Pipelined parallelization of multi-dimensional loops with multiple data dependencies
A mechanism for folding all the data dependencies in a loop into a single, conservative dependence. This mechanism leads to one pair of synchronization primitives per loop. This mechanism does not require complicated, multi-stage compile time analysis. This mechanism considers only the data dependence information in the loop. The low synchronization cost balances the loss in parallelism due to the reduced overlap between iterations. Additionally, a novel scheme is presented to implement required synchronization to enforce data dependences in a DOACROSS loop. The synchronization is based on an iteration vector, which identifies a spatial position in the iteration space of the loop. Multiple iterations executing in parallel have their own iteration vector for synchronization where they update their position in the iteration space. As no sequential updates to the synchronization variable exist, this method exploits a greater degree of parallelism. |

Methods and apparatus for providing error correction to unwritten pages and for identifying unwritten pages in flash memory
Provided are methods for error correction coding (ECC) for flash memory pages which have been erased but have not been programmed. In one method, each ECC code word is bitwise inverted before being programmed into a page, and bitwise inverted again after being read back from the page before entering the decoder. Thus an unwritten page, whose bits are all ones when random errors are absent, appears to the decoder as all zeros, which form a valid code word(s) in linear block codes. In another method, in both page programming and page read, the parity section of each ECC code word is bitwise XORed with the complement of a parity calculated from a message whose bits are all ones. Thus an unwritten page appears to the decoder as a valid ECC code word(s) when random errors are absent. Further provided is an apparatus for determining after a page read whether or not the read page has been programmed by comparing the number of read code word symbols which do not have the default erased value and the maximum number of symbol errors correctable by the ECC. |

Packet mirroring between primary and secondary virtualized software images for improved system failover performance
Packet loss at a standby server during failover results when the primary fails. There is currently always some amount of packet traffic that is inbound to the primary that is lost during the failover interval. With existing solutions, this packet loss during failover is inevitable.

System and method for controlling resource revocation in a multi-guest computer system
At least one guest system, for example, a virtual machine, is connected to a host system, which includes a system resource such as system machine memory. Each guest system includes a guest operating system (OS). A resource requesting mechanism, preferably a driver, is installed within each guest OS and communicates with a resource scheduler included within the host system. If the host system needs any one the guest systems to relinquish some of the system resource it currently is allocated, then the resource scheduler instructs the driver within that guest system's OS to reserve more of the resource, using the guest OS's own, native resource allocation mechanisms. The driver thus frees this resource for use by the host, since the driver does not itself actually need the requested amount of the resource. The driver in each guest OS thus acts as a hollow “balloon” to “inflate” or “deflate,” that is, reserve more or less of the system resource via the corresponding guest OS. The resource scheduler, however, remains transparent to the guest systems. |

A method for high dynamic range compression uses a modified cumulative histogram as a compression curve. This curve is computed from the cumulative histogram of the image with constraints that the local derivative on the curve does not exceed a certain limit.
