Foil 5 Latency Research Is Needed

From Summary of Working Groups at PAWS and PetaSoft Meetings PAWS(Mandalay Beach) and PetSoft(Bodega Bay) -- April 23 and June 17-19,96. by Geoffrey C. Fox


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