Call for Presentations:
IXPUG welcomes submissions on innovative work from KNL users in academia, industry and government labs, describing original discoveries and experiences that will promote and prescribe efficient use of manycore and multicore systems. The authors of the best scored abstracts and draft presentations will be selected for a full 30 minute presentation; others may be offered an opportunity to present shorter Lightning Talks.


Submission Guidelines:
A short Extended Abstract and Draft Presentation should be submitted by Sunday, August 6th. The suggested organization of the extended abstract is: short abstract summarizing the work, benefits and accomplishments; an introduction with an objective; accomplishments (analysis, optimization, algorithm/software design, tool design, experience, new concepts, etc.) with results; and a summary. An abstract submission must be a PDF file, in a convenient text format; two or three pages should be sufficient. The Draft Presentation does not need to be complete by this date. It should reflect the overall intent of the presentation and contain placeholders for the remaining content to be completed by the Final Presentation.  Presentations describing application results and work on KNL-specific features (e.g. use of MCDRAM, multi-node messaging (MPI) performance and configurations, and new performance tools exploitation) will be prioritized. For presentation format, please use the IXPUG presentation template and you can submit your abstract to IXPUG EasyChair (not available until August).


Topics of interest are (but not limited to):

  • VectorizationSIMD operations and directives, data layout
  • MemoryDDR/MCDRAM partitioning, memory affinity,  prefetching, latency, streams, etc.
  • CommunicationMPI inter-/intra-node performance, scaling and tuning for Omni-Path/IB
  • IO: Local disk vs global (Lustre, etc.)
  • Thread and Process ManagementAffinity, resource sharing in SMTs (simultaneous multi-threading) and Tiles
  • System Management: Memory/Cluster Modes, Large Pages,  Node Stats, XPPSL, OpenHPC
  • Hybrid Computing: MPI Process/Thread Partitioning, On-node/Off-node Scaling
  • Programming ModelsOpenMP, TBB, Cilk, hStreams, MPI, --others
  • Algorithms and Methods: Application Scaling and Vectorizable Algorithms
  • Tools: Benchmarking, Profiling, Performance Analysis, Affinity
  • Visualization: Software Performance, Algorithms, Methods
  • Deep Learning: Application to speech, image, bioinformatics, natural language, ...
