Linux C++: how to profile time wasted due to cache misses?
We have several users on the c开发者_运维技巧omputing nodes which are running quite slow in some times. Are there some utility which can tell that the code makes cache misses or give a some hints for the optimization? The most of the users are coding in C++/C and F77/F90(some times with openmp).
