Abstract: A virtual resources management method for a plurality of physical machines, includes: obtaining temperature values for the physical machines respectively; determining whether the temperature value exceeds a threshold value; categorizing the physical machines having temperature values exceeding the threshold value as an overheating group; selecting one of the physical machines as a candidate physical machine; determining whether the candidate physical machine belongs to the overheating group, wherein the virtual machine is assigned to the candidate physical machine when the candidate physical machine does not belong to the overheating group, and the virtual machine is assigned to one of the physical machines other than the candidate physical machine when the candidate physical machine belongs to the overheating group; and performing the virtual machine by the physical machine that is assigned the virtual machine.

Abstract: A method of optimizing multi-set context switch for embedded processors includes the steps of partitioning a plurality of registers into a plurality of register sets based on a live-range-sensitive context-switch procedure that is associated with a usage frequency of each of the registers, storing contents of first target registers according to live set information of a current task, wherein the first target registers are selected from the register sets, determining a next task by an operating system and updating the live set information according to the next task, and restoring contents of second target registers according to the updated live set information, wherein the second target registers are selected from the register sets.

Abstract: A method of streaming remote procedure invocation for multi-core systems to execute a transmitting thread and an aggregating thread of a multi-core system comprises the steps of: temporarily storing data to be transmitted; activating the aggregating thread if the amount of the temporarily stored data is equal to or greater than a threshold and the aggregating thread is at pause status; pausing the transmitting thread if there is no space to temporarily store the data to be transmitted; retrieving data to be aggregated; activating the transmitting thread if the amount of the data to be aggregated is less than a threshold and the transmitting thread is at pause status; and pausing the aggregating thread if there is no data to be retrieved.
