What Every Programmer Should Know About Memory

As CPU cores become both faster and more numerous, the limiting factor for most programs is now, and will be for some time, memory access. Hardware designers have come up with ever more sophisticated memory handling and acceleration techniques–such as CPU caches–but these cannot work optimally without some help from the programmer. Unfortunately, neither the structure nor the cost of using the memory subsystem of a computer or the caches on CPUs is well understood by most programmers. This paper explains the structure of memory subsys- tems in use on modern commodity hardware, illustrating why CPU caches were developed, how they work, and what programs should do to achieve optimal performance by utilizing them.

Deutsche Bank Research: India's specialisation in IT exports

This is surprising because exports of IT services are typically the premise of rich and technology-savvy countries. An educated workforce – which is abundant in rich countries but scarce in poor countries such as India – is the key resource. India’s export specialisation in skill-intensive products will be greatest by the year 2010 and regain this level only when GDP per capita will have reached USD 20,00
