SMP

(Symmetric MultiProcessing) A multiprocessing architecture in which multiple CPUs, residing in one cabinet, share the same memory. SMP systems provide scalability. As business increases, additional CPUs can be added to absorb the increased transaction volume.

SMP systems range from two to as many as 32 or more processors. However, if one CPU fails, the entire SMP system is down. Clusters of two or more SMP systems can be used to provide high availability (fault resilience). If one SMP system fails, the others continue to operate.

A Pool of Resources

One of the CPUs boots the system and loads the SMP operating system, which brings the other CPUs online. There is only one instance of the operating system and one instance of the application in memory. The operating system uses the CPUs as a pool of processing resources, all executing simultaneously, either processing data or in an idle loop waiting to do something.

Whatever Can Be Overlapped

SMP speeds up whatever processes can be overlapped. For example, in a desktop computer, it would speed up the running of multiple applications simultaneously. If an application is multithreaded, which allows for concurrent operations within the application itself, then SMP will improve the performance of that single application.

Sequent, Pyramid and Encore pioneered SMP on Unix platforms. SMP servers are also available from IBM, HP, NCR, Unisys and others. Many versions of Unix as well as Windows NT/2000, NetWare and OS/2 have been designed for or have been revamped for SMP. Contrast with MPP. See also NUMA.

SMP and MPP Processing

In SMP, CPUs are assigned to the next available task or thread that can run concurrently. In MPP operation, the problem is broken up into separate pieces, which are processed simultaneously.

Coverage usually provided for large businesses in four areas:

1. Section I (Property)— The building(s) and contents are covered against either any peril (all risks basis) or only perils listed in Section I. It is to the advantage of the business to have coverage written on an all risks basis. Endorsements can be added for sprinkler leakage, business interruption, extra expense, water damage, rental loss, valuable records and papers, mercantile robbery and safe burglary, mercantile open stock burglary, glass and fine arts, or these items can be covered separately.


2. Section II (Liability)— The insured is covered for actions or nonactions that result in liability exposure arising out of ownership, use, possession and/or maintenance of the covered locations and structures.
Also covered are the business’s activities conducted by the insured whether at or from the covered locations and structures.
Endorsements can be added to cover for medical payments, liability arising out of products and completed operations, and liability arising out of operation of a nonowned automobile. Additional endorsements can be added to this section to broaden liability coverage.


3. Section III (Crime)— Coverage for employee dishonesty, premises loss both inside and outside of the structure, forgery by depositions, paper currency that proves to be counterfeit, and money orders.
The comprehensive dishonesty, disappearance, and destruction policy (3 - d policy) and the blanket crime policy provide these coverages.


4. Section IV (Boiler and Machinery)— Coverage for explosion of a boiler, engine, turbines, and/or pipes owned or under the control of the insured. Endorsements can be added to cover indirect and consequential losses resulting from accidents associated with the boiler and machinery expenses. The SMP has generally been replaced by the commercial package policy .
