Ask HN: Why is there such little talk on Multicore/Machine Programming

This came to my attention after taking a mid level programming course were the professor stressed multi-core/machine programming and how most programs even today are not multi-core. Now I am trying to get into OpenMP (in C++) and there seems to be quite a lack of conversation and tutorials on the issue. (also with OpenCL and CUDA). Were are the multi-core/machine programmers at and is there a market for having that skillset on your resume?
