CHESS is an automated tool from Microsoft Research for finding errors in multithreaded software by systematic exploration of thread schedules. It finds errors, such as data-races, deadlocks, hangs, and data-corruption induced access violations, that are extremely hard to find with current testing tools. Once CHESS locates an error, it provides a fully repeatable execution of the [...]

“Why Apps Can’t Run Faster” explained that just putting more and more cores in chips doesn’t increase the processing speed of applications. This is because applications aren’t typically designed to take advantage of more than eight cores.
To be able to make the most of a multi-core processor, you can run lots of [...]

Roman Dementiev explains a simple technique he used for improving the scalability of his workload. His VTune™ analysis of the workload reveals that the top hot functions in the code were mmap, munmap and memset. However, his application does not use memory mapped files. The reason for existence of these functions is that the Linux [...]
