Abstract: One or more computer processors receive a pattern string comprising a pointer to a pattern search point and a string comprising a pointer to a search point; determine a plausible search point within the string for the pattern character; execute a search string (SRST) instruction with the determined search point and the pattern character; compute a pattern offset comprising a difference between a first occurrence of the determined pattern character located within the pattern string but not in the correct position and a current pattern character position; execute a subsequent SRST instruction with the current pattern character position and the computed offset set as a new search point; and responsive to identifying all pattern characters in the correct position within the string based on the executed subsequent SRST instruction, transmit memory address associated with a substring comprised of the string and corresponding pattern characters in the correct position.

Abstract: Techniques are described for detecting anomalous behavior in program execution. In one example, a method includes logging occurrence of one or more key run time events during execution of a program. Each key run time event has a corresponding key run time event data structure associated with the program, and logging includes storing records associated with the key run time events, wherein each record is based on the key run time event data structure associated with the key run time event. The method further includes analyzing the records to determine if a current pattern of key run time events associated with the program during execution matches an expected pattern of key run time events and generating a security alert if the current pattern of key run time events does not match the expected pattern of key run time events for the program.

Abstract: Managing program function parameters using compiler directives is provided. A parameter management system can include a compiler coupled to a primary symbol-type dictionary and a supplemental symbol-type dictionary containing parameter data for specific function calls of corresponding generic type functions. Notably, directive processing logic can be configured both to populate the supplemental symbol-type dictionary based upon processor directives embedded in source code, and also to substitute specific function calls for generic function calls in the source code as specified in the supplemental symbol-type dictionary.

Abstract: A computer-implemented method including receiving a set of data having a mapping. The set of data has groups of subsets of data. The mapping describes in what order the groups of subsets of data are to be stored in a memory. The mapping also describes the offsets of the groups of subsets of data in the memory. The mapping is not changed when the set of data is stored in the memory. The method also includes determining a starting address for the set of data. The starting address corresponds to an address in the memory. The starting address is determined such that an optimum number of subsets of data in the groups of subsets of data are aligned. The method also includes storing the set of data in the memory, wherein the mapping is unaffected when the set of data is stored in the memory.

Abstract: A method for optimizing distributed memory access using a protected page. The method includes generating library calls to perform array accesses. The method further includes generating a layout map or assisting the accesses. Each processor possesses a local copy of this map. The method proceeds by allocating arrays across the processors, such that each processor receives a local portion of the array. The method further proceeds by reserving the memory location immediately before the local address. Then, the method proceeds by placing the memory location address under access protection, such that a protected page is formed.
