hott spott (computer prograaming)

computer vigyaan mein ack hott spott koo aamtaur parr ack computer prograam key usa kshetra key roop mein paribhaashit kiya jaataa haye jahaan nishpaadit nirdeshon kaa ack uchch anupaat hotaa haye yaa jahaan prograam key nishpaadan key dauran adhikansh samay bitaaya jaataa haye (jaruri naheen kii vahee baat hoe kyonki kuchh nirdesh dusaron kii tulanaa mein tej houn).
yadi koee prograam yaadrichhik roop seey baadhit hotaa haye, tou prograam counter (nishpaadit kiye jaane vaale agale nirdesh key liye soochak) mein aksar ack nishchit seema key bheetar ack nirdesh kaa pataa paaya jaataa haye, sambhavatah code kaa sanket detaa haye jise anukoolan kii aavashyakta haye yaa yahaan taka kii ack 'tanga' cpu loop key astitva kaa sanket bhee detaa haye. yeh saral takneek atyadhik upayog kiye gaye nirdeshon kaa pataa lagaa sakati haye, halanki adhik parishkrit tareeke, jaise kii nirdesh sett simulator yaa pradarshan vishleshak, ise adhik sateek aur lagaatar praapt karate hain.
hott spott kaa pataa lagaane kaa itihas.
computer vaigyaanik donald naath ney "dow. 1996 mein dobb kii patrika ", kaha rahee haih
60 key dashak mein, kissy ney 'jump trace' kii avadharana kaa aavishkaar kiya. yeh ack prograam kii machine bhasha koo badalane kaa ack tarika thaa taaki yeh niyantran banaae rakhane key liye agali shakha koo badal dey yaa nirdesh koo badhaa dey, taaki aap ack samay mein pratyek nirdesh kii vyakhya karane key bajaay prograam koo kaafee tej gati seey nishpaadit curr sakein aur ack file mein record curr sakein jahaan ack prograam anukramata seey alag hoe gayaa thaa. iss file koo sansaadhit karke aap yeh pataa lagaa sakate hain kii karyakram apana adhikansh samay kahaan bitaa rhaa thaa. isaliye pahale dinn jaba hamaare paas yeh software chala rhaa thaa, hamane ise apane fortran compiler parr lagu kiya, mujhe lagata haye kii una dinon yeh detta nigam koo niyantrit kartaa thaa. hamein pataa chalaa kii yeh apana 87 pratishat samay tippaniyon koo padhane mein lagaa rhaa thaa! iska kaaran yeh thaa kii yeh ack code pranali seey doosari mein anuvaad curr rhaa thaa.
punaravritti.
uparokt udaaharan yeh spasht karane kaa kaam kartaa haye kii prabhaavi hott spott kaa pataa lagaana aksar ack punaravritti prakriya hoti haye aur shayed ack aisee prakriya jise hamesha kiya jaanaa chaahiye (kewal yeh sweekaar karane key bajaay kii ack karyakram uchit roop seey pradarshan curr rhaa haye). sabhi baahari prasanskaran koo samaapt karane key baad (udaaharan key liye sabhi antarnihit tippaniyon koo hataakar), ack nayaa runtime vishleshan anuvaad mein "vaastavik" hott spott kaa adhik sateek roop seey pataa lagaayega. yadi koee hott spott kaa pataa naheen chalaa hotaa, tou karyakram ney aavashyakta seey kaheen adhik sansadhanon kii khapat kii hogi, sambhavatah kaee varshon taka kaee machines parr, binaa kissy koo isake baare mein poori tarah seey pataa chaley.
ack hott spott detector key roop mein anudesh sett simulation.
ack nirdesh sett simulator kaa upayog pratyek baar kissy vishesh nirdesh koo nishpaadit karane parr ganana karane key liye kiya jaa sakata haye aur baad mein yaa tou ack onn-screen display, ack mudrit prograam soochi (kull nirdesh path kii lambai kii ginati aur/yaa pratishat key saath) yaa ack alag report kaa utpaadan kiya jaa sakata haye, joe thheek seey dikhaata haye kii sabse adhik sankhya mein nirdesh kahaan hue they. yeh kewal hott spott kaa ack "saapeksh" drishya pradaan kartaa haye (ack nirdesh charan key drishtikon seey) kyonki adhikansh nirdeshon kaa kaee machines parr alag-alag samay hotaa haye. phir bhee yeh atyadhik upayog kiye jaane vaale code kaa ack upaay pradaan kartaa haye aur ack algorithm koo tune karate samay apane aap mein kaafee upayogi haye.
