The NVIDIA DGX-1 deep learning system comprises a combination of hardware and software that delivers faster and more accurate training of neural networks. Purpose built for deep learning and AI analytics, the DGX-1 delivers performance equivalent to 250 conventional CPU-only servers.Configure DGX-1 Server
The second-generation of the DGX-1 is powered by eight NVIDIA Tesla V100 GPU accelerators which are based on the new Volta architecture. These cutting-edge GPUs combine both CUDA cores (5120) and the latest Tensor Cores (640) plus 16GB of RAM and are specifically designed for deep learning delivering a massive 5x speed up compared to the first-generation DGX-1.
NVLink unlocks the full performance of the eight Tesla V100 cards, so the DGX-1 delivers up to 960 teraFLOPs at half-precision (FP16), the most common format used in deep learning calculations. This is a dramatic speed up compared to deep learning on CPUs, saving you significant time and money.

The DGX-1 is much more than a GPU server, it is a deep learning solution comprising a finely tuned combination of hardware and software. Running a GPU-optimised version of Ubuntu Server Linux, the software stack comprises drivers, the NVDocker container tool, deep learning SDK, NVIDIA Cloud Management Service plus NVIDIA DIGITS which is used to run deep learning frameworks such as Caffe, Torch, TensorFlow and many more.
The Operating System (Ubuntu Server Linux) is optimised to take advantage of the hardware and software features of the system and CUDA 8, especially with respect to memory management and hardware communications.
The deep learning frameworks provided with the system are especially optimised to take advantage of the NVlink communication links among other enhancements, in order to optimize multi-GPU communication in the system.

If your workflow needs more compute performance multiple DGX-1 supercomputers can be linked together in a cluster. The DGX-1 hardware lends itself well to clustering as it is equipped with four 25Gb Infiniband EDR ports and two 10Gb Ethernet ports.
Clustering multiple DGX-1 servers requires high performance storage and networking to be able to deal with the high I/O demands of deep learning. Out of the box the DGX-1 runs the NFS file system however, it does support other file systems such as Lustre.
Building a DGX-1 cluster requires a head node/director to allocate jobs to the different nodes. We recommend using scheduling software such as Slurm on the head node/director.
Alternatively some deep learning software such as Caffe2 is designed to run in distributed mode, so you don’t need separate management software.
Whatever your requirements Scan’s data scientists and data centre engineers will be able to advise you on the best configuration for your cluster.
