Conventional register files spread porting resources uniformly across all registers. This paper proposes a method called Asymmetric Clustering using a Register Cache (ACRC). ACRC utilizes a fast register cache that concentrates valuable register file ports to the most active registers thereby reducing the total register file area and power consumption....
The coastal ocean may experience periods of fluctuating
along-shelf wind direction, causing shifts between
upwelling and downwelling conditions with responses that
are not symmetric. We seek to understand these asymmetries
and their implications on the Eulerian and Lagrangian flows.
We use a two-dimensional (variations across-shelf and with
depth; uniformity along-shelf)...
The Oregon Coastal Transition Zone (OCTZ) extends several hundred
kilometers offshore where shelf flows interact with the northern California Current. A
primitive-equation numerical ocean model is used to study the upwelling circulation in this
region from 1 May to 1 November 2001. This OCTZ model obtains initial and boundary
conditions...
Accurately estimating the vertical flux of material reaching the seafloor from the overlying surface waters is essential for the paleoceanographic reconstruction of a wide variety of oceanic processes. Two approaches are currently being used. One consists of estimating mass accumulation rates (MAR) between dated horizons as the product of linear...
