Abstract Interface) should be available on a parallel machine. This
is the aim of the presented architecture. The GFLOPS
The object of the GFLOPS project was to study all puter provides an elaborate shell munication
concerning the design of a low cost parallel architecture. The and synchronization logic to support global-memory
project's aim was to develop a parallel architecture as well as access, prefetch, atomic operations, barriers, and block
its software environment to implement image processing transfers [l]. Based on this design, a simple but powerful
applications efficiently. The proposed architecture supports up parallel extension to the C language has been designed
to 512 processor nodes, which are PC mother boards, with the goal of extracting the full performance capability
connected over a scaleable and cost-work, via the out of this machine. The basic approach is to provide a
PCI-bus, at a constant cost per node. The aim is to obtain at
low cost a scaleable virtually shared memory machine with a full C language on every node, with a rich set of
physically distributed architecture. In this paper we present the assignment operatio
