Grand Challenge (Large Scale GPU applications)

Large scale Phase-Field simulation for metal dendritic solidification by multi-GPU computing

The phase-field method is applied to study dendritic solidification of Si-Al binary alloy. The performance reaches 2.0000045 PFLOPS for 4,096x6,500x10,400 mesh, which is the first over peta-scale result as a real stencil application we know to date.

Ultra-fast computing pipeline for metagenome analysis with next-generation DNA sequencers (NEW!)

Metagenome analysis is the study of the genomes of uncultured microbes obtained directly from microbial communities in their natural habitats. GHOSTM (K=4) as a homology search program, the pipeline achieves to process about 60 million reads per an hour with 2,520 GPUs (840 computing nodes) . Our results indicate the pipeline can process genome information obtained from a single run of next generation sequencers in a few hours.

Molecular Dynamics Simulation of a Biomolecule with High Speed, Low Power and Accuracy using GPGPU

Using GPUs could yield a great improvement in both the calculation speed and energy consumption. Comparing 8 nodes 16 GPUs result and 8 nodes 96 CPU cores result, we could achieve about 10 times acceleration and 75 % energy reduction. The results of GPU molecular dynamics was consistent with that of CPU molecular dynamics within acceptable range.
