Center node: "dmath a scalable linear algebra and math library for heterogeneous gp gpu architectures"
  Abstract: A new scalable parallel math library, dMath, is presented in this paper that demonstrates leading scaling when using intranode, or internode, hybrid-parallelism for deep-learning. dMath provides easy-to-use distributed base primitives and a variety of domain-specific algorithms. These include matrix multiplication, convolutions, and others allowing for rapid development of highly scalable applications, including Deep Neural Networks (DNN), whereas previously one was restricted to libraries that provided effective primitives for only a single GPU, like Nvidia’s cublas & cudnn or DNN primitives from Nervana’s neon framework. Development of HPC software is difficult, labor-intensive work, requiring a unique skill set. dMath allows a wide range of developers to utilize parallel and distributed hardware easily. One contribution of this approach is that data is stored persistently on the GPU hardware, avoiding costly transfers between host and device. Advanced memory management techniques are utilized, including caching of transferred data and memory reuse through pooling. A key contribution of dMath is that it delivers performance, portability, and productivity to its specific domain of support. It enables algorithm and application programmers to quickly solve problems without managing the significant complexity associated with multi-level parallelism. dMath can use intranode GPU-Direct Remote Direct Memory Access (GDR), developed in collaboration with the OpenMPI and MVAPICH groups that has shown to decrease latency and increase bandwidth when compared to previous techniques. Efficient inter-GPU communication is crucial to achieving greater net performance and supporting effective use of the cost-effective, GPU-dense COTS architecture adopted. dMath’s caching approach addresses one of the key drawbacks of GPUs, which is to keep data sets cached and to avoid overheads of the CPU-GPU memory interface wherever possible. Keywords—GP-GPU, CUDA, MPI, deep learning, deep neural network, matrix-matrix multiplication, InfiniBand, scalability
