Abstract

Traditionally, the Local Area Network (LAN) has been used for parallel programming with PVM and MPI. The improvement of communications in Wireless Local Area Network (WLAN) achieving till 11 Mbps make them, according to some authors, candidates to be used as a resource for Grid Computing. Although CONDOR-MW tool can manage wireless communications using PVM (it is intended the use of MPI in future), in this paper we present a library based on LAM/MPI named LAMGAC in order to ease the programming of LAN-WLAN infrastructures. The novel of this research is that we can vary the parallel virtual machine in runtime, we generate algorithms in which computations and communications are efficiently overlapped and we include a web interface to offer our system as a Grid resource. At this moment we have measured the execution time of some algorithms and the functions of LAMGAC, obtaining interesting results.
