Quality of service scheduling with workload profiles
Examples described herein include systems and methods for prioritizing workloads, such as virtual machines, to enforce quality of service (“QoS”) requirements. An administrator can assign profiles to workloads, the profiles representing different QoS categories. The profiles can extend scheduling primitives that can determine how a distributed resource scheduler (“DRS”) acts on workloads during various workflows. The scheduling primitives can be used to prioritize workload placement, determine whether to migrate a workload during load balancing, and determine an action to take during host maintenance. The DRS can also use the profile to determine which resources at the host to allocate to the workload, distributing higher portions to workloads with higher QoS profiles. Further, the DRS can factor in the profiles in determining total workload demand, leading to more efficient scaling of the cluster. |

Dynamic load balancing of compute assets among different compute contexts
Examples are described here that can be used to allocate commands from multiple sources to performance by one or more segments of a processing device. For example, a processing device can be segmented into multiple portions and each portion is allocated to process commands from a particular source. In the event a single source provides commands, the entire processing device (all segments) can be allocated to process commands from the single source. When a second source provides commands, some segments can be allocated to perform commands from the first source and other segments can be allocated to perform commands from the second source. Accordingly, commands from multiple applications can be executed by a processing unit at the same time. |

Specifying service chains
Some embodiments provide novel methods for performing services for machines operating in one or more datacenters. For instance, for a group of related guest machines (e.g., a group of tenant machines), some embodiments define two different forwarding planes: (1) a guest forwarding plane and (2) a service forwarding plane. The guest forwarding plane connects to the machines in the group and performs L2 and/or L3 forwarding for these machines. The service forwarding plane (1) connects to the service nodes that perform services on data messages sent to and from these machines, and (2) forwards these data messages to the service nodes. In some embodiments, the guest machines do not connect directly with the service forwarding plane. For instance, in some embodiments, each forwarding plane connects to a machine or service node through a port that receives data messages from, or supplies data messages to, the machine or service node. In such embodiments, the service forwarding plane does not have a port that directly receives data messages from, or supplies data messages to, any guest machine. Instead, in some such embodiments, data associated with a guest machine is routed to a port proxy module executing on the same host computer, and this other module has a service plane port. This port proxy module in some embodiments indirectly can connect more than one guest machine on the same host to the service plane (i.e., can serve as the port proxy module for more than one guest machine on the same host). |

Wind aeolipile
Described herein is essentially a high-efficiency, hybrid fluid-aeolipile. In operation, this hybrid device is placed in the stream of a moving fluid, preferably air. Energy is extracted from the fluid stream by directing a portion of the stream through and, optionally, around the device. As the fluid-flow moves through the device, it is directed into nozzles. These nozzles, which are free to pivot in a cyclical manner, employ the established phenomenon of “nozzle-effect” to accelerate the velocity of the air-flow passing through them, which is ultimately ejected from each nozzle tip, producing thrust. This thrust, amplified by nozzle-effect, drives the nozzles to pivot around a shared axis. The wind energy, thereby converted into cyclical motion, that may be used to perform useful work, is converted with greater efficiency, than is possible in conventional blade-type wind turbines. |

Parallel functional testing of synthetic DNA parts, pathways, and genomes
The invention relates to a process for determining the functionality of an artificial genetic element. An artificial genetic element designed to serve the same biological function as a native genetic element is introduced into cells, and the cells are subjected to conditions of high frequency transposon mutagenesis. Subsequently, a set of DNA sequences representative of a site of insertion of the transposable element is obtained from the cells and the frequency of insertion of the transposable element into the native genetic element and the artificial genetic element is determined. Comparing the frequency of transposon insertion allows for assigning a likelihood of functionality to said artificial functional element, which is high if the frequency of transposon insertion is essentially equal for both elements, and which is low if the frequency of transposon insertion is higher into the artificial genetic element. |
