Multi-lumen catheters with improved tip configurations, including a triple-lumen catheter which may be useful for apheresis. In one variation, the catheter has three lumens with distal openings angularly spaced apart and staggered axially with respect to one another. In another variation, the catheter has two lumens exiting distally and one centrally positioned lumen exiting proximally. A third variation is a catheter with a single distal opening and two proximal openings. The staggered lumen openings along the axial length of the catheter may decrease recirculation while maximizing flow rates.

A processor reduces wasted cycle time resulting from stalling and idling, and increases the proportion of execution time, by supporting and implementing both vertical multithreading and horizontal multithreading. Vertical multithreading permits overlapping or “hiding” of cache miss wait times. In vertical multithreading, multiple hardware threads share the same processor pipeline. A hardware thread is typically a process, a lightweight process, a native thread, or the like in an operating system that supports multithreading. Horizontal multithreading increases parallelism within the processor circuit structure, for example within a single integrated circuit die that makes up a single-chip processor. To further increase system parallelism in some processor embodiments, multiple processor cores are formed in a single die. Advances in on-chip multiprocessor horizontal threading are gained as processor core sizes are reduced through technological advancements.

Regular data packets are scheduled for transmission from a sender to multiple receivers in a multicast ARQ system. In a joint scheduling and encoding procedure, a composite data packet is formed as a weighted linear combination of regular data packets. The corresponding coding weights are adapted based on feedback information from the receivers about received data packets such the composite packet represents a new linearly independent coding of regular data packets different from any multicast data packet previously received each receiver in a selected set of the receivers during the multicast session. In addition, using a weight vector with at least two different non-zero coding weights adds a further degree of freedom and guarantees the ability to always form a composite data packet that represents a new linearly independent coding for transmission. The ability to transmit linearly independent data packets in at least a majority of the transmission instances will significantly improve the throughput performance for reliable multicasting, especially when the number of users is large.
