Abstract:
---------
Parallel processing depends not only on finding and expressing parallelism
but also on parallelism management, which deals with processes and
computational resources. Parallelism management is a difficult task, in
particular in parallel systems based on clusters of workstations. We claim
in this seminar that a parallelism management system should be built based
on a distributed operating system. This management system, in order to
allow parallel programs to achieve high performance and transparency and be
easy to use, should provide services such as establishment of a virtual
machine, mapping processes to workstations by exploiting global scheduling,
process instantiation by providing group process migration and process
creation, computation coordination, group communication and distributed
shared memory. In order to substantiate the claim, the first version of an
operating system managing parallelism, called GENESIS,� is presented. 
The generic parallel programs following both the SPMD and MPMD 
computational models with user primitives invoking the services of this 
operating system are shown. A relevant behavior of the management 
system, as a reaction to invocation of these primitives (transparent to 
the programmer) is elaborated. The results of the performance study of some 
parallel applications managed by the GENESIS system are shown and 
discussed.
