SUMMARY:Best Practices for Performance, Portability and Inclusivity
DESCRIPTION:Minisymposium\n\nMarta Garcia-Gasulla (Barcelona Supercomputin
 g Center)\n\nApplication developers and scientists from different fields r
 elying on HPC struggle to prepare their codes to run efficiently, even on 
 current leadership computer systems. Some of the challenges they face are 
 well known (e.g., parallelization inefficiencies caused by synchronization
 s, load imbalance, or communication patterns). Other constraints/inefficie
 ncies arise from new computing paradigms (e.g., how to manage input/output
  when dealing with big data) and the heterogeneity of computing resources 
 (e.g., when/how to efficiently exploit an accelerator).\n\nWe will share p
 atterns frequently found in parallel codes that lead to performance or por
 tability loss and a set of recommendations and best practices to avoid the
 se practices.\n\nThe proposed best practices are oriented to improve the c
 odes' performance and maintain developer productivity and portability of t
 he codes. These will be crucial in the exascale race to cope with the incr
 easing complexity of applications and computer systems, deal with the vari
 ety of architectures and paradigms, and ultimately run efficiently in an e
 xascale supercomputer.\n\nDomain: Climate, Weather, and Earth Sciences, Ap
 plied Social Sciences and Humanities, Computational Methods and Applied Ma
 thematics\n\nSession Chair: Marie-Christine Sawley (ICES Foundation)
