Our research is focused on keeping both local and parallel
jobs together in a non-dedicated cluster and scheduling
them efficiently. In such a system, memory becomes
a critical resource for both kinds of job. Thus, the minimization
of the impact caused by the overflow of physical
into virtual memory on the performance of distributed
jobs together with the development of an efficient memory
management adapted to the needs of NOWs (Networks
of Workstations) are major issues in this kind of
environment. An algorithm is presented to adjust time
slices dynamically to the necessities of distributed and
local tasks in order to reduce the number of page faults
across the cluster. Additionally, a memory management
policy aimed at preserving enough memory for both workloads
is evaluated. Our proposals are implemented in a
Linux cluster and compared with alternative algorithms.
