Panzvimbo pekushandisa zvakapatsanurwa kukosha kwesimba rinoshanda uye rinoita simba, isu tichagadzira parameterized modhi uye togadzirisa aya ma paramita kuitira kuti anoshanda uye anoshanda anoshanda macurves kubva kune abstract modhi simulation ienderane neyakatsanangurwa modhi.
Tevere, isu tichaona kuti iyo abstract modhi inogona kugadziridzwa sei kuti ienderane nemhedzisiro yeiyo yakadzama modhi.
Iri ndiro basa redu. Isu tine abstract model yechikamu mune network yemagetsi. Patinoshandisa chiratidzo chakadaro chekutonga kwairi, kuburitsa ndiyo inotevera mhedzisiro yesimba rinoshanda uye rinoshanda.
Kana isu tikashandisa chiratidzo chimwechete kune yekuisa yemuenzaniso wakadzama, tinowana mibairo senge iyi.
Tinoda mhedzisiro yekuenzanisa uye yakadzama modhi kuti ienderane kuitira kuti tigone kushandisa iyo abstract modhi kukurumidza kudzokorora pane system modhi. Kuti tiite izvi, isu tichagadzirisa otomatiki maparamendi eiyo abstract modhi kusvika mhedzisiro inoenderana.
Kuti tiite izvi, isu tichashandisa SDO, iyo inogona kuchinja otomatiki paramita kudzamara mhedzisiro yeabstract uye yakadzama mamodheru aenderana.
Kuti tigadzirise zvigadziriso izvi, tichatevera matanho anotevera.
- Chekutanga, isu tinopinza zvinhu zvekunyepedzera zveiyo yakadzama modhi uye tosarudza idzi data yekufungidzira parameter.
- Isu tichazotaura kuti ndeapi ma parameter anoda kugadziridzwa uye kuseta parameter siyana.
- Tevere, isu tichaongorora ma paramita, ne SDO kugadzirisa ma parameter kusvika mhedzisiro inoenderana.
- Chekupedzisira, isu tinogona kushandisa imwe yekuisa data kusimbisa iyo parameter yekufungidzira mhinduro.
Iwe unogona kukurumidza kukurumidzira maitiro ekusimudzira nekugovera simulations uchishandisa parallel computing.
Iwe unogona kumhanyisa kuenzanisa kwakasiyana pamacores akasiyana e-multi-core processor kana pamakomputa masumbu. Kana iwe uine basa rinoda kuti iwe umhanye akawanda simulations β semuenzaniso, Monte Carlo ongororo, parameter kuenderana, kana kumhanya akawanda endege matenderedzwa - unogona kugovera aya ekufungidzira nekuamhanyisa pamuchina wepakati-kati kana komputa sumbu.
Muzviitiko zvakawanda, izvi hazvizove zvakanyanya kuoma pane kutsiva iyo loop mune script neinofanana ye loop, parfor. Izvi zvinogona kutungamirira kukukurumidza kukuru mukumhanya masimulation.
Tine muenzaniso wemambure emagetsi endege. Tinoda kuyedza network ino pasi pemamiriro ekushanda akasiyana-siyana - kusanganisira kutenderera kwendege, kukanganisa uye mamiriro ekunze. Isu tichashandisa PCT kumhanyisa bvunzo idzi, MATLAB kurongedza modhi yebvunzo yega yega yatinoda kumhanya. Isu tinozogovanisa masimulation pane akasiyana macores ekombuta yangu. Tichaona kuti bvunzo dzakafanana dzinopera nekukurumidza kupfuura dzakateedzana.
Heano matanho atichazofanira kutevera.
- Kutanga, isu tichagadzira dziva revashandi maitiro, kana avo vanonzi MATLAB vashandi, tichishandisa iyo parpool command.
- Tevere, isu tichagadzira parameter seti kune yega yega bvunzo yatinoda kumhanya.
- Isu tichamhanyisa masimulation kutanga zvakateerana, imwe mushure meimwe.
- Uye wozoenzanisa izvi nekumhanya similations mukufanana.
Zvinoenderana nemhedzisiro, iyo yakazara yekuyedza nguva muparallel modhi ingangoita ka4 kashoma pane inoteedzana modhi. Takaona mumagrafu kuti simba rekushandisa rinowanzova pamwero unotarisirwa. Iwo mapeaks anooneka ane hukama nemamiriro akasiyana etiweki kana vatengi vachibatidzwa nekudzimwa.
Mienzaniso iyi yaisanganisira miedzo yakawanda yatakakwanisa kumhanya nekukurumidza nekugovera mafanidzo pamhando dzakasiyana dzemakombuta. Izvi zvakatibvumira kuongorora huwandu hwechokwadi hwakasiyana-siyana hwemamiriro ekubhururuka.
Zvino zvatapedza chikamu ichi chegadziriro yekusimudzira, tichaona kuti tingaite sei kugadzirwa kwezvinyorwa zvenhanho yega yega, kuti tingaite sei bvunzo nekunyora mhedzisiro.
Magadzirirwo ehurongwa anogara ari maitiro ekudzokorora. Isu tinoita shanduko kune purojekiti, kuyedza shanduko, kuongorora zvabuda, tozoita shanduko itsva. Maitiro ekunyora zvawanikwa uye chikonzero chekuchinja chinotora nguva yakareba. Unogona otomatiki maitiro aya uchishandisa SLRG.
Uchishandisa SLRG, unogona kuita otomatiki maitirwo ebvunzo wobva watora mhedzisiro yebvunzo idzodzo muchimiro cheshumo. Chirevo chinogona kusanganisira kuongororwa kwemhedzisiro yebvunzo, zviratidziro zvemodhi uye magirafu, C uye MATLAB kodhi.
Ndichapedzisa nekurangarira pfungwa huru dzemharidzo iyi.
- Isu takaona mikana yakawanda yekumisikidza modhi kuti tiwane chiyero pakati pekuvimbika kwemuenzaniso uye kumhanya kwekuenzanisa-kusanganisira modhi yekufananidza uye nhanho yekubvisa modhi.
- Isu takaona maitiro atinogona kukurumidzira simulations tichishandisa optimization algorithms uye parallel komputa.
- Chekupedzisira, isu takaona maitiro atinogona kukurumidzira maitiro ekusimudzira nekuita otomatiki simulation uye kuongorora mabasa muMATLAB.
