Zstd is the corresponding reference implementation in C, released as open-source software on 31 August 2016. [ 3 ] [ 4 ] The algorithm was published in 2018 as RFC 8478 , which also defines an associated media type "application/zstd", filename extension "zst", and HTTP content encoding "zstd".
z/OS File System (zFS) (official name: z/OS® Distributed File Service zSeries® File System) is a POSIX-style hierarchical file system for IBM's z/OS operating system for z System mainframes, a successor to that operating system's HFS. [1]
ZFS (previously Zettabyte File System) is a file system with volume management capabilities. It began as part of the Sun Microsystems Solaris operating system in 2001. Large parts of Solaris, including ZFS, were published under an open source license as OpenSolaris for around 5 years from 2005 before being placed under a closed source license when Oracle Corporation acquired Sun in 2009–2010.
Oracle ZFS is Oracle's proprietary implementation of the ZFS file system and logical volume manager for Oracle Solaris. ZFS is a registered trademark belonging to Oracle. ZFS is a registered trademark belonging to Oracle.
As the FSF (Free Software Foundation) claimed that there was a legal incompatibility between the CDDL and the GPL in 2005, Sun's implementation of the ZFS file system couldn't be used as a basis for the development of a module in the Linux kernel, couldn't be merged into the mainline Linux kernel, and Linux distributions generally did not include it as a precompiled kernel module.
Zero-copy programming techniques can be used when exchanging data within a user space process (i.e. between two or more threads, etc.) and/or between two or more processes (see also producer–consumer problem) and/or when data has to be accessed / copied / moved inside kernel space or between a user space process and kernel space portions of operating systems (OS).
An IBM System Z10 mainframe computer on which z/OS can run. z/OS is a 64-bit operating system for IBM z/Architecture mainframes, introduced by IBM in October 2000. [2] It derives from and is the successor to OS/390, which in turn was preceded by a string of MVS versions.
Most modern CPUs feature single instruction, multiple data (SIMD) instruction sets (Streaming SIMD Extensions, AltiVec etc.) where 128-bit vector registers are used to store several smaller numbers, such as four 32-bit floating-point numbers. A single instruction can then operate on all these values in parallel.
