Technologies for tracking out-of-order network packets include a target computing node coupled to a source computing node via a communication channel. The target computing node is configured to allocate a small window in memory in which to store a bit mask corresponding to a number of out-of-order network packets received from the source computing node via the communication channel. The target computing node is further configured to update the bit mask in the small window upon receiving an out-of-order network packet from the source computing node. The target computing node is additionally configured to allocate a large window in memory in response to a determination the size of the bit mask is larger than the size of the small window, store the bit mask in the large window, and store a pointer to the large window in the small window. Other embodiments are described and claimed.

Technologies for tracking out-of-order network packets

In an embodiment, an out-of-order, reliable, end-to-end protocol is provided that can enable direct user-level data placement and atomic operations between nodes of a multi-node network. The protocol may be optimized for low-loss environments such as High Performance Computing (HPC) applications, and may enable loss detection and de-duplication of packets through the use of a robust window state manager at a target node. A multi-node network implementing the protocol may have increased system reliability, packet throughput, and increased tolerance for adaptively routed traffic, while still allowing atomic operations to be idempotently applied directly to a user memory location.

An ultrasound imaging system is provided which produces gray scale images of the anatomy simultaneous with Doppler signal processing so as to provide a single real-time image that shows not only the vascular anatomy and surrounding tissue but also flow events in the vascular compartment. A phased linear array having near-continuous focus over the scanning field provides high resolution and very small Doppler sample volumes. The system tests incoming signals from throughout the scanning field for amplitude, phase and frequency so as to determine B-mode data, motion presence and direction, and echo source velocity.
