Presented are embodiments of methods and systems for library-based compilation and dispatch to automatically spread computations of a program across heterogeneous cores in a processing system. The source program contains a parallel-programming keyword, such as mapreduce, from a high-level, library-oriented parallel programming language. The compiler inserts one or more calls for a generic function, associated with the parallel-programming keyword, into the compiled code. A runtime library provides a predicate-based library system that includes multiple hardware specific implementations (“variants”) of the generic function. A runtime dispatch engine dynamically selects the best-available (e.g., most specific) variant, from a bundle of hardware-specific variants, for a given input and machine configuration. That is, the dispatch engine may take into account run-time availability of processing elements, choose one of them, and then select for dispatch an appropriate variant to be executed on the selected processing element. Other embodiments are also described and claimed.

A single platform for the provision of multiple services over a cellular telephone network, comprises a generic definition of a cellular service, which is designed to take specific service-defining parameters, and a parameter setting mechanism for inputting respective service defining parameters to the generic definition, thereby to implement a desired service through the generic definition. The platform thus provides an infrastructure to support numerous services, and reduces the development time for individual services since they can be added as plug-ins to the platform using the generic definition which is shared.

The present application provides a method and device for solving the generic compatibility problem during hot update. The method transforms a runtime that only supports AOT static compilation into a runtime by adding an interpreter implemented by C++ to the IL2CPP tool. Support the runtime of AOT compiler and interpreter; at the same time, in order to solve the compatibility problem caused by the use of high-level language feature generics, the assembly including the original function metadata information is loaded into the IL2CPP runtime at the same time, which overcomes the need of the main program. The phenomenon that the function metadata information is lost after the code is compiled into machine code. When executing the new generic instance function in the hot update, point it to the execute function of the interpreter, and pass the MethodInfo structure of the original generic function to the execute function of the interpreter through parameters, thus completing the interpretation and execution of the function .

The invention discloses a geophysics inversion method based on a generic function reconstruction under a modified total variation model constraint. The method comprises the following steps: (1) constructing an inversion objective function aiming at the problem of regularized inversion of the modified total variation model constraint; (2) performing a generic function reconstruction on stable function terms of the modified total variation; (3) iteratively solving a calculation formula of a new model on the model itself according to an objective function minimization equation; and (4) setting inversion parameters, repeating the iteration to obtain a desired model result, and the result is used for inferring geological structures or positioning geological anomaly bodies. According to the geophysics inversion method based on the generic function reconstruction under the modified total variation model constraint, a generic function reconstruction method is innovatively provided, and the constraint property of the stable function term on the model is reserved, thereby greatly simplifying the numerical calculation difficulty caused by the high nonlinearity to the inversion; the inversionadopts a solution mode which is iterative to the model itself, and compared with a solution mode which is iterative to the correction amount of the model, the regularization directly applies a stablefunction constraint on the model, thereby obtaining a more reasonable model result.
