Measuring performance or balancing the budget.

Measuring performance or balancing the budget.

In this scheme a "new" NHS built from the skill and experience of the old one for major conditions and an independent health service for routine conditions would be entirely complementary to each other. Margaret Thatcher has the opportunity, ability, and courage to implement this sort of radical surgery before health care in Britain becomes an incurable lost cause, both for those delivering it ...

Balancing the Deglacial Global Carbon Budget: The Hydrate Factor

The discovery that methane from dissociation of gas-hydrates could be an important factor in the global carbon cycle resolves the major discrepancy in estimates of the increase of terrestrial biomass from the Last Glacial period to the present. Carbon isotope budgeting using the marine carbon isotopic record results in an estimate centered around 500 GtC; whereas palaeovegetation reconstruction...

To Distribute or Not to Distribute: The Question of Load Balancing for Performance or Energy

Heterogeneous systems are nowadays a common choice in the path to Exascale. Through the use of accelerators they offer outstanding energy efficiency. The programming of these devices employs the host-device model, which is suboptimal as CPU remains idle during kernel executions, but still consumes energy. Making the CPU contribute computing effort might improve the performance and energy consum...

Load Balancing: a Programmer's Approach or the Impact of Task-Length Parameters on the Load Balancing Performance of Parallel Programs

We consider the problem of dynamic load balancing in an n processor parallel system. The scheduling process of a parallel program is modeled by randomly throwing weighted balls into n holes. For a given program A, the ball weights (task lengths) are chosen according to a probability distribution D(A), for which we know only some of the following parameters: the expectation , variance 2 , maximu...
