A method and apparatus for providing efficient strong atomicity is herein described. Optimized strong operations may be inserted at non-transactional read accesses to provide efficient strong atomicity. A global transaction value is copied at a beginning of a non-transational function to a local transaction value; essentially creating a local timestamp of the global transaction value. At a non-transactional memory access within the function, a counter value or version value is compared to the LTV to see if a transaction has started updating memory locations, or specifically the memory location accessed. If memory locations have not been updated by a transaction, execution is accelerated by avoiding a full set of slowpath strong atomic operations to ensure validity of data accessed. In contrast, the slowpath operations may be executed to resolve contention between a transactional and non-transaction access contending for the same memory location.

A water recycling system for recycling water produced by a fuel cell module is provided. The water recycling system includes a fan, a mixing tank, and a duct. The fan has an exhaust opening and a suction opening adjacent to a cathode of the fuel cell module. The fan is used to vaporize water produced by the fuel cell module into vapor and exhaust the vapor from the exhaust opening. The mixing tank has a fuel inlet and a fuel outlet. A fuel for the fuel cell module is injected into the mixing tank via the fuel inlet, and the fuel outlet is connected to the fuel cell module. The duct has a first end and a second end. The first end is connected to the exhaust opening, and the second end is in contact with the fuel inside the mixing tank.

A method and apparatus for efficient and consistent validation/conflict detection in a Software Transactional Memory (STM) system is herein described. A version check barrier is inserted after a load to compare versions of loaded values before and after the load. In addition, a global timestamp (GTS) is utilized to track a latest committed transaction. Each transaction is associated with a local timestamp (LTS) initialized to the GTS value at the start of a transaction. As a transaction commits it updates the GTS to a new value and sets versions of modified locations to the new value. Pending transactions compare versions determined in read barriers to their LTS. If the version is greater than their LTS indicating another transaction has committed after the pending transaction started and initialized the LTS, then the pending transaction validates its read set to maintain efficient and consistent transactional execution.

Methods and an apparatus for forming a transaction object instruction construct are provided. An example method translates a source instruction construct to form a transactional objective instruction construct, executes the transactional objective instruction construct, intercepts an aborted transaction associated with the transactional objective instruction construct during execution, maintains a graph of nodes and edges associated with the executed transactional objective instruction construct to predict a deadlock situation, and resolves the deadlock situation associated with the transactional objective instruction construct based on the graph.

A method and apparatus for controlling multi-fluid flow in a micro channel is disclosed. The apparatus has a first inlet for a first fluid; a second inlet for a second fluid; a first outlet; and a second outlet. The micro channel is operatively and fluidically connected to the first inlet, the second inlet, the first outlet and the second outlet. The micro channel is for receiving the first fluid and the second fluid under pressure-driven flow; there being an interface between the first fluid and the second fluid when in the micro channel. The apparatus also includes a pair of electrodes for having a first electric field applied thereto for a controlling the fluid flow velocity of the first fluid along the micro channel.
