Sannadkii hore ee St. Petersburg waxaa jiray , oo loogu talagalay nidaamyada isbarbar-dhigga iyo qaybsan. Abaalmarintu waxay sameeyeen bandhigyo и (, и ), abuurayaasha isku-dubaridyada iyo luqadaha barnaamijyada (C ++, Go, Java, Kotlin), soo-saareyaasha xogta la qaybiyay (Cassandra, CosmosDB, Yandex Database), iyo sidoo kale abuurayaasha iyo cilmi-baarayaasha algorithms iyo qaab-dhismeedka xogta (CRDT, Paxos, sug -qaababka xogta bilaashka ah) . Guud ahaan, meeshan waxaad mar hore qaadan kartaa fasax, yaree daaqadda IDE, ku fur liiska heesaha YouTube-ka Hydra 2019 - oo ha yara sugo jadwalaha hawsha.
Guud ahaan shirkan oo kale marna ma dhicin, haddana wuu soo laaban doonaa. Mar labaad oo leh warbixino Ingiriisi ah, sababtoo ah ma jiro luuqad ka fiican oo looga hadlo xisaabinta barbar-dhigga iyo qaybinta. Mar labaad xagaaga, Luulyo 10-keeda iyo 11-keeda, sababtoo ah dadka ku hadlaa waxay haystaan wakhti ay ku baaraan oo wax ku dhigaan, tusaale ahaan, jaamacadaha Cambridge, Rochester iyo St. Petersburg, iyo wakhtiyada kale ee sanadka iyaga maaha.
Si kastaba ha ahaatee, markan Hydra waxaa lagu qaban doonaa Moscow, halkaas oo inta badan ka qaybgalayaasha shirku ay yimaadeen sannadkii hore si ay u dhagaystaan warbixinno ku saabsan heshiis la qaybiyay iyo xusuusta macaamilka. Hydra cusub waxaa ku jira barnaamij aad u adag, ku hadla cusub oo ay weheliyaan geesiyaashii sannadkii hore, iyo sidoo kale dareenka hore loo yaqaan ee xamaasadda hardcore barbar socda qaybiyay ka qaybgalayaasha saddex hoolal.
Aynu isla markiiba miiska saarno kaadhadhka sagxadda ah oo ay ku wajahan yihiin jeneraalada Byzantine - waxaan rabnaa in barnaamijka Hydra cusub uu noqdo mid faahfaahsan oo kala duwan. Markii ugu dambeysay waxaan ku xoqnay ciddi, hadda aan sii qoto dheereyno oo qoto dheer. Waa kuwan mawduucyada Hydra 2020 oo leh faraq u dhexeeya sannadkii hore:
Parallel systems:
* Algorithms & data structures
* Memory models
* Compilers, runtime
* Memory reclamation
* Testing & verification
* Hardware issues
* Non-volatile memory
* Transactional memory
* Scheduling algorithms & implementations
* Heterogeneous computing: CPU, GPU, FPGA, etc.
* Performance analysis, debugging, & optimization
Distributed systems:
* Distributed computing
* Distributed machine learning/deep learning
* State machine replication & consensus
* Fault tolerance & resilience
* Testing & verification
* Hardware issues
* Blockchain & Byzantine fault tolerance
* Distributed databases, NewSQL
* Distributed stream processing
* Scheduling algorithms & implementations
* Cluster management systems
* Security
* Performance analysis, debugging, & optimization
* Peer-to-peer, gossip protocols
* Internet of things
Sida looga hadlo waxaas oo dhan barnaamijka hal shir? Dhab ahaantii kama fududa in la tijaabiyo toosnaanta hawlgallada ee dukaan cusub oo dhalaalaya oo la qaybiyey iyadoo la isticmaalayo , laakiin waan isku dayi doonaa.
Waa kan cidda horay ugu jirtay barnaamijka:
(Cindy Sridharan) - soo-saare nidaamyada qaybiyay oo ka yimid San Francisco, qoraa buug gaaban (qaado ) oo caan ah , halkaas oo uu jiro hal maqaal oo kaliya ""Waxay kaa badbaadin kartaa dhawr maalmood oo fasax ah, laakiin waxay kaa tagtaa farxad. Hydra 2020, Cindy ayaa kuu sheegi doonta sida , xitaa haddii ay kaydiyaan gobolka.
Michael Scott (Michael Scott) - cilmi baare ka , loo yaqaan dhammaan horumarinta Java sida abuuraha oo ka socda Maktabadda Heerka Java. Dabcan, oo leh abaalmarinta Dijkstra ee ""oo leh . Sannadkii hore, Michael wuxuu bixiyay warbixintii ugu wacnayd (sida aad adigu leedahay) ee Hydra , oo hadda wuu ka hadli doonaa и , diyaar u ah hababka barbar socda.
(Heidi Howard) - ka , oo caan ku ah abuurista algorithm la isku raacsan yahay oo la qaybiyey , iyo sidoo kale ka shaqaynta guud ee Paxos Flexible iyo . Sannadkii hore, Heidi wuxuu sheegay sida ay u shaqeyso iyo sida ay u shaqeyso (mid ka mid ah warbixinnada ugu fiican), oo hadda waxaan isku dayi doonaa inaan ku socdo baraf khafiif ah oo u dhexeeya - oo la wadaag ra'yigiisa ku saabsan algorithm ka fiican.
(Martin Kleppmann) waxaa laga yaabaa inuu yahay cilmi-baare aad caan ah oo ka socda Jaamacadda Cambridge, iyo horumariye hore ee nidaamyada xogta waaweyn, kaasoo qoray buug si la yaab leh oo cad oo sidaas darteed buug gaar ah oo ku saabsan nidaamyada la qaybiyey "" Sannadkii hore Martin ee cilmi-baaristooda CRDT, iyo waxa aan hadda kuu sheegi doono .
(Nikita Koval) waa horumariye ka tirsan kooxda Kotlin, macalin koorso ku saabsan barnaamijyo taxane badan oo ITMO ah, iyo xubin ka tirsan guddiga barnaamijka ee shirka Hydra (haa, midda maqaalkani wuxuu ku saabsan yahay). Sannadkii hore Nikita wuxuu ka hadlay tijaabinta qaababka xogta isku dhafan ee madal JVM iyadoo la adeegsanayo , iyo Hydra 2020 isaga ku saabsan SegmentQueueSynchronizer - la xaqiijiyay iyadoo la isticmaalayo si ay u abstraction for programming synchronization primitives.
Raac ogaysiisyadayada ismaandhaafka ah: guud ahaan waxa shirka ka soo bixi doona ilaa saddex iyo toban warbixinood, waxaanu idiin sheegi doonaa inta hadhay dhawaan. Sidoo kale, dabcan, shirka waxaa jiri doona goobo doodo ah oo ay lagama maarmaan tahay in dadka hadlaya lagu tijaabiyo su'aalo hal ama dhowr mawduuc ah ilaa laga gaarayo heshiis guud.
Haddii aad nasiib leedahay, Martin Kleppmann ayaa saxeexi doona buuggaaga.
Haa, kahor shirka Hydra 2020, kaas oo ah Luulyo 6-9, waxaa jiri doona - dugsiga xagaaga saddexaad ee aragtida iyo dhaqanka xisaabinta qaybiyey. Waxay ku siin doontaa dareeno ay adag tahay inaad ka hesho shirka, markaa waxaan uga hadli doonaa dugsiga qoraal gaar ah.
Maxaa hadda? Marka hore, la soco wararka Habré iyo shabakadaha bulshada (, , ).
Marka labaad, haddii aad horeba u dareentay rabitaan aan la adkaysan karin inaad ka qaybgasho shirka, baadh website-ka, waxaad hore u kari kartaa .
Saddex, ha lumin fursadda aad kula hadasho guddiga barnaamijka shirarka Hydra 2020 faallooyinka. Xubnaha PC ayaa ku farxi doona inay kaala hadlaan mawduucyada shirka mustaqbalka.
Ku arag Hydra!
