Foil 26 Latency Research Is Needed

From HPCC Futures Topic 2:A Possible PetaFlop Initiative Trip to China -- July 12-28,96. by Geoffrey Fox, Peter Kogge * See also color IMAGE

Latency tolerant algorithms will be essential
  • Today the most extreme latency issues are seen in networks of workstations and other such metacomputers.
Hardware mechanisms for hiding and/or tolerating latency.
Language facilities (such as programmer-directed prefetching) for managing latency.
Need a "hierarchy little language" to describe latency structure
Software tools, such as visualization facilities, for measuring and managing latency.
Performance studies of distributed SMPs to study latency issues.
