Abstract: An approach for regional firewall clustering for optimal state-sharing of different sites in a virtualized/networked (e.g., cloud) computing environment is provided. In a typical embodiment, each firewall in a given region is informed of its peer firewalls via a registration process with a centralized server. Each firewall opens up an Internet protocol (IP)-based communication channel to each of its peers in the region to share state table information. This allows for asymmetrical firewall flows through the network and allows routing protocols to ascertain the best path to a given destination without having to take firewall placement into consideration.

Abstract: A large area electrical contact for use in integrated circuits features a non-planar, sloped bottom profile. The sloped bottom profile provides a larger electrical contact area, thus reducing the contact resistance, while maintaining a small contact footprint. The sloped bottom profile can be formed by recessing an underlying layer, wherein the bottom profile can be crafted to have a V-shape, U-shape, crescent shape, or other profile shape that includes at least a substantially sloped portion in the vertical direction. In one embodiment, the underlying layer is an epitaxial fin of a FinFET. A method of fabricating the low-resistance electrical contact employs a thin etch stop liner for use as a hard mask. The etch stop liner, e.g., HfO2, prevents erosion of an adjacent gate structure during the formation of the contact.

Abstract: An expert system extracts events associated with executing an application from log files generated by various topological resources in a distributed computing environment. The events are plotted as plot points on a time series graph. Patterns are identified in the plot points that are associated with application problems, along with the computing environment configurations both before the problem and after the problem was resolved.

When a pattern repeats in conjunction with another application problem, the corrective action is identified as a possible solution to the new problem. A confidence level associated with the pattern/corrective action may be increased when a user accepts the corrective action and may be decreased when a user rejects the corrective action.
