extracts the NTL from the beacon message and compare the present NTL ( ) value with the threshold NTL ( ) value.
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) , a 128-processor IBM SP (MIMD
, distributed memory) , and a 14-processor Cray T90 (vector MIMD
, shared memory).
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).
Compiling Fortran D for MIMD
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
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
