What kind of projects (besides the obvious OS stuff) use assembly language?

Question

Seemingly, no one uses assembly nowadays other than to develop device drivers, or the very core of OS kernels etc. Anyone has knowledge of it being currently used for other thin

Answer 1

More or less obviously, assembly programming is needed for compiler back-ends and related technologies like dynamic recompiling CPU simulators.

Assembly language programming is also used with some frequency for video game programming, to take advantage of new CPU features that are not yet well supported by current compilers. However, this is kind of rare, these days, especially since on PC's, there are so many different CPU's to support. I expect this is a bit more common on consoles with uniform hardware, though.

Edit: These days games do most of their calculation in a GPU. Getting the most out of these compute resources is not always possible using just OpenGL or DirectX, and the vendors for these processors provide a host of tools for squeezing more out of their hardware. Although Cuda or OpenCL are well known terms, they are still at a relatively high level of abstraction over the GPU hardware, filling in a role that is very similar to the role of C on typical (Von Neuman) CPU's. A look at the developer pages for these products and you will find dozens of ways to use GPU compute resources optimally, and at every level of abstraction.
