Implementing LOGFLOW on a workstation cluster
Péter Kacsuk, Zs. Puskás, Z. Nemeth · 2002
LOGFLOW is a distributed Prolog implementation running on transputer networks, developed at KFKI-MSZKI. To improve the capabilities and the power of LOGFLOW the system is ported onto workstation-clusters under the name WS-LOGFLOW. The new platform requires modification in the architecture of the system, in token transportation and in work distribution. This paper presents the modified architecture of WS-LOGFLOW, the new token distribution scheme, some detail of the porting processes, intra-node shared-memory communication and inter-node PVM-based message-passing communication.
