itihas.
linpack benchmark report pahali baar 1979 mein linpack upayogkarta key manual key parishisht key roop mein dikhaai dee.
linpack koo upayogkartaon koo linpack package kaa upayog karke ack samasya koo hull karane key liye unake system dwara aavashyak samay kaa anuman lagaane mein madad karane key liye design kiya gayaa thaa, 23 alag-alag computers dwara praapt pradarshan parinamon koo 100 aakar kii matricks samasya koo hull karke.
iss matricks kaa aakar usa samay smriti aur cpu seemaon key kaaran chunaa gayaa thaah
varshon seey, vibhinn samasya aakaron key saath atirikt sanskaran, jaise kii order 300 aur 1000 key matricks, aur baadhaon koo jaari kiya gayaa, jisase nae anukoolan key avsaron kii anumati millie kyonki hardware architecture ney matricks-vector aur matricks-matricks sanchaalan koo lagu karna shuru curr diyaa.
1980 key dashak key anta mein linpack samanantar benchmark mein samanantar prasanskaran bhee shuru kiya gayaa thaa.
1991 mein, linpack koo isake liye sanshodhit kiya gayaa thaa
manmaane aakar kii samasyaon koo hull karna, uchch pradarshan vaale computers (aich. pee. see.) koo unake asymptotic pradarshan key karib aaney mein saksham banaana.
dou saal baad iss benchmark kaa upayog pahali sheersh 500 soochi key pradarshan koo maapane key liye kiya gayaa thaa.

motey taur parr, algorithm mein nimnalikhit visheshtaen hainh
aalochana.
kahaa jaataa haye kii linpack benchmark aich. pee. ell. aaee. pee. key mapaniyata key kaaran safal huaa haye, yeh tathya kii yeh ack ekal sankhya utpann kartaa haye, jisase parinam aasaani seey tulaniya hoe jaate hain aur vyaapak aitihaasik detta aadhar isase judaa hotaa haye.
haalaanki, isake jaari honey key turant baad, linpack benchmark kii pradarshan star pradaan karane key liye aalochana kii gaee thee "aam taur parr sabhi dwara apraapya lekin bahut cumm programmer joe usa machine aur usa machine key liye apane code koo thakaau roop seey anukoolit karate hain", kyonki yeh kewal ghaney raikhik pranaliyon key resolution kaa pareekshan kartaa haye, joe aamtaur parr vaigyaanik computing mein kiye jaane vaale sabhi sanchaalan key pratinidhi naheen hain.
linpack benchmark key peechhe mukhya prerak bull jack dongra ney kahaa kii, jabaki way kewal "peak" cpu gati aur cpu kii sankhya parr jore dete hain, sthaaniya bandwidth aur network koo paryaapt tanaav naheen diyaa jaataa haye.
thom dunning, junier.supercomputing anuprayogon key liye rashtriya kendra key nideshak ney linpack benchmark key baare mein yeh kahaa thaah "linpack benchmark una dilchasp ghatnaaon mein seey ack haye-lagbhag koee bhee joe isake baare mein jaanata haye vaha isaki upayogita kaa upahaas karega. way isaki seemaon koo samajhate hain lekin isamen munn kii baat haye kyonki yeh ack sankhya haye jise humm sabhi ney pichhale kuchh varshon mein kharida haye."
dongarra key anusaar, "sheersh 500 key aayojak benchmark reporting key dayare kaa vistaar karane key liye sakriya roop seey dekh rahey hain" kyonki "kissy diye gaye system key liye adhik pradarshan visheshta aur hastakshar shamil karna mahatvapurna haye.
sheersh 500 key liye benchmark kaa vistaar karane key liye jinn sambhaavanaon parr vichaar kiya jaa rhaa haye, unamen seey ack hpc challenge benchmark soot haye. petascale computers key aagaman key saath, prati sekand paar kiye gaye kinare linpack dwara maapa jaane vaale flop key poorak metrick key roop mein ubharane lagey hain. ack anya aisaa metrick aich. pee. see. jee. benchmark haye, jise dongra dwara prastaavit kiya gayaa haye.
chalane kaa samay mudda.
jack dongra key anusaar, aich. pee. ell. aaee. pee. key saath achche pradarshan parinam praapt karane key liye aavashyak samay badhane kii ummeed haye. 2010 mein aayojit ack sammelan mein unhone kahaa kii unhein ummeed haye kii kuchh varshon mein 2.5 dinon kaa samay lagega.
