GPU-laskennan optimointi

2013

Näytönohjaimet, grafiikkasuorittimet, tarjoavat rinnakkaisen laskennan alustan, jossa voidaan suorittaa ohjelmakoodia satojen ydinten toimesta. Tämä alusta mahdollistaa matemaattisesti työläiden ongelmien ratkaisemisen tehokkaasti. Grafiikkasuorittimen rinnakkainen suoritusympäristö kuitenkin eroaa suuresti tietokoneen suorittimen peräkkäisestä suoritusympäristöstä. Ongelmien ratkaisemiseksi tehokkaasti rinnakkaisympäristössä on noudettava ohjelmointimenetelmiä, jotka soveltuvat erityisesti rinnakkaisympäristöön. Tässä työssä tarkastellaan rinnakkaisen laskennan perusteita, miten erilaiset ohjelmointimenetelmät vaikuttavat ohjelman suoriutumiseen grafiikkasuorittimella sekä miten voidaan sa…

Yleinen laskenta grafiikkasuorittimilla

2012

Esitellään nykyaikaisten grafiikkasuorittimien rakennetta, toimintaperiaatteita ja tutkitaan OpenCL:ää keinona käyttää niiden laskentakykyä yleisempään laskentaan. Toteutetaan osa JPEG-kuvanpakkausalgoritmia grafiikkasuorittimella OpenCL:n avulla.
