An outcome is that a group will write a white paper; Mike Heroux is > leading the whitepaper group, and Sven is the Argonne rep on the writing team. > > I briefly spoke w. Rajeev Thakur and Rob Ross about the utility of increased > dialogue among Radix and LANS folks in general -- they indicated interest in > this. I know that some discussions are already happening. > > Another observation is that some other labs have pots of funding available > for incubating projects that can then be poised to compete strongly in > various FOAs. I wonder whether ANL has ever considered increasing the pool > of money available for LDRD projects that serve this purpose + provide more > opportunities for junior researchers to get experience in writing proposals. > > All for now -- > Lois > > P.S. - I plan to be at the lab on Nov 3 and 4. > > - - - - - - - > > Below are brief/incomplete notes from the final presentation of the workshop > by Bill Harrod (ASCR) and Thuc Hoang (NNSA): > > Challenges to achieving exascale computing: see prior presentation > > Real challenges to achieving success: see prior presentation > - avoid mediocre solutions, etc ... > > How will we succeed: > - formulating dynamic plan, executing plan > - focus on enabling HPC community to achieve extreme scale computing to > enable extreme-scale scientific discovery > - recognize what we do best and do it > - accept change > - open competition within DOE community for FOAs > - enable open discussions on exascale within DOE community > - enable an open collaborative environment > > What's next: > - Complete exascale plan: needs to be done by Nov 10 > - Release ASCR/X-Stack solicitation: expected in November > - runtimes, prog models, languages, compilers, and tools > - formulate the software stack plan > - workshop for extreme-scale algorithms > - electrical vs. optical interconnect workshop > - release ASCR/Extreme scale algorithms FOA > - more workshops, more FOAs > - subject to available funding > - start funding software technology, path forward and system design > programs > - April 16-19, 2012: Exascale research meeting and roadmapping workshop > (might expand to include April 20) > -------------- next part -------------- An HTML attachment was scrubbed...
