NgoJulayi 11-12, okuwukuthi, ngaloLwesine nangoLwesihlanu, ingqungquthela izoba IHydra 2019. Lezi yizinsuku ezimbili namathrekhi amabili emibiko enikezelwe kukhompyutha esabalalisiwe. Le mibiko inikezwa ososayensi nonjiniyela abahamba phambili abeza eSt. Petersburg bevela emhlabeni wonke. Ingqungquthela ihloselwe ongoti kulo mkhakha, ayikho imibiko eyisingeniso!

Ungabuka ukusakazwa kwe-inthanethi kwamahhala ngokuphelele. Kuzoba njalo usuku lokuqala nehholo lokuqala + izingxoxo eziku-inthanethi phakathi kwemibiko. Sizoxoxa ngokuthi hlobo luni lwemibiko lena engaphansi kancane.

Kubalulekile ukuthi ukusakazwa kuzoqala ngo-9:45 am (isikhathi saseMoscow), imizuzu eyi-15 ngaphambi kokuvulwa, futhi kuzophela sekusondele ihora lesi-8 ebusuku. Sonke lesi sikhathi uzokwazi ukulalela imibiko enamakhefu amafushane. Isixhumanisi sizosebenza usuku lonke, ngakho-ke ungasivula kuphela emibikweni ebaluleke kakhulu kuwe.

Isixhumanisi sesayithi esinevidiyo nohlelo singaphansi kokusikwa. Lapho sizophinde sixoxe ngezinto ezimbalwa ezingeke zifakwe ekusakazeni, kodwa ezitholakala kubahlanganyeli abeza engqungqutheleni bukhoma.

Ungasakaza kuphi

Ikhasi lokusakaza lilinde kule nkinobho yesixhumanisi eluhlaza:

Kunesidlali sevidiyo nohlelo lwehholo lokuqala. Umdlali uzophila kuphela ekuseni ngoJulayi 11, manje akubonisi lutho.

Imibiko

Konke kuqala ngokhiye kaCliff Click "Isipiliyoni se-Azul Hardware Transactional Memory". UCliff uyinganekwane emhlabeni weJava, ubaba wokuhlanganiswa kwe-JIT kanye newizadi yokusebenza kwezinga eliphansi. Senze naye inhlolokhono enkulu ye-habroNgincoma ukuyifunda. Lona umbiko mayelana naleyo khompiyutha emangalisa kakhulu eyakhiwe emathunjini e-Azul.

Umbiko wesibili uvela ku-Ori Lahav wase-Tel Aviv University. Izintshisekelo zocwaningo zika-Ori zihlanganisa izilimi zokuhlela, ukuqinisekiswa okusemthethweni, futhi ikakhulukazi yonke into ehlobene nokufunda okuningi. embikweni "Ukuvumelana kwenkumbulo okubuthakathaka ku-C/C++11" Sizobheka ukuthi imodeli ye-multithreading ku-C++11 ichazwa kanjani ngokusemthethweni nokuthi ungaphila kanjani nezinkinga ezifana nokuphuma emoyeni.

Embikweni wesithathu, "Ukukhulula ukuvumelana okusabalalisiwe", u-Heidi Howard weNyuvesi yaseCambridge uzobuyela ezisekelweni zetiyori ze-Paxos, aphumule izidingo zangempela futhi enze jikelele i-algorithm. Sizobona ukuthi i-Paxos empeleni iyinketho eyodwa phakathi kohlu olukhulu lwezindlela zokuvumelana, nokuthi amanye amaphuzu ku-spectrum nawo awusizo kakhulu ekwakheni izinhlelo ezinhle ezisabalalisiwe. Ubuchwepheshe bukaHeidi buwukuvumelana, ukubekezelela amaphutha, ukusebenza, kanye nokuvumelana okusatshalaliswa.

“Yehlisa izindleko zakho zokugcina nge-Transient Replication kanye ne-Cheap Quorums” - lo mbiko ka-Alex Petrov mayelana nokuthi unganciphisa kanjani umthwalo kwisitoreji uma ugcina idatha kuphela engxenyeni yama-node, futhi usebenzisa ama-node akhethekile (I-Transient Replica) yokwehluleka ukuphatha izimo. Ngokuqhubeka kwenkulumo, sizobheka i-Witness Replicas, uhlelo lokuphindaphinda olusetshenziswa ku-Spanner ne-Megastore, kanye nokusetshenziswa kwalo mqondo ku-Apache Cassandra obizwa ngokuthi I-Transient Replication & Cheap Quorums.

U-Roman Elizarov wase-JetBrains uzokhuluma ngakho Ukuvumelana okuhleliwe. U-Roman uyiqembu eliholayo ekuthuthukisweni kwemitapo yolwazi yolimi lwase-Kotlin, ebandakanyeka mathupha ekwakhiweni nasekusetshenzisweni kwama-coroutines.

Futhi iphetha ukusakaza "Ama-Blockchains kanye nekusasa le-computing esabalalisiwe" - inothi eliyisihluthulelo likaMaurice Herlihy, usosayensi odume umhlaba wonke nobaba wenkumbulo yokuthengiselana. Senza noMaurice inhlolokhono enkulu ye-habro, okufanele uyifunde ngaphambi kokuba uye enkulumweni.

Ingqikithi: imibiko eyisithupha, inkumbulo yokuthengiselana, amamodeli enkumbulo, ukuvumelana okusabalalisiwe, ukuvumelanisa okuhlelekile ngisho nama-blockchains. Konke okudingayo ukuze ube nosuku oluhle.

Uma ufuna ukufinyelela kuyo yonke imibiko (hhayi nje ihholo lokuqala) ngoLwesine nangoLwesihlanu, ungakwazi thenga ithikithi le-inthanethi. Eqinisweni, leli yilo kuphela ithuba lalabo abasanda kufunda ngengqungquthela futhi ngeke babe nesikhathi sokufika eSt. Ngaphezu kwalokho, ngale ndlela uzoba nawo wonke amavidiyo aqoshiwe alokho okwenzekile. Imibiko eyinkimbinkimbi ibonakala ngokuthi cishe kuyodingeka ibuyekezwe.

Akuyona yonke into etholakalayo ekusakazeni

Uma ukwazi ukuthenga ithikithi ngomzuzu wokugcina futhi uze engqungqutheleni bukhoma, kuzoba nezinto ezimbalwa ezithokozisayo:

Izindawo zezingxoxo

Ngemva kombiko ngamunye, isikhulumi siya endaweni ekhethiwe yezingxoxo, lapho ungaxoxa khona futhi ubuze imibuzo yakho. Ngokusemthethweni, lokhu kungenziwa ngesikhathi sekhefu phakathi kwemibiko. Nakuba izikhulumi zingaphoqelekile ukuthi zikwenze lokho, ngokuvamile zihlala isikhathi eside - ngokwesibonelo, ngesikhathi sombiko wonke olandelayo. Ngezinye izikhathi kunengqondo ukweqa umbiko ovela ohlelweni oluyinhloko (uma uthenge ithikithi, usazoba namanothi ngemva kokugcwalisa impendulo) futhi uwuchithe engxoxweni egxilile nochwepheshe obalulekile.

Izikhathi ezimbili ze-BOF

I-BOF manje isiyifomethi yendabuko ezingqungqutheleni zethu. Okuthile okufana netafula eliyindilinga noma iqembu lezingxoxo lapho wonke umuntu angaba nengxenye khona. Le fomethi ngokomlando isuka kweyokuqala engakahleleki Amaqembu ezingxoxo ze-Internet Engineering Task Force (IETF).. Akukho ukwehlukana phakathi kwesikhulumi nomhlanganyeli: wonke umuntu ubamba iqhaza ngokulinganayo.

Okuhleliwe okwamanje izihloko ezimbili: “I-Modern CS emhlabeni wangempela” kanye nokuthi “Trade-offs in concurrency”. Womabili amaseshini e-BOF aqhutshwa ngesiNgisi kuphela, njengoba kunjalo neziningi zezethulo nezindawo zezingxoxo engqungqutheleni.

Indawo yombukiso

Lo mbukiso uyindawo yezitendi zezinkampani ezisebenzisana nezinkomfa. Lapha ungafunda ngamaphrojekthi athakazelisayo, ubuchwepheshe kanye nokusebenza eqenjini labaholi bemboni ye-IT. Lena indawo lapho wena nenkampani ningatholana khona. EHydra nathi I-Deutsche Bank Technology Center и Isifunda.

Iphathi ngobhiya nomculo

Ngokuhambisana nama-BOF, iphathi iqala ekupheleni kosuku lokuqala. Iziphuzo, ukudla okulula, umculo - konke ngesikhathi esisodwa. Ningaxoxa endaweni engahlelekile futhi nixoxe ngakho konke ngaphansi kwelanga. Ungasuka ku-buff uye ephathini. Ungasuka ephathini uye ku-bof.

Izinyathelo ezilandelayo

• Uma ubukele ukusakaza kwamahhala: udinga ukuhamba isixhumanisi ngoLwesine, Julayi 11. Ukusakaza kuzoqala ngabo-9:45 am ngesikhathi saseMoscow.
• Uma ufuna ukufinyelela kuyo yonke imibiko nokuqoshwa ngemuva kwengqungquthela: kufanele thenga ithikithi le-inthanethi.
• Uma ushintsha umqondo wakho bese uya bukhoma: usalelwe isikhathi esingaphansi kosuku ukuthi uthenge ithikithi, zonke izinketho ezingenzeka isixhumanisi.
