ABSTRACT

 

NEUCOMP2 is a parallel Neural Network Compiler for a shared-memory parallel machine. It compiles a program written as a list of mathematical specifications of Neural Network (NN) models and then translates it into a chosen target program which contains parallel codes. In this paper we present the performance results for intertwined spiral problem on popular NN models. The models are the Backpropagation, Kohonen, and Counter propagation models. NEUCOMP2 was developed on the Sequent 8000 computer system at PARC.

 

ABSTRAK

 

NEUCOMP2 adalah Pengkompilasi Rangkaian Neuron selari untuk mesin selari berkongsi-ingatan. Ia mengkompilasi atur cara yang ditulis dalam bentuk senarai spesifikasi matematik bagi model Rangkaian Neuron (RN) dan kemudian menterjemahkannya kepada atur cara sasaran yang dipilih mengandungi kod-kod selari. Dalam makalah ini dibentangkan keputusan prestasi penyelesaian masalah lingkaran berkembar menggunakan model­-model RN tertentu. Model-model ini adalah model rangkaian Perambatan Balik, Kohonen, dan Lawan Perambatan. EUCOMP2 dibangunkan pada sistem komputer Sequent 8000 di PARC.
