Abstract: Systems and methods are provided for practicing Relational Fitness abilities. A relational fitness development and fundraising tool includes a server having a processor and a memory, a storage system in communication with the processor and storing challenge activity information, and a collaboration, reporting, and payment application stored in the memory and including a graphical user interface (GUI) module and a rule module. The processor executes the GUI and rule modules to selectively operate the application in a daily challenge mode, a training mode, a tournament mode, and a fundraising mode, where all of the operational modes involve user athletes completing relational fitness challenge activities in exchange for points and/or for fundraising dollars on behalf of a beneficiary. Other embodiments are also disclosed.

Abstract: A method for flow control may include obtaining a number of added receive buffers based on adding receive buffers to a shared receive queue, obtaining initiators each including a protocol data unit (PDU) window size, obtaining a number of active initiators based on determining whether each of the initiators is associated with an active network session, calculating a credit using the number of added receive buffers and the number of active initiators, determining that an initiator is associated with an active network session, and adjusting the PDU window size of the initiator using the credit.

Abstract: An epicyclic cross piston engine having a four, six or more cylinders. It has individual pairs of pistons rigidly connected together by connecting rods. The pistons travel axially in their respective cylinders for a complete reciprocal cycle. The cylinders are oriented at ninety degrees to each other. Connecting the respective rods together are a pair of crankshafts and a drive link that is connected to an output shaft. A substantially 360 rotation of said output shaft is produced by the complete reciprocal travel of each of the pistons in their respective cylinders.

Abstract: An apparatus and system for constructing a vertical wall provides an overlapping arrangement secured by internally disposed rods.
