Puas yog koj xav tau lub tshuab uas tuaj yeem xa ntau pua lab nyiaj ntawm kev suav cov ntsiab lus ib ntus? Puas yog koj xav tau cov dab neeg hais txog yuav ua li cas supercomputer hauv koj lub qab daus tig lub tsoo? Tsim koj tus kheej High Performance Compute pawg, aka supercomputer, yog qhov nyuaj rau txhua tus kws tshaj lij geek nrog lub asthiv ntawm lub sijhawm dawb thiab qee cov nyiaj ntsuab los hlawv tuaj yeem daws. Hais lus thev naus laus zis, thev naus laus zis thev naus laus zis niaj hnub no yog lub network ntawm cov khoos phis tawj ua haujlwm ua ke los daws teeb meem. Kab lus no yuav piav qhia luv luv txhua kauj ruam hauv tus txheej txheem, tsom mus rau kho vajtse thiab software.
Cov kauj ruam
Kauj Ruam 1. Ua ntej txiav txim siab cov cuab yeej kho vajtse thiab cov peev txheej xav tau
Koj yuav xav tau ib lub taub hau, tsawg kawg yog kaum ob tus lej sib xws, hloov Ethernet, chav faib hluav taws xob, thiab khib. Txiav txim siab qhov xav tau hluav taws xob, cua txias thiab qhov chaw xav tau. Kuj txiav txim siab qhov IP chaw nyob uas koj xav tau rau koj tus kheej cov tes hauj lwm, dab tsi rau npe cov nodes, cov software pob koj xav tau teeb tsa, thiab cov thev naus laus zis twg koj xav muab lub peev xwm suav ua ke (ntau ntxiv tom qab no).
- Txawm hais tias kho vajtse yog kim, txhua qhov software teev hauv no yuav ua li cas-dawb, thiab feem ntau yog qhib qhov chaw.
- Yog tias koj xav pom sai npaum li cas koj lub supercomputer yuav ua haujlwm zoo, siv qhov cuab yeej no:
Kauj Ruam 2. Tsim cov lej suav
Koj yuav tsum tau sib sau ua ke cov lej lossis tau txais cov servers ua ntej.
- Xaiv lub khoos phis tawj neeg rau zaub mov chassis uas ua rau qhov chaw loj tshaj plaws, txias, thiab ua haujlwm tau zoo.
- Lossis koj tuaj yeem siv kaum ob lossis siv li ntawd, cov servers qub dhau los - uas nws tag nrho yuav ntau dua qhov suav ntawm lawv qhov tseem tsis tau txuag koj li nyiaj ntau. Txhua tus txheej txheem, kev hloov pauv hauv network, thiab cov niam ntawv yuav tsum zoo ib yam rau tag nrho cov kab ke los ua ke kom zoo. Tau kawg, tsis txhob hnov qab txog RAM thiab cia rau txhua qhov ntawm thiab tsawg kawg ib qho kho qhov muag rau lub taub hau.
Kauj Ruam 3. Nruab cov servers rau hauv khib
Pib los ntawm hauv qab, yog li cov khib tsis hnyav hnyav. Koj yuav xav tau ib tus phooj ywg los pab koj txog qhov no - cov servers hnyav tuaj yeem hnyav heev thiab coj lawv mus rau hauv txoj kab uas tuav lawv rau hauv khib yog qhov nyuaj.
Kauj Ruam 4. Txhim Kho Ethernet hloov dua siab tshiab lub server chassis
Siv lub sijhawm no los teeb tsa qhov hloov pauv: tso cai rau jumbo thav duab qhov loj me ntawm 9000 bytes, teeb tus IP chaw nyob mus rau qhov chaw nyob zoo li koj tau txiav txim siab hauv theem 1, thiab tua cov txheej txheem tsis tseem ceeb xws li SMTP Snooping.
Kauj Ruam 5. Nruab PDU (Lub Hwj Huam Fais Fab)
Nyob ntawm seb muaj pes tsawg tam sim no koj cov node yuav xav tau ntawm qhov siab tshaj plaws, koj yuav xav tau 220 volts rau kev ua haujlwm siab.
Kauj Ruam 6. Nrog txhua yam teeb tsa, koj tuaj yeem pib txheej txheem teeb tsa
Linux yog de facto OS rau HPC pawg - tsis tsuas yog nws yog ib puag ncig zoo tshaj plaws rau kev suav xam, tab sis nws tsis raug nqi ib yam los teeb tsa nws ntawm ntau pua lossis ntau txhiab ntawm cov ntshav. Xav txog tias nws yuav raug nqi ntau npaum li cas rau nruab Windows ntawm txhua qhov ntawm no!
- Pib nrog kev txhim kho qhov tseeb version ntawm motherboard BIOS thiab firmware, uas yuav tsum zoo ib yam ntawm txhua qhov.
- Nruab koj qhov nyiam linux distro ntawm txhua lub node, nrog lub graphical UI rau lub taub hau. Kev xaiv nrov suav nrog CentOS, OpenSuse, Scientific Linux, RedHat, thiab SLES.
- Tus kws sau ntawv no pom zoo siv Rocks Cluster Distribution. Ntxiv rau kev txhim kho txhua yam cuab yeej tsim nyog rau kev suav ua pawg, Rocks siv txoj hauv kev zoo rau 'faib tawm' ntau qhov xwm txheej ntawm nws tus kheej mus rau cov nodes sai siv PXE khau raj thiab Red Hat 'Kick Start' txheej txheem.
Kauj Ruam 7. Txhim kho cov lus sib tham dhau los, tus tswj xyuas peev txheej, thiab lwm lub tsev qiv ntawv tsim nyog
Yog tias koj tsis tau teeb tsa Pob Zeb hauv cov kauj ruam dhau los, koj yuav tsum teeb tsa tus kheej cov software tsim nyog txhawm rau ua kom cov txheej txheem suav daws sib luag.
- Ua ntej koj yuav xav tau lub tshuab ua haujlwm tswj hwm pob, xws li Torque Resource Manager, uas tso cai rau koj kom tawg thiab faib cov haujlwm rau ntau lub tshuab.
- Pair Torque nrog Maui Cluster Scheduler kom ua tiav kev teeb tsa.
- Tom ntej no koj yuav tsum tau teeb tsa cov lus hla kev sib tham, tsim nyog rau tus kheej cov txheej txheem ntawm kev cais cov lej sib txawv los qhia tib cov ntaub ntawv. OpenMP yog qhov tsis nkag siab.
- Tsis txhob hnov qab cov tsev qiv ntawv ua lej ntau xov thiab ua ke los tsim koj cov phiaj xwm kev sib dhos. Kuv puas tau hais tias koj yuav tsum cia li teeb tsa Pob Zeb?
Kauj Ruam 8. Network cov lej suav ua ke
Lub taub hau ntawm lub chaw xa cov haujlwm ua haujlwm rau cov lej suav, uas yuav tsum xa cov txiaj ntsig rov qab, nrog rau xa xov mus rau ib leeg. Qhov nrawm dua zoo dua.
- Siv lub network ethernet ntiag tug los txuas txhua lub node hauv pawg.
- Lub taub hau kuj tseem tuaj yeem ua NFS, PXE, DHCP, TFTP, thiab NTP server hla Ethernet network.
- Koj yuav tsum cais lub network no los ntawm cov koomhaum pej xeem, uas ua kom ntseeg tau tias pob ntawv tshaj tawm tsis cuam tshuam nrog lwm lub network hauv koj LAN.
Kauj Ruam 9. Ntsuas pawg
Qhov kawg uas koj yuav xav ua ua ntej tso tawm txhua qhov kev suav no rau koj cov neeg siv yog sim nws qhov kev ua tau zoo. HPL (Kev Ua Tau Zoo Lynpack) qhov ntsuas yog qhov kev xaiv zoo rau ntsuas ntsuas kev suav ntawm cov pawg. Koj yuav tsum tau suav nws los ntawm qhov chaw nrog txhua qhov ua tau zoo tshaj plaws uas koj tus neeg muab khoom muab rau cov qauv vaj tsev uas koj tau xaiv.
- Koj yuav tsum, tau kawg, suav sau los ntawm qhov chaw nrog txhua qhov ua tau zoo xaiv rau koj lub platform. Piv txwv li, yog siv AMD CPUs, suav nrog Open64 nrog -0 qib kev ua kom zoo dua qub.
- Sib piv koj cov txiaj ntsig ntawm TOP500.org txhawm rau sib piv koj pawg mus rau 500 supercomputers nrawm tshaj plaws hauv ntiaj teb!
Yees duab - Los ntawm kev siv qhov kev pabcuam no, qee cov ntaub ntawv yuav raug muab qhia rau YouTube
Lub tswv yim
- Rau qhov network siab heev, saib mus rau hauv InfiniBand network cuam tshuam. Npaj kom them tus nqi hwm txawm hais tias.
- IPMI tuaj yeem ua thawj coj ntawm pawg loj ua kom yooj yim los ntawm kev muab KVM-dhau-IP, kev siv hluav taws xob nyob deb, thiab ntau ntxiv.
- Siv Ganglia los tshuaj xyuas cov lej suav ntawm cov nodes.
