System and method for queuing work within a virtualized scheduler based on in-unit accounting of in-unit entries
A system and corresponding method queue work within a virtualized scheduler based on in-unit accounting (IUA) of in-unit entries (IUEs). The system comprises an IUA resource and arbiter.

Thread switch for accesses to slow memory
A processing system suspends execution of a program thread based on an access latency required for a program thread to access memory. The processing system employs different memory modules having different memory technologies, located at different points in the processing system, and the like, or a combination thereof. The different memory modules therefore have different access latencies for memory transactions (e.g., memory reads and writes). When a program thread issues a memory transaction that results in an access to a memory module having a relatively long access latency (referred to as “slow” memory), the processor suspends execution of the program thread and releases processor resources used by the program thread. When the processor receives a response to the memory transaction from the memory module, the processor resumes execution of the suspended program thread. |

Providing services by using service insertion and service transport layers
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). |

Noise reduction in oscillator-based sensor circuits
A sensor circuit in a computer system measures a frequency of an oscillator circuit and uses the measured frequency to determine an operating condition of the computer system. The accuracy of the operating condition is limited by various sources of noise, including device noise, that introduce error into frequency measurements, limiting the accuracy to which the frequency of the oscillator signal may be measured. To improve the accuracy of the frequency measurement of the oscillator signal, the sensor circuit disables the oscillator between successive measurements, in order to reduce the correlation of error between the successive measurements. The sensor circuit combines the multiple measurement results to determine the frequency of the oscillator signal to a higher degree of accuracy, thereby improving the accuracy to which the operating condition is determined. |
