Various technologies and techniques are disclosed for allowing a user mode stack to be shared by multiple contexts. A user mode stack can be shared between execution contexts that are guaranteed to not need the user mode stack at the same time. For example, each user mode portion of a kernel thread is provided with a dedicated backing thread. When a respective dedicated backing thread is sleeping and not using a respective user mode stack, the user mode stack is allowed to float with a respective user mode portion to other kernel threads. The user mode stack is disassociated from the kernel portion of the thread. The kernel is notified of an address of a user mode thread context. The kernel mode portion of the converted thread becomes a backing thread that waits. The user mode portion of the converted thread can be switched without entering the kernel.

Operating profiles for consumers of computing resources may be automatically determined based on an analysis of actual resource usage measurements and other operating metrics. Measurements may be taken while a consumer, such as a virtual machine instance, uses computing resources, such as those provided by a host. A profile may be dynamically determined based on those measurements. Profiles may be generalized such that groups of consumers with similar usage profiles are associated with a single profile. Assignment decisions may be made based on the profiles, and computing resources may be reallocated or oversubscribed if the profiles indicate that the consumers are unlikely to fully utilize the resources reserved for them. Oversubscribed resources may be monitored, and consumers may be transferred to different resource providers if contention for resources is too high.

The names of contacts are stored as characters. Each character may include one or more phonic codes that are encoded into the character. A smart filter decodes the character into its constituent sounds. An input string is received that includes phonic codes. An application matches the decoded constituent sounds with the specified phonetic codes from the input string in accordance with rules of the spoken language and character boundaries to determine a contact to display.

High-speed processing of packets to, and from, a virtualization environment can be provided while utilizing hardware-based segmentation offload and other such functionality. A hardware vendor such as a network interface card (NIC) manufacturer can enable the hardware to support open and proprietary stateless tunneling in conjunction with a protocol such as single root I/O virtualization (SR-IOV) in order to implement a virtualized overlay network. The hardware can utilize various rules, for example, that can be used by the NIC to perform certain actions, such as to encapsulate egress packets and decapsulate packets.

Various technologies and techniques are disclosed for detecting and handling blocking events. A user mode thread is assigned a dedicated backing thread. System calls are made on the dedicated backing thread. The kernel detects when a system call results in a blocking event. A core that the dedicated backing thread is currently running on is observed. An entry in a per process table that maps cores to a currently associated primary thread waiting to be woken is consulted. The currently associated primary thread for the core is woken with a special result code to indicate that it was woken due to the blocking system call. The primary thread is released back to the application. A user mode scheduler is notified of the blocking event so a core can continue to be utilized.

Various technologies and techniques are disclosed for switching user mode thread context. A user mode portion of a thread can be switched without entering a kernel by using execution context directly based on registers. Upon receiving a request to switch a user mode part of a thread to a new thread, user mode register contexts are switched, as well as a user mode thread block by changing an appropriate register to point at the user mode thread block of the new thread. Switching is available in environments using segment registers with offsets. Each user mode thread block in a process has a descriptor in a local descriptor table. When switching a user mode thread context to a new thread, a descriptor is located for a user mode thread block of the new thread. A shadow register is updated with a descriptor base address of the new thread.
