Accelerator-optimized machine family

The accelerator-optimized machine family is designed by Google Cloud to deliver the needed performance and efficiency for GPU accelerated workloads such as artificial intelligence (AI), machine learning (ML), and high performance computing (HPC).

The accelerator-optimized machine family is available in the following machine series: A3, A2 and G2. Each machine type within a series has a specific model and number of NVIDIA GPUs attached. You can also attach some GPU models to N1 general-purpose machine types.

The A3 machine series

The A3 machine series has 208 vCPUs, and 1,872 GB of memory. This machine series is optimized for compute and memory intensive, network bound ML training, and HPC workloads.

The A3 machine series also provides the following features:

  • Next generation hardware: each A3 machine type has NVIDIA H100 SXM GPUs attached, which offers 80GB GPU memory per GPU and is ideal for large transformer-based language models, databases, and HPC.

    This machine series is built on the 4th Generation Intel Xeon Scalable processor (Sapphire Rapids) and offers up to 3.3 GHz sustained single-core max turbo frequency.

  • Industry-leading NVLink scale: NVIDIA H100 GPUs provide peak GPU NVLink bandwidth of 450 GB/s, unidirectionally. With all-to-all NVLink topology between 8 GPUs in a system, the aggregate NVLink Bandwidth is up to 7.2 TB/s. These GPUs can be used as a single high performance accelerator with unified memory space to deliver up to 25 petaFLOPS of AI/DL/ML compute power and up to 50 petaFLOPS of inference compute power.

  • Improved computing speed and networking: A3 machine series offers up to 2.5X networking speeds when compared to the previous generation A2 machine series. For more information about networking, see Networking and the A3 machine series.

  • Virtualization optimizations: The Peripheral Component Interconnect Express (PCIe) topology of A3 VMs provides more accurate locality information that workloads can use to optimize data transfers.

    The NVIDIA H100 GPUs also expose Function Level Reset (FLR) for graceful recovery from failures and atomic operations support for concurrency improvements in certain scenarios.

  • Storage: 6,000 GiB of Local SSD is automatically added to VMs created by using any of the A3 machine types. Local SSD can be used for fast scratch disks or for feeding data into the GPUs while preventing I/O bottlenecks.

    You can also attach up to 257 TiB of Persistent Disk storage to the machine types in these series for applications that require higher storage performance.

  • Compact placement policy support: provides you with more control over the physical placement of your VMs within data centers. This enables lower-latency and higher bandwidth for VM placement within a single availability zone. For more information, see About compact placement policies.

Networking and the A3 machine series

A3 machine series offer up to 2.5X improvement in computing speed compared to A2 machine series. The a3-highgpu-8g machine type provides 10x network bandwidth when compared to previous generation A2 machine types. The a3-megagpu-8g machine type provides 2x network bandwidth when compared to a3-highgpu-8g and 20x network bandwidth compared to A2 machine types.

  • Single NIC A3 VMs: For A3 VMs with 1 to 4 GPUs attached, only a single physical network interface card (NIC) is available.
  • Multi-NIC A3 VMs: For A3 VMs with 8 GPUS attached, multiple physical NICs are available. For these A3 machine types the NICs are arranged as follows on a Peripheral Component Interconnect Express (PCIe) bus:
    • For the A3 Mega machine type: a NIC arrangement of 8+1 is available. With this arrangement, 8 NICs share the same PCIe bus, and 1 NIC resides on a separate PCIe bus.
    • For the A3 High machine type: a NIC arrangement of 4+1 is available. With this arrangement, 4 NICs share the same PCIe bus, and 1 NIC resides on a separate PCIe bus.
    • For the A3 Edge machine type machine type: a NIC arrangement of 4+1 is available. With this arrangement, 4 NICs share the same PCIe bus, and 1 NIC resides on a separate PCIe bus. These 5 NICs provide a total network bandwidth of 400 Gbps for each VM.

    NICs that share the same PCIe bus, have a non-uniform memory access (NUMA) alignment of one NIC per two NVIDIA H100 80GB GPUs. These NICs are ideal for dedicated high bandwidth GPU to GPU communication. The physical NIC that resides on a separate PCIe bus is ideal for other networking needs.

Network protocols

By leveraging GPUDirect-TCPX, the a3-highgpu-8g machine type achieves much higher throughput between VMs in a cluster when compared to the A2 or G2 accelerator-optimized machine types.
  • For the A3 Mega machine types, GPUDirect-TCPXO further improves on GPUDirect-TCPX by offloading TCP protocol processing to the SmartNIC's ACC cores. By leveraging GPUDirect-TCPXO, the a3-megagpu-8g machine type doubles the network bandwidth when compared to the a3-highgpu-8g machine type.

  • Improved Computing speed: the attached NVIDIA A100 GPUs offer up to 10x improvements in computing speed when compared to previous generation NVIDIA V100 GPUs.

    With the A2 machine series, you can get up to 100 Gbps network bandwidth.

This enables lower-latency and higher bandwidth for VM placement within a single availability zone. For more information, see Reduce latency by using compact placement policies.
