Forschung

Supercomputer

Das Höchstleistungsrechnen (HPC – vom englischen High Performance Computing) beschäftigt sich mit der Lösung von schwierigen Problemen, die auf einzelnen Computer nicht lösbar sind. Sei es weil die Berechnung zu lange dauert oder der Speicher nicht ausreicht. Der besondere Augenmerk liegt dabei auf eine skalierbare parallele Kommunikation auf eine hohe Performance auf Knotenebene und das Auslassen von nicht benötigten Berechnungen.

Mit NAStJA ist ein Framework entstanden, welches effizient skalenübergreifende Simulationen durchführen kann. Zudem ist es so flexibel designet worden, das schnell experimentelle Lösungsansätze ausprobiert werden können. NAStJA ermöglicht es vollkommen autonom das Rechengebiet dynamisch anzupassen und kommt dabei ohne kollektive Kommunikationen aus.

Anwendungen

Kristalline Phasenfeldmethode

Klassische Phasenfeldmethode

Zelluläre Automaten für biologische Anwendungen
