ATOP-Grid is an adaptive middleware which supports workload redis- tribution under varying resource allocation in both the space and time dimensions. In earlier work, we have already shown that time-shared execution of jobs, which splits the CPUs or cores per node between two jobs but shares the network, may provide a performance benefit vs. space sharing, which splits the nodes among the jobs. In this paper, we make a step towards providing a sounder foundation for time-sharing performance, investigating the time sharing behavior of jobs in more detail and looking into communication characteristics, memory access, and cache usage.
