Dr. Unat's TEDx Istanbul Talk

Dr. Unat gave a talk on her research on supercomputing at an event organized by TEDx Istanbul on Oct 13th. The event, moderated by Emin Çapa, took place in Zorlu PSM and was attended by 2500 people. The video will be posted here when it gets online.

Congrats to Nufail for his Supercomputing 2018 (SC'18) paper 

Our paper titled "Phase Asynchronous AMR Execution for Productive and Performant Astrophysical Flows" has been accepted to appear at the prestiguous Supercomputing Conference held in Nov 2018 in Dallas, USA. Congrats to Nufail for this major achievement.

A new paper on high bandwidth memory will be presented at SBAC-PAD

Congrats to Mohammad for his paper accepted for presentation at SBAC-PAD, which is held in Sept in Lyon, France. The paper proposes a dynamic object placement algorithm for the KNL chip equipped with high bandwidth memory and high capacity memory. 

Determinacy Race Detection work will be presented at a major HPC conference.

Congrats to Hassan for his paper accepted for presentation at Europar, which is held in August in Turin, Italy. The paper proposes Runtime Determinacy Race Detection for OpenMP Tasks.

Congrats to ParCoreLab members for graduating Summer 2018

Five of our lab members are graduating this summer. Nufail and Hassan are earning their PhDs. Burak, Mohammad and Pirah are receiving their MS degrees.  Hassan will be joining ASML, the Advanced Semiconductor Materials International in Holland, Pirah is moving to Chalmers University, Sweden for pursuing her PhD, Mohammad is moving to Virgnia Tech, USA for pursuing his PhD. Congrats to ALL.
