What is MPMD ?
Multiple Programs, Multiple Data
Multi-program multi-data (MPMD) in the science cloud is one of the techniques is to achieve computing parallel it used to be. This method, set method, several ordered multiple data (MIMD). In this method, split and in parallel on several processors with the input of parallel to achieve a faster result Run can be.

What is SPMD ?
Single Program, Multiple Data
A program multiple data (SPMD) in the science cloud is one of the techniques is to achieve computing parallel it used to be. This method, set method, several ordered multiple data (MIMD). In this method, split and in parallel on several processors with the input of parallel to achieve a faster result Run can be. Techniques SPMD the most commonly used method in parallel processing. This method is also the prerequisite concepts of research, such as messages, active memory and distributed shared.

techniques SPMD usually to method transfer messages the program in a computer architecture using memory distributed are applied, a computer architecture distributed from a number of independent computer composed that each one of them, node (Node) call. Each node program begins and through send and receive messages with other nodes to communicate. With the use of calling, send/receive. The possibility of implementation commands, such as the impossibility of sync (Barrier Synchronization), and also with messages there. This message, with methods of data transfer such as TCP/IP on Ethernet or proprietary methods very high speed such as Myrinet and domestic connections supercomputer implementation of. Section Serial program through the calculation of pointers is quite similar in all the nodes is implemented, and virtually of the methods such as calculating the result in one node and send the result to the other nodes don't use.

in a machine with memory shared etc. can be applied to a message, re-submit its contents in an address space shared access. This method is usually the most optimal procedures in the planning computers with address space shared and the number of processors is high. Especially in the car, NUMA is that memory belongs to any processor has access to memory of other processor needs more time. Techniques SPMD machines, the memory shared, usually by the process of Standard very heavy implement.

unlike SPMD, etc. with memory shared to which multi-processor parallel (SMP) is also applicable. to the programmer the possibility of using a memory space shared gives, in which process, in parallel on different processors, and separate routes run can be. Program in a processor starts and its implementation to the regions split can be that at the time of the start of the parallel instructions are implemented. In the areas of parallel and ... processor, a program with a different data run. An example. Loop Do .... Loop. in which different processors are busy implementing the different parts of the array within the loop are responsible for. At the end of the loop, the results of the sync are at this time only one processor is busy and other processors are in waiting mode. Interface the current standard for with shared memory OpenMP is called, and usually using a process of non- to the name of the yarn (threads) implementation.

computers, the current possibility of combining many rules and modes parallel to achieve the maximum amount of productivity to the programmer. A program distributed memory that MPI uses can be on a very large number of nodes run. each node can be a computer with memory shared and to be parallel in several processors by the OpenMP run. Within each processor, etc. recipes vector SIMD (usually automatically by the compiler are run) and instructions Superscalar (usually by the CPU for an independent run can be) such as Pipelining and the use of several units operating separate parallel to achieve maximum speed in each processor are used.

techniques SPMD first in 1983 by Michel Auguin and Francois Larbey in computer parallel OPSILA used and then in 1984 by Bride Darema at IBM for the machine, above parallel, such as RP3 was used. Based on one of the documentation, non-published IBM in the 1980's from non-standard lot for the transfer of the messages is remembered, but first, the standard SPMD, PVM has been. The dominant standard today, MPI.

the technique of parallelization of Cray the previous generation, OpenMP can be....

What is GLBP ?
Gateway Load Balancing Protocol
GLBP like (Hot Standby Router Protocol (HSRP and (Virtual Router Redundancy Protocol (VRRP traffic data against the disorder of the router or circuit, etc. protection) and let the share Packet between a group of routers Redundant.
before you do the settings GLBP, you must routers the desired direction of the applied settings examine up from a few MAC address on the Interface physical support. Note that in order to do the settings each GLBP Forwarder from a MAC address using the individual.

features GLBP
one of the features of GLBP is that for those file that have a Default Gateway on a network IEEE 802.3 configuration. router auto-backup, etc. to create. Multi-Hop, the first of the routers, etc. on the LAN are combined, a router, an IP hop, the first virtual formed and the time Forwarding the IP packet to share the truth. Other routers on the LAN might as routers Redundant for GLBP Act, and when each of the Forwarding Router available from the work of destruction. " active return.
performance GLBP for the user, similar to HSRP and VRRP. but the difference is that in the process of running with them. Protocol, HSRP, and VRRP to the multi-router, allow in the group Virtual Router, with an IP virtual configuration. company) and then one of the members as the Active Router, will be selected to Packet sent to the IP address of the virtual for the group submit a result in other routers group, until the router active, system routers Redundant are considered. Standby Router bandwidth of that protocol don't use it. Although multi-group Virtual Router can be used for a group of routers configuration. host must be for Gateway default types are configured in a way that result in more volume, management. GLBP uses a Virtual IP and multiple MAC virtual to dampen the load on a few routers (Gateway) pays. Any host with the same Virtual IP can be configured, and all routers group the Virtual Router, send out Packet participation. Members of the GLBP with the message, Hello that every 3 seconds for Multicast, to address 224,0,0,102, etc. protocol, UDP port 3222 (source and destination) is sent, communicate....
What is MANET ?
Mobile Ad hoc Network
An ad hoc Network animated (MANET) is a network without infrastructure, self configuration of the machine is animated that for wireless to connect. The term ad hoc is a Latin word, and the word that means IT \"application case\".

each device in a MANET to move in any direction, independence and complete freedom. that is why a lot of times, the connection between each device movable with the other of the devices frequently change. Also, each of which have traffic non-related to your forward transmit (forwarding), etc., so built also. The main challenge in building a MANET is that each device, any time, be equipped, which are alternately on. the information required to route traffic properly maintained. This is such a network (MANET) also may be with their work and may be connected to the internet.

MANET a type of ad hoc networks Wireless Ad hoc Network) that are usually on top of Link Layer ad hoc network, a perimeter network, reliable routing.
