MPI
What is MPI ?
Message Passing Interface
Interface, send a message or MPI, a standard system of sending messages by which a group of academic researchers and industrial design. This interface on a wide range of computers, parallel implementation.

The Standard MPI the structure and application of a few procedural Constitution defines that to make the program parallel to that of the Send Message are used, it can be used. This procedure for a large number of users are not to be used and in addition it is the nature of the standard this procedure makes the software written with these procedures, the library, portability, high on the platforms have different.

implements several of the MPI is that, many of which are thoroughly tested and are sure. Many of which are free and even some without restrictions and agreements are not to be used. Implementation of MPI for different languages, including Fortran language, C, C, Java, etc. is available. Two implementations known to include Open MPI and MPICH.

library standard, such as MPI and PVM industry, the development of software for parallel to the boom has been building software for parallel and scalable it possible to have made....
MPMD
What is MPMD ?
Multiple Programs, Multiple Data

SPMD
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....
MISD
What is MISD ?
Multiple Instruction, Single Data
In the cloud the iPhone, SD (MISD) means the recipe ., the law of the data, the only sort of cloud, parallel architecture computers is that most of the units operational, Operations, different, and, on a given do. The architecture of a pipeline to this type of assign. however, may be say that the data after the processing in each stage of the pipeline is different. Computers are fallible, that the instructions are to run continuously, and they can errors are discovered and determined. in behavioral therapy, to name, repeat, etc. may be included in this account type.

for this architecture example is a lot like a few recipes, a few or a few orders given, that the usual techniques in the cloud are parallel, etc. does not exist. In particular, the navigation and computational resources better than the iPhone, the SD would accept. However, an outstanding example of the cloud-share your SD computer, control the flight of the space shuttle.

Also, an array systolic, the archetype of The your SD. Linda null and Julia , etc. array, systolic as SMS, that, account have....

GLBP
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....
