      The MIMD multiprocessor MP-X (various instruction threads over various data threads) consisting of 2^x- processing elements is a functional module designed for parallel computations.
      The MP-X rests on the following concepts;
      — combination of the MP-X multiprocessor with the general purpose host computer Y allowing to combine the advantages of parallel, vector and scalar, processing when executing a program that contains non-parallelizable fragments;
      — adaptibility of connectivity structure to the algorithms of the applications to be run (program emulation of various interprocessor connections);
      — design modularity which allows to upgrade the performance according to the user demands a;nd simplifies the transition to new microprocessors and new message passing technologies;
      — hardware support of the routing algorithms to increase the efficiency of the interprocessor transfers;
      — higher failure tolerance level of MP-X due to redundancy;
      — orientation to the common programming languages with the support of parallel program development tools standard in this field.
      The most efficient applications for MP-X-Y include: multidimensional problems in computational physics, design computerization, image processing, artificial intellect and others that require a maximum possible number of operations for this class of Y computers.
      The concepts presented are used in MP-0, MP-3 models and serve the base for MP-7 project.
      The description is given for the component base of existing and future models of some MP-X, as well as the software used for the development of parallel codes. The results are given for some test problems on various types of similar computers including MP-0 and MP-3.
      The report was accompanied by the illustrations arid demonstration of operational models.
