  The moving computation on the edge or near to data is the new trend that can
break the bandwidth wall and to unleash the power of next generation NVM or SCM
memory. File system is the important OS subsystem that plays the role of
mediator between the user-space application and storage device. The key goal of
the file system is to represent the file abstraction and to build the files'
namespace. In the current paradigm the file system needs to copy the metadata
and user data in the DRAM of the host with the goal to access and to modify the
user data on the host side. The DAX approach doesn't change the concept but to
build the way to bypass the page cache via the direct access to file's content
in persistent memory. Generally speaking, for the case of data-centric
computing, the file system needs to solve the opposite task not to copy data
into page cache but to deliver the processing activity near data on the storage
device side.
