Abstract

The computing and modeling environment of IIASA was studied in the context of computation-intensive ad resource-demanding applications/models which are being developed and used by the researchers/scientists of IIASA. High Performance Computing applicatins can be classified into two broad computing fields; sequential distributed and parallel distributed applications and these applications has been developed for heterogeneous operating system architectures such as Linux, Windows and Solaris etc. Majority of IIASA applications/models belong to the latter class of computing and these applications are resource demanding when the extensive and repetitive use of these applications is required according to the need of some research study. Not every sequential application can be easily parallelized; therefore, instead of re-programming sequental applications into parallel ones, the idea of distributing such applications on computing cluster/grid is often an effective approach for accelerating the work. In the light of available computing resources and modest modeling environment of IIASA, the virtualization and Sun Grid Engine (batch job scheduler and manager for cluster/grid) was efficiently exploited and designed, built and tested. This resulted in a computational cluster supporting multiple operating systems and multiple sequential distributed and parallel distributed applications/models along with multiple job execution types such as binaries and JAVA.
