Bachelor

Research on GPU analytical performance model

Investigating different performance behavior of memory divergent and non-memory divergent GPU application

Proposed a memory divergence model (MDM)

Our MDM model significantly increase prediction accuracy compared to state-of-art GPU analytical model

Research on NoC congestion problem in GPUs

Observed inter-CTA locality in GPU applications

Proposed a intra-cluster colasecing (ICC) unit to track and colaesce misses from different SMs in a cluster to reduce NoC pressure

Analyzed interaction between different CTA scheduling policy and ICC unit

Research on fault-tolerance in Networks-on-Chip (NoC)

Fault tolerant routing algorithm research on NoC

Reliable NoC router design
