v21 v22 81 81 82 82 Based on the online monitoring information that have been gathered by the appropriate monitoring resources (WP1), diagnosed and classified in the Architecture Instant Map Database AIM-DB (WP2) a collection of strategies for improving the application mapping are considered. This self-adaptability scheme may, depending on the system policy, aim at: 83 [[BR]] 83 84 * Decreasing the system power consumption 84 85 * Ensuring real-time performance or more generally improving application performance … … 86 87 87 88 These strategies operate on a task basis as per defined by the application task graph. Only the following on-line operations are considered: 88 89 [[BR]] 89 90 * Migration. Tasks are moved from HW resource to HW resource for : 90 91 * Lowering communication cost / power consumption in order to improve performance if an alternative processing resource has a more appropriate support for a particular task. Additionally, if some of the processing resources have time-sliced execution capabilities (a CPU running a multitasking operating system); migrating tasks results in a higher performance since time is shared among fewer tasks. … … 94 95 95 96 * Router reconfiguration. For either communication performance (avoiding contentions) or for dealing with a hardware defect on some units/physical links, the routing tables may be changed at run-time. 96 97 [[BR]] 97 98 The two first classes of operations may take place in different ways: 98 99 * a fully centralized scenario where once the decision to remap the application has been taken, a global remapping is issued.
