Derecho: Group Communication at the Speed of Light
نویسندگان
چکیده
Today’s platforms provide surprisingly little help to developers of high-performance scalable services. To address this, Derecho automates the creation of complex application structures in which each member plays a distinct role. Derecho’s data plane runs a novel RDMAbased multicast protocol that scales exceptionally well. The Derecho control plane introduces an asynchronous monotonic logic programming model, which is used to implement strong guarantees while providing a substantial performance improvement over today’s fastest multicast and Paxos platforms. A novel subgrouping feature allows any single group to be structured into a set of subgroups, or sharded in a regular pattern. These features yield a highly flexible and expressive new programming option for the cloud.

QED second order corrections on the speed of light at low temperature
We want to study thermal corrections on the speed of light at low temperature considering temperature dependence of photon vacuum polarization tensor at two-loop level in the standard QED. It is found that the heat bath behaves as a dispersive medium for the propagation of light and reduces its speed proportional to the second order of temperature. Similarities and differences, in light ...
متن کاملGroups, Subgroups and Auto-Sharding in Derecho: A Customizable RDMA Framework for Highly Available Cloud Services
Derecho is an RDMA-based distributed computing framework that unifies group membership management, consistent data replication and persistence. Applications are structured as top-level groups which can be split into subgroups or automatically sharded in a regular manner. To preserve membership invariants, Derecho adjusts subgroup membership as parent-group membership evolves. The resulting mix ...

Background: The formation of skin scars is inevitable following surgery, trauma and burns. Wound healing is a complex process that occurs during the competition of collagen production and collapse mechanisms. Various factors such as diabetes can interfere this process with multiple mechanisms. There are also ways to speed up the process of repair and prevent wound formation which is the use of...

The purpose of current study was to investigate the spatio-temporal gait parameters and knee varus angle during walking at different speeds in young with knee varus. 18 subjects with varus deformity classified at grade 3 of bowleg and 17 healthy subjects, volunteered to participate in this study. The following variables include stance, swing, double support and cycle time, cadence, stride le...
متن کاملA Study of the Wear Behavior of a Rail Material
The rail track is one of the most important elements of a railway system. During the passage of trains, the rails are subjected to contact load that comes from the wheels of the train. The railway track often fails in service due to wear caused by contact fatigue and other wear damage mechanisms that could also limit the life span of the railway infrastructure and railway vehicle. The aim of t...
