NVM Express over Fabrics (NVMe-oF) is the concept of using a transport protocol over a network to connect remote NVMe devices, contrary to regular NVMe where physical NVMe devices are connected to a PCIe bus either directly or over a PCIe switch to a PCIe bus.
A key advance in improving performance is to allow those fast instructions to be performed while the others are waiting for data. This means the instructions are no longer completed in the order they are specified in the machine code, they are instead performed out-of-order. Consider this piece of code running on an out-of-order CPU:
[2] [3] The invention was conceived at the request of the United States Air Force to come up with a more flexible and secure way of storing the targeting constants in the Atlas E/F ICBM's airborne digital computer. The patent and associated technology were held under secrecy order for several years while the Atlas E/F was the main operational ...
Alias analysis is a technique in compiler theory, used to determine if a storage location may be accessed in more than one way. Two pointers are said to be aliased if they point to the same location. Alias analysis techniques are usually classified by flow-sensitivity and context-sensitivity. They may determine may-alias or must-alias information.
An alias will last for the life of the shell session. Regularly used aliases can be set from the shell's rc file (such as .bashrc) so that they will be available upon the start of the corresponding shell session. The alias commands may either be written in the config file directly or sourced from a separate file.
Aliasing can occur in any language that can refer to one location in memory with more than one name (for example, with pointers).This is a common problem with functions that accept pointer arguments, and their tolerance (or the lack thereof) for aliasing must be carefully documented, particularly for functions that perform complex manipulations on memory areas passed to them.
In classic Mac OS System 7 and later, and in macOS, an alias is a small file that represents another object in a local, remote, or removable [1] file system and provides a dynamic link to it; the target object may be moved or renamed, and the alias will still link to it (unless the original file is recreated; such an alias is ambiguous and how it is resolved depends on the version of macOS).
It is the responsibility of this layer to perform block allocation, wear leveling, garbage collection, crash recovery, address translation and also to make the address translation data structures persistent.
