Sept. 24, from 9 a.m. to 4 p.m. in the VisLab at the NCAR Mesa Lab in Boulder. The class will provide a quick review of Allinea DDT and MAP core features and then provide hands-on exercises using advanced and additional features and concepts that were not covered in the introductory course in August.  

A significant portion of the day will be dedicated to using DDT and MAP to review or find issues in participants’ own codes. Participants who have specific bug or performance issues will have an opportunity to share their display via overhead projector and work as a class to find resolutions.

If you have not worked with Allinea tools or did not attend the basic class in August, log in to Yellowstone and work through the self-guided tutorial materials in /glade/u/home/paisley/demo_package/ before attending the advanced class. Also see Running Allinea DDT, MAP and PR jobs to begin using the Allinea tools on Yellowstone.

Space is limited. Please register here to attend.
