outstanding packets transmitted acknowledgement receipt receiver yet received acknowledgements received congestion window expanded one tcp segment time till acknowledgement fails arrive sender assumes congestion window size instant network gets congested however high bandwidth network sustain quite large congestion window without choking slow start algorithm take quite time reach threshold –

prolog intended primarily declarative programming language program logic expressed terms relations represented facts rules computation initiated running query relations language first conceived alain colmerauer group marseille france early 1970s first prolog system developed 1972 colmerauer philippe roussel prolog one first logic programming languages remains popular among languages today several free commercial implementations available language used theorem proving expert systems term rewriting type systems automated planning well original intended field use natural language processing modern prolog environments support creation graphical user interfaces well administrative networked applications prolog well-suited specific tasks benefit rule-based logical queries searching databases voice control systems filling templates prolog program logic expressed terms relations computation initiated running query relations relations queries constructed using prolog single data type term relations defined clauses given query prolog engine attempts find resolution refutation negated query negated query refuted i.e. instantiation free variables found makes union clauses singleton set consisting negated query false follows original query found instantiation applied logical consequence program makes prolog logic programming languages particularly useful database symbolic mathematics language parsing applications prolog allows impure predicates checking truth value certain special predicates may deliberate side effect printing value screen programmer permitted use amount conventional imperative programming logical paradigm inconvenient purely logical subset called pure prolog well number extralogical features prolog single data type term terms either atoms numbers variables compound terms special cases compound terms iso prolog provides codice_11 codice_12 codice_13 codice_14 predicates type-checking prolog programs describe relations defined means clauses pure prolog restricted horn clauses two types clauses facts rules rule form head body read head true body true rule body consists calls predicates called rule goals built-in predicate codice_15 meaning 2-arity operator name codice_16 denotes conjunction goals codice_17 denotes disjunction conjunctions disjunctions appear body head rule clauses empty bodies called facts example fact cat tom equivalent rule cat tom true built-in predicate codice_18 always true given fact one ask tom cat things cats clauses bodies called rules example rule animal x cat x add rule ask things animals due relational nature many built-in predicates typically used several directions example codice_19 used determine length list codice_20 given list codice_21 well generate list skeleton given length codice_22 also generate list skeletons lengths together codice_23 similarly codice_24 used append two lists codice_25 given lists codice_26 codice_27 well split given list parts codice_28 given list codice_21 reason comparatively small set library predicates suffices many prolog programs general purpose language prolog also provides various built-in predicates perform routine activities like input/output using graphics otherwise communicating operating system predicates given relational meaning useful side-effects exhibit system example predicate codice_30 displays term screen execution prolog program initiated user posting single goal called query logically prolog engine tries find resolution refutation negated query resolution method used prolog called sld resolution negated query refuted follows query appropriate variable bindings place logical consequence program case generated variable bindings reported user query said succeeded operationally prolog execution strategy

failure particularly important long running applications executed failure-prone computing systems distributed computing checkpointing technique helps tolerate failures otherwise would force long-running application restart beginning basic way implement checkpointing stop application copy required data memory reliable storage e.g. parallel file system continue execution case failure application restarts need start scratch rather read latest state checkpoint stable storage execute two main approaches checkpointing systems coordinated checkpointing uncoordinated checkpointing coordinated checkpointing approach processes must ensure checkpoints consistent usually achieved kind two-phase commit protocol algorithm uncoordinated checkpointing process checkpoints state independently must stressed simply forcing processes checkpoint state fixed time intervals sufficient ensure global consistency need establishing consistent state i.e. missing messages duplicated messages may force processes roll back checkpoints turn may cause processes roll back even earlier checkpoints extreme case may mean consistent state found initial state so-called domino effect one original common means application checkpointing save state feature interactive applications user application could save state variables data storage medium time using either continue working exit

save work sort functionality became extremely important usability applications particular work could completed one sitting playing video game expected take dozens hours writing book long document amounting hundreds thousands pages work done long period time data entry document rows spreadsheet problem save state requires operator program request save non-interactive programs including automated batch processed workloads ability checkpoint applications also automated batch applications began handle tens hundreds thousands transactions transaction might process one record one file several different files need application restartable point without need rerun entire job scratch became imperative thus checkpoint/restart capability born number transactions processed snapshot checkpoint state application could taken point application failed next checkpoint could restarted giving checkpoint information last place transaction file transaction successfully completed application could restart point checkpointing would tend expensive generally done every record reasonable compromise cost checkpoint vs. value computer time needed reprocess batch records thus number records processed checkpoint might range 25 200 depending cost factors relative complexity application resources needed successfully restart application fti library aims provide computational scientists easy way perform checkpoint/restart scalable fashion fti leverages local storage plus multiple replications erasures techniques provide several levels reliability performance fti provides
