CMDV's C++/Kokkos rewrite of HOMME
by Robert Jacob 24 Apr '18

24 Apr '18

The C++/Kokkos rewrite of HOMME has been successful, at least by its performance measurements. Andy Salinger says: "I thought that several of you E3SM folks might be interested in the progress we have made on the “HOMMEXX” code, the C++/Kokkos rewrite of HOMME being done under CMDV-SM. The conversion is now “end-to-end”, meaning all the code within one physics time step is converted to C++ (although setup and I/O are not), so the timings are real and no longer just for certain converted kernels (as we showed at the ACME all-hands last June). Attached is a paper that we submitted last month to the Supercomputing Conference on the current performance portability of the HOMMEXX code where we show large-scale results for Edison, Cori-Haswell, and Cori-KNL (e.g. Fig 7), and small-scale results with the P100 Pascal GPU as well (Fig 9). Since that submission, we are now getting preliminary results on the Volta GPU and Skylake CPU processors." I'm told the caveat is: it took a hero programmer at Sandia to make it all perform well. If the same programmer had focused on just the Fortran with OpenACC, probably would have had just as good performance portability. The paper is available at https://anl.box.com/s/7fcndg637qd7hypuk8hyacr7xo9kx8or Rob

Youï¿½ve just reached a landmark occasion with this v1 release. THANK YOU so much for your hard work, especially during the past few months. This is an exciting time for all of us here at DOE, and I look forward to the great community research thatï¿½s now possible with E3SM.

Dear E3SM project team, Congratulations to all of you for reaching this major milestone of releasing E3SM v1! https://www.llnl.gov/news/new-exascale-system-earth-simulation We appreciate all the hard work and dedication that each of you has put into developing, debugging, optimizing, testing and managing this new model. It was a significant team effort in which many of you put aside your personal gains in order to contribute to the larger outcome. I am confident that the hard work will bear significant rewards as you may now use v1 for science investigations, publish results, and share the model with collaborators. I look forward to seeing this next stage unfold, as well as the enhancements to come in v2-v3-v4. All the best from us at DOE, Dorothy Biological and Environmental Research Department of Energy 301-903-0105

E3SM v1 release update
by Robert Jacob 06 Apr '18

06 Apr '18

Some facts related to the upcoming release of E3SM v1: E3SM v1 release is scheduled for April 20th. Along with the v1 release, E3SM will be launching a quarterly newsletter and new website (beginning April 23). Website will be e3sm.org. LLNL is doing the press release. I'll arrange a companion one from Argonne. E3SM's github repo will be made public and we'll continue to do all our development there. AFAIK, its the first major climate model to have a completely open repository. Rob
