IBM NeXtScale System Planning and Implementation Guide
NVIDIA offers several families of GPUs, two of which apply to the nx360 M4:
򐂰
NVIDIA GRID family: Professional-grade virtualized graphics
NVIDIA GRID GPU cards are designed to produce a crisp, responsive, and
professional graphics experience. GRID cards expand the advantages of
virtualization from the data center to the machine level, with management
functions and drivers to allow multiple users and VMs can share GPU
resources.
The nx360 M4 supports two NVIDIA GRID options:
– GRID K2: A dual-slot, 10.5 inch PCI Express Gen3 graphics card with two
high-end NVIDIA Kepler GPUs. The GRID K2 features 8 GB of GDDR5
memory (4 GB per GPU), and a 225 W maximum power limit.
– GRID K1: A dual-slot, 10.5 inch PCI Express Gen3 graphics board with
four NVIDIA Kepler GPUs. The GRID K1 has 16 GB of DDR3 memory (4
GB per GPU), and a 130 W maximum power limit.
򐂰 NVIDIA Tesla family: Scientific-grade computation and analytics
NVIDIA Tesla GPU cards are built to achieve extremely accurate results and
withstand long periods of intensive use. The Tesla drivers are coded
specifically for scientific-quality computation, and the cards are designed both
physically and logically for server deployment.
The nx360 M4 supports three NVIDIA Tesla options:
– Tesla K40: Features 12 GB of memory for demanding HPC and Big Data
analysis. It also includes a Tesla GPUBoost3 feature that makes it
possible to convert power headroom into increased performance.
– Tesla K20X: Designed for double-precision applications across the
supercomputing market. The K20X delivers greater than 1.31 TFlops peak
double-precision performance.
– Tesla K10: Optimized for single-precision applications. The Tesla K10
combines two ultra-efficient Kepler GPUs to provide high throughput for
computations in seismology, signal image processing, and video analytics.
Table 4-22 on page 95 provides additional details about each of the NVIDIA
GPUs that can be used with an nx360 M4 with the attached PCIe Native
Expansion Tray.
