The [Department of Computer Science and Engineering](https://cse.osu.edu/) at The Ohio State University has made major contributions to the field of high-performance computing for many years. Recently, our [Network Based Computing Lab](http://nowlab.cse.ohio-state.edu/) introduced two enhancements to further support the growth of computing on Power Systems.
|
|
|
|
## **High-Performance MPI and Deep Learning on OpenPOWER**
|
|
|
|
Our MVAPICH team now provides optimized support for OpenPOWER platforms with NVIDIA GPUs and NVLink to extract high-performance and scalability for MPI and Deep Learning applications. The latest MVAPICH2-GDR 2.3a release supports efficient CUDA IPC by exploiting multiple CUDA streams for multi-GPU systems with and without NVLink.
|
|
|
|
Highlights of this release include:
|
|
|
|
- Excellent MPI-level point-to-point communication for Device-to-Device (D-D), Device-to-Host (D-H) and Host-to-Host (H-H) paths, in addition to the CUDA-aware MPI design in the MVAPICH2-GDR library
|
|
- Unidirectional bandwidth up to 35,390 Mbytes/sec for intra-node D-D communication
|
|
- Bidirectional bandwidth up to 23,400 Mbytes/sec for inter-node D-D communication
|
|
- High-performance and scalable collective communication support for broadcast, reduce and all-reduce, the common collective operations in Deep Learning.
|
|
|
|
These features provide novel ways to extract the highest performance and scalability on the emerging CORAL systems with OpenPOWER, NVIDIA GPUs and InfiniBand.
|
|
|
|
More than 2,800 organizations in 85 countries already use the MVAPICH2 library, including Sunway TaihuLight, the #1 SuperComputer in the world. For more information on the MVAPICH2-GDR 2.3 library and its performance figures, please [visit our website](http://mvapich.cse.ohio-state.edu/).
|
|
|
|
## **RDMA-Hadoop Library Empowering OpenPOWER**
|
|
|
|
Our HiBD (High-Performance Big Data) team now provides optimized designs and support in the RDMA-Hadoop library for OpenPOWER platforms with the InfiniBand network. New designs and optimized techniques are included in the latest RDMA-Hadoop 2.x 1.3.0 library to exploit the OpenPOWER architecture.
|
|
|
|
Highlights of this release include:
|
|
|
|
- The proposed designs can achieve up to 2.26X performance improvement for Hadoop workloads, compared to the default designs running on OpenPOWER platforms.
|
|
- These features provide novel ways to extract the highest performance and scalability for big data workloads on the emerging OpenPOWER platforms with InfiniBand interconnect, such as upcoming CORAL systems.
|
|
|
|

|
|
We are excited for the opportunities provided by both these recent releases and look forward to future improvements to high-performance computing leveraging Power Systems.
