The
MIMD extracts the NTL from the beacon message and compare the present NTL ( ) value with the threshold NTL ( ) value.
MIMD computers support parallel solutions that require processors to operate in a largely autonomous manner.
As NPACI's leading-edge site, SDSC now has a 272-processor Cray T3E system (
MIMD, distributed memory) [9], a 128-processor IBM SP (
MIMD, distributed memory) [11], and a 14-processor Cray T90 (vector
MIMD, shared memory).
MIMD machines find particular use in applications such as image processing and finite element analysis of nonhomogeneous structures.
The IBM SP system is an
MIMD machine with distributed local memory (128Mb) attached to each of the 64 processors (P2SC, 120MHz).

7) Note that the SPMD data-parallelism model is opposed to the
MIMD (multiple program/data) activation/control-parallelism model.
The second experimental platform is a 64-processor Parsytec GCel [Langhammer 1992], an 8 x 8 mesh-connected
MIMD computer.
In the 1980s and 1990s, several general-purpose
MIMD computers were developed using microprocessors connected through a communication network or shared memory space.
Then, we developed a blocked version of the Level 3 BLAS for
MIMD vector multiprocessors [Amestoy and Dayde 1993; Dayde et al.
These alternatives are called distributed-memory
MIMD and shared-memory
MIMD, respectively and are illustrated in Figure 1.
The target machine is assumed to be a
MIMD architecture.
