SUMMARY:MS40 - Abstraction, Orchestration and Modelling of Data Movement i
 n Heterogeneous Memory Systems
DESCRIPTION:Minisymposium\nComputer Science and Applied Mathematics\n\nArc
 hitecting and Programming Heterogeneous Memory Systems\n\nVetter, Peng\n\n
 Concerns about energy-efficiency and cost are forcing the US Exascale Comp
 uting Project to reexamine system architectures, and, specifically, the me
 mory and storage hierarchy. While memory and storage technologies have rem
 ained relatively stable for nearly two decades, new architectural features
 , su...\n\n---------------------\nAbstractions for Reasoning about Data Ob
 ject Movement\n\nHaine, Haus, Tate\n\nMoving data through memory has becom
 e a major performance bottleneck, with the bandwidth per FLOP decreasing a
 nd the complexity of the memory hierarchy quickly outgrowing software prog
 ramming environment abstractions. The Cray European Research Lab and our p
 artners are addressing this concern by des...\n\n---------------------\nUn
 derstanding and Optimizing Data-Movement in HPC Applications on Heterogene
 ous Memory Systems\n\nMarkidis, Olshevsky, Chien, Rivas-Gomez, Peng...\n\n
 Current top supercomputers feature a wide spectrum of diverse memory techn
 ologies, ranging from traditional DRAM to high bandwidth and on node non-v
 olatile memories. The diversity of memory technologies is expected to furt
 her increase in next generation supercomputers. These different memory tec
 hnol...\n\n---------------------\nECMWF's IO and Storage Challenges in the
  Path to Exascale Numerical Weather Prediction\n\nQuintino, Smart, Raoult\
 n\nStarting 2014, ECMWF has embarked on a 10 year research programme on HP
 C Scalability, aiming to achieve Exascale numerical weather prediction sys
 tems by 2025. ECMWF operational forecast generates massive amounts of I/O 
 in short bursts, accumulating to tens of TiB in hourly windows. From this 
 output,...\n
