Eine Metacomputer-Architektur auf der Basis einer kooperativen Ressourcenverwaltung

The computer center software (CCS) developed by the Paderborn Center for Parallel Computing (PC"2) supplies the user by a resource description language with a virtual view of the equipment available at PC"2 providing thus a possible basis for the design of a metacomputer with combined descriptive and integrative level. Main architecture components of the CCS system are the quenemanager (QM), the portmanager (PM), machine managers (MM_s) and mastershells. PM and QM represent the administration instances, while MM_s, realized as privileged UNIX daemon process, form the interface to the parallel computers in the PC"2. Encryption in Kerberos is used for network authentication. The deadlock problem in distributed batch operation is solved by a wound-wait algorithm. The distributed computing environment allows for PVM and PAMACS application.
