Server Description

An accelerator-optimized platform featuring four dedicated GPUs and high-capacity memory for demanding parallel processing and large language model inference.

GPU AcceleratedMemory OptimizedStorage & Database

Google Cloud Platform a2-ultragpu-4g is an accelerator-optimized server featuring four NVIDIA Ampere A100 GPUs with 320 GB of total VRAM, 48 vCPUs on an Intel Xeon x86_64 architecture, 680.0 GB of RAM, and 1608 GB of NVMe SSD storage. While single-core CPU benchmarks place the instance in the bottom 25%, its multi-core and memory bandwidth performance sit in the middle 50%. The server achieves top-tier status in LLM inference prompt processing and text generation for medium and large models. This hardware profile is optimized for GPU-heavy workloads, trading off single-threaded CPU speed for massive parallel processing capabilities. It is designed for deep learning, large language model inference, and complex data science workloads.

Workload Profiles

1.4Score
Precomputed compound score for Cache Intensive workloads. A weighted average (geometric mean) of benchmark scores compared to their medians: score = ∏ (x_i / m_i)^(w_i / Σw). The score of 1.0 represents a synthetic baseline server with the median performance of each component benchmark; 0.5 means roughly half the performance; and 2.0 means twice the performance of that reference profile. Component weights: 50% Redis RPS (pipeline=1, SET), 20% Redis RPS (pipeline=16, SET), 10% PassMark Memory Mark (composite), 10% Memory bandwidth (read, 16 MB ~ L3), 10% PassMark single-thread CPU. Rationale for component selection: In-memory key-value store workload, mixing direct Redis performance metrics with memory speed and latency benchmarks, and single-core CPU performance profiles.
