Methods for measuring atrophy in a brain region occupied by the hippocampus and entorhinal cortex. In one example, MRI scans and a computational formula are used to measure the medial-temporal lobe region of the brain over a time interval. This region contains the hippocampus and the entorhinal cortex, structures allied with learning and memory. Each year this region of the brain shrank in people who developed memory problems up to six years after their first MRI scan. The method is also applicable for measuring the progression rate of atrophy in the region in an instance where the onset of Alzheimer's disease has already been established.

Techniques are described for optimizing memory management in a processor system. The techniques may be implemented on processors that include on-chip performance monitoring and on systems where an external performance monitor is coupled to a processor. Processors that include a Performance Monitoring Unit (PMU) are examples. The PMU may store data on read and write cache misses, as well as data on translation lookaside buffer (TLB) misses. The data from the PMU is used to determine if any memory regions within a memory heap are delinquent memory regions, i.e., regions exhibiting high numbers of memory problems or stalls. If delinquent memory regions are found, the memory manager, such as a garbage collection routine, can efficiently optimize memory performance as well as the mutators performance by improving the layout of objects in the heap. In this way, memory management routines may be focused based on dynamic and real-time memory performance data.

A method and system for providing a binary instrumentation tool to detect memory problems in a runtime application executing on a computer system includes identifying one or more functions or statements in the runtime application. A plurality of compiler annotations defining essential functional characteristic data of each of the plurality of functions is generated by a compiler when compiling the user program from source code to an executable binary code. A program error detector is configured to provide a checker code based on guidelines provided by of the plurality of compiler annotations associated with the function. The program error detector generates a modified function code for the identified function by inserting the checker code into a function code for the corresponding function. A modified executable binary code for the runtime application is then generated by replacing the function code for the function with the corresponding modified function code. When the modified executable binary code is run, the checker code associated with the function invokes a checker. The invoked checker provides performance data analysis that allows identification of program errors including memory errors in the runtime application.
