program for enabling a parallel computer to use various tools
to transfer data among processors of the computer to effect a
rearrangement of address bits in the addresses of the data
stored in the processors’ memories. By way of example, one of
the tools is the “all-to-all personalized communication” tool
(AAPC) which is described in the Edelman reference. The AAPC
tool enables a
reassignment of data among storage locations of the various
processors to effect a rearrangement of address bits between
global and local bit locations.
Each processor includes a memory having a plurality
of storage locations, each location identified by a local
address having a particular encoding of a set of local address
bits. Each processor is identified by a global address having
an encoding of global address bits. Each storage location in
the parallel computer is identified by the combination of the
local and global address bits. For example, if there are “J”
address bits in bit locations a a the bits in bit locations
J-1… 0,
