Parallelism and multicore


The goal of modern processor chip design has changed from optimizing various speed/price/heat tradeoffs for applications to finding excuses for dumping more transistors into the device.  Heard an interesting talk from Krisztián Flautner of ARM at the ACISC conference and I have to admit that it's not entirely the fault…

Deterministic multithreading


An interesting paper appearing in ASPLOS proceedings provides a "deterministic" locking method Kendo enforces a deterministic interleaving of lock acquisitions and specially declared non-protected reads through a novel dynamically load-balanced deterministic scheduling algorithm. The algorithm tracks the progress of each thread using performance counters to construct a deterministic logical time…
