Abstract: Corruption of program stacks is detected by using guard words placed in the program stacks. A called routine executing on a processor checks a guard word in a stack of a calling routine. The checking determines whether the guard word has an expected value. Based on determining the guard word has an unexpected value, an indication of corruption of the stack is provided. Some routines, however, may not support use of guard words. Thus, routines that are interlinked may have differing protection capabilities. A determination is made as to the differing protection capabilities, an indication of the same is provided, and the routines are executed without failing due to the differing protection capabilities.

The first type copy operation is used to copy data from the source storage to the target storage and copy data from the source copy storage to the target copy storage for the determined source and target copy relationships having the indicator set. A second type of copy operations is used for source and target relationships not having the indicator set.

Abstract: The present invention describes a new method for implementing highly available data-parallel-operations on a computational grid. This new method provides high availability after a server fails or the grid experiences a partial network failure. The present invention invokes the data parallel operation's method on selected objects stored in partitions within a highly available distributed cache. It thereby takes advantage of the use of highly available data partitions implemented by the distributed cache as a means for reliably tracking the progress of method invocations within a data parallel operation even after a server or network failure occurs. Using the cache's partitions as the basis for tracking enables the present invention's method to restart method invocations and thereby ensure completion of the data-parallel operation. It also uses a completion object within the cache to ensure that completion of the data parallel operation is detected and reported in a highly available manner.

Abstract: A flash memory control technology with high reliability. In a power recovery process, a microcontroller is configured to duplicate a last write page of a run-time write block of a flash memory and thereby generate a duplicated page in the run-time write block. The microcontroller is further configured use the mapping information accessed from the duplicated page in rebuilding a physical-to-logical address mapping table rather than the mapping information accessed from the last write page. The microcontroller is configured to maintain the physical-to-logical address mapping table on a random access memory for the run-time write block and is further configured to use the physical-to-logical address mapping table to update a logical-to-physical address mapping table maintained in the flash memory.
