Jan Czochralski pronounced cho HRAL skee October 23, 1885, Kcynia Exin , Poland April 22, 1953, Pozna was a Poland Polish chemistry chemist who invented the Czochralskiprocess , which is used to grow single crystal s and is used in the production of semiconductor wafers. Czochralski was born in Kcynia , then in the Prussia n Province of Pomerania 1815 1945 Province of Pomerania . Around 1900 he moved to Berlin , where he worked at a pharmacy. He was educated at Charlottenburg Polytechnic in Berlin, where he specialized in metal chemistry. Czochralski began working as an engineer for Allgemeine Elektrizit ts Gesellschaft AEG in 1907. He discovered the Czochralski method in 1916, when he accidentally dipped his pen Fact date October 2008 into a crucible of molten tin rather than his inkwell . He immediately pulled his pen out to discover that a thin thread of solidified metal was hanging from the Nib pen nib . The nib was replaced by a capillary, and Czochralski verified that the crystallized metal was a single crystal. The experiments of Czochralski produced single crystals that were a millimeter in diameter and up to 150 centimeters long. Czochralski published a paper on his discovery in 1918 in the Zeitschrift f r Physikalische Chemie , a German chemistry journal, under the title Ein neues Verfahren zur Messung der Kristallisationsgeschwindigkeit der Metalle A new method for the measurement ... its use in producing suitable semiconductors.

for process groups in data replication Virtual synchrony In POSIX conformant operating system s, a process group denotes a collection of one or more process computing process es. Process groups are used to control the distribution of signal computing signal s. A signal directed to a process group is delivered individually to all of the processes that are members of the group. Process groups are themselves grouped into sessions . Process groups are not permitted to migrate from one session to another, and a process may only create new process groups belonging to the same session as it itself belongs to. Processes are not permitted to join process groups that are not in the same session as they themselves are. New process images created by a call to a function of the code Exec operating system exec code family inherit the process group membership and the session membership of the old process image.

A child process in computing is a process created by another process the parent process . A child process inherits most of its Attribute computing attribute s, such as open computer file file s, from its parent. In Unix UNIX , a child process is in fact created using fork operating system fork as a copy of the parent. The child process can then overlay operating system overlay itself with a different program using tt Exec operating system exec tt as required. Each process may create many child processes but will have at most one parent process if a process does not have a parent this usually indicates that it was created directly by the kernel computer science kernel . In some systems, including UNIX based systems such as Linux , the very first process called init is started by the kernel at booting time and never terminates see Linux startup process other parentless processes may be launched to carry out various daemon computing daemon tasks in userspace . Another way for a process to end up without a parent is if its parent dies, leaving an orphan process but in this case it will shortly be adopted by init.
