SUMMARY:Introduction - 9th Workshop on Latest Advances in Scalable Algorit
 hms for Large-Scale Systems
DESCRIPTION:Vassil Alexandrov (Barcelona Supercomputing Center), Al Geist 
 (Oak Ridge National Laboratory), Jack Dongarra (University of Tennessee), 
 and Christian Engelmann (Oak Ridge National Laboratory)\n\nNovel scalable 
 scientific algorithms are needed in order to enable key science applicatio
 ns to exploit the computational power of large-scale systems. This is espe
 cially true for the current tier of leading petascale machines and the roa
 d to exascale computing as HPC systems continue to scale up in compute nod
 e and processor core count. These extreme-scale systems require novel scie
 ntific algorithms to hide network and memory latency, have very high compu
 tation/communication overlap, have minimal communication, and have no sync
 hronization points. With the advent of Big Data in the past few years the 
 need of such scalable mathematical methods and algorithms able to handle d
 ata and compute intensive applications at scale becomes even more importan
 t. \n\nScientific algorithms for multi-petaflop and exaflop systems also n
 eed to be fault tolerant and fault resilient, since the probability of fau
 lts increases with scale. Resilience at the system software and at the alg
 orithmic level is needed as a crosscutting effort. Finally, with the adven
 t of heterogeneous compute nodes that employ standard processors as well a
 s GPGPUs, scientific algorithms need to match these architectures to extra
 ct the most performance. This includes different system-specific levels of
  parallelism as well as co-scheduling of computation. Key science applicat
 ions require novel mathematics and mathematical models and system software
  that address the scalability and resilience challenges of current- and fu
 ture-generation extreme-scale HPC systems.\n\nTag: Algorithms, Heterogeneo
 us Systems, Resiliency\n\nRegistration Category: Workshop Reg Pass\n\nSess
