Chimwe chikamu chemudziyo wevacuum (iyo plasma inotarisana nezvinhu) yefusion yekuedza mudziyo uye remangwana remusanganiswa reactor rinosangana neplasma. Kana maion eplasma achipinda mune izvo zvinhu, izvo zvimedu zvinova atomu isina kwazvakarerekera uye zvinogara mukati mechinhu. Kana zvikaonekwa kubva kumaatomu anoumba zvinhu, maion eplasma akapinda anova maatomu etsvina. Maatomu etsvina anofamba zvishoma nezvishoma munzvimbo dziri pakati pemaatomu anoumba zvinhu uye pakupedzisira, anopararira mukati mechinhu. Kune rumwe rutivi, mamwe maatomu ekusachena anodzokera pamusoro uye anobudiswa zvakare kuplasma. Pakuvharirwa kwakagadzikana kweplasma yefusion, chiyero chiri pakati pekupinzwa kwemaion eplasma muchinhu uye kuburitswazve kwemaatomu etsvina mushure mekutama kubva mukati mechinhu kunova kwakakosha zvakanyanya.

Nzira yekufambisa yemaatomu etsvina mukati mezvishandiso zvine chimiro chekristaro chakanyatsojekeswa mukutsvagisa kwakawanda. Nekudaro, zvinhu chaizvo zvine zvimiro zvepolycrystalline, uyezve nzira dzekutama munzvimbo dzemuganho wezviyo dzakanga dzisati dzajekeswa. Kupfuurirazve, muchinhu chinoramba chichibata plasma, chimiro chekristaro chinoputsika nekuda kwekunyanya kupinza kweiyo plasma ion. Nzira dzekutama dzemaatomu etsvina mukati mechinhu chine hutsinye hwekristaro chimiro chaive chisina kuongororwa zvakakwana.

Boka rekutsvagisa raMuzvinafundo Atsushi Ito, weNational Institutes of Natural Sciences NIFS, rakabudirira kugadzira nzira yekutsvaga otomatiki uye nekukurumidza maererano nenzira dzekutama mumidziyo ine atomu geometry yeatomu kuburikidza nemamolecular dynamics uye maverengero akafanana mune supercomputer. Chekutanga, ivo vanotora akati wandei madiki madomasi anofukidza zvese zvinyorwa.

Mukati menzvimbo diki yega yega vanoverengera nzira dzekutama dzemaatomu etsvina kuburikidza nemamolecular dynamics. Iwo maverengero emadomasi madiki achapedzwa munguva pfupi nekuti saizi yedomeini idiki uye huwandu hwemaatomu anogadziriswa hauna kuwanda. Nekuti maverengero ega ega diki domain anogona kuitwa akazvimirira, kuverenga kunoitwa nenzira yakafanana uchishandisa iyo NIFS supercomputer, iyo Plasma Simulator, uye HELIOS supercomputer system paComputational Simulation Center yeInternational Fusion Energy Research Center (IFERC-CSC), Aomori, Japani. PaPlasma Simulator, nekuti zvinokwanisika kushandisa zviuru makumi manomwe zveCPU cores, panguva imwe chete kuverenga pamusoro pe70,000 domains inogona kuitwa. Kubatanidza mhedzisiro yese yekuverenga kubva kune madiki madiki, nzira dzekutama pamusoro pezvinhu zvese zvinowanikwa.

Nzira yakadaro yekufananidza yekombuta yepamusoro inosiyana neiyo inowanzoshandiswa, uye inonzi MPMD3) -rudzi parallelization. PaNIFS, nzira yekunyepedzera inoshandisa MPMD-mhando parallelization yakatsanangurwa. Nekubatanidza kuenzanirana nemazano achangoburwa maererano neautomatization, vasvika kune yakakwirira-kumhanya otomatiki yekutsvaga nzira yekufamba.

Nekushandisa nzira iyi, zvinogoneka kutsvaga nyore nzira yekutama yemaatomu ekusachena kwezvinhu chaizvo zvine miganho yezviyo zvekristaro kana kunyange zvinhu izvo chimiro chekristaro chinokanganiswa nekusangana kwenguva refu neplasma. Tichiongorora mafambiro ekufamba kwakabatana kwemaatomu etsvina mukati mezvinhu zvichibva paruzivo rwenzira iyi yekutama, tinogona kudzamisa ruzivo rwedu maererano nechiyero chechikamu chiri mukati meplasma uye zvinhu. Saka kuvandudzwa kwekuvharirwa kweplasma kunotarisirwa.

Mhedzisiro iyi yakapihwa muna Chivabvu 2016 pa22nd International Musangano wePlasma Surface Interaction (PSI 22), uye ichaburitswa mumagazini Nuclear Materials and Energy.
