Next: 4.2.4 Machine model parallelism Up: 4.2 WRAPPER Previous: 4.2.2 Supporting hardware neutrality Contents 4.2.3 WRAPPER machine modelApplications using the WRAPPER are not written to target just one particular machine (for example an IBM SP2) or just one particular family or class of machines (for example Parallel Vector Processor Systems). Instead the WRAPPER provides applications with an abstract machine model. The machine model is very general, however, it can easily be specialized to fit, in a computationally efficient manner, any computer architecture currently available to the scientific computing community.
