....subcubes or submeshes. Moreover, some systems allow users working in different partitions to use different operating systems. This is a useful feature for system development: new and experimental versions can be tested in one partition, while users continue to use a stable older version in others [52, 151, 350]. It may even be possible to reboot a partition without any effect on jobs running in other partitions [129] Conversely, in non partitioned machines, one job may degrade the performance of another. Probably the most infamous example is found in machines like the NYU Ultracomputer and the IBM ....

....attributes are used to drive policy decisions. This feature serves two useful purposes. First, dynamic user level policy selection makes policy comparison a far simpler task. It is a key feature in making the DUnX kernel a conducive environment for experimental evaluation of policy alternatives [31]. A single shell script can create a cluster in which to run a suite of tests, and then run an application several times, changing the memory management strategies used each time. No system rebooting is required, and other users of the machine are unaffected (as far as policy is concerned) by the ....

.... Ramanathan and Ni conducted a study of critical factors in NUMA memory management reported in [25] We have also investigated OS level NUMA memory management through experimentation, both with the USMR programming library for the BBN GP1000 and with our DUnX kernel for the BBN GP1000 and TC2000 [14, 15, 17, 18, 19, 20, 21]. The unique contribution of this current work in relation to previous research is the complementary use of 1) measurements based on a flexible parameterized policy implementation that can explore a wide range of policy behavior and 2) an experimentally validated analytic model. Our focus has been ....

.... of architectural features on the performance of four migration and replication policies in [6] We have also investigated OS level NUMA memory management through experimentation, both with the USMR programming library for the BBN GP1000 and with our DUnX kernel for the BBN GP1000 and TC2000 [9, 10, 11, 12, 13, 14, 15, 18]. For this research, implementation based experimentation has several advantages over more formal approaches. Most importantly, real applications can be used as the workload. Additionally, the likelihood of discovering the subtle issues that may be important to addressing the problem increases. On ....
