DESCRIPTION:Numerical simulations conducted on current high-performance com
 puting (HPC) systems face an ever growing need for scalability. Larger HPC
  platforms provide opportunities to push the limitations on size and prope
 rties of what can be accurately simulated. Therefore\, it is needed to pro
 cess larger data sets\, be it reading input data or writing results. Seria
 l approaches on handling I/O in a parallel application will dominate the p
 erformance on massively parallel systems\, leaving a lot of computing reso
 urces idle during those serial application phases.\n\nIn addition to the n
 eed for parallel I/O\, input and output data is often processed on differe
 nt platforms. Heterogeneity of platforms can impose a high level of mainte
 nance\, when different data representations are needed. Portable\, selfdes
 cribing data formats such as HDF5 and netCDF are examples of already widel
 y used data formats within certain communities.\n\nThis course will start 
 with an introduction to the basics of I/O\, including basic I/O-relevant t
 erms\, an overview over parallel file systems with a focus on GPFS\, and t
 he HPC hardware available at JSC. Different I/O strategies will be present
 ed. The course will introduce the use of the HDF5\, the NetCDF (NetCDF4 an
 d PnetCDF) and the SIONlib library interfaces as well as MPI-I/O. Optimiza
 tion potential and best practices are discussed.\n\nPrerequisites: Experie
 nce in parallel programming with MPI\, and either C/C++ or Fortran in part
 icular.\n\nApplication \nRegistrations are only considered until 1 March 2
 018 due to available space\, the maximal number of participants is limited
 . Applicants will be notified\, whether they are accepted for participitat
 ion.\n\nInstructors: Sebastian Lührs\, Dr. Michael Stephan\, Benedikt Ste
 inbusch\, Dr. Kay Thust\, JSC\n\nContact \nFor any questions concerning th
 e course please send an e-mail to s.luehrs@fz-juelich.de.\n\nhttps://event
