Technical Depth

Six AI Hardware Disciplines We Master

From GPU cluster architecture to thermal management — we handle every layer of the AI hardware stack so your models get maximum compute at minimum waste.

GPU Cluster Design & Integration

Design, procure, and integrate high-density GPU clusters for large-scale model training — from single-rack A100/H100 nodes to multi-rack DGX SuperPOD configurations. We specify networking topology (InfiniBand vs. Ethernet), NVLink configurations, storage interconnects, and power infrastructure, then oversee physical integration and commissioning with full benchmarking validation.

FPGA-Based Acceleration

Deploy custom inference pipelines on Xilinx Alveo and Intel Stratix FPGAs for workloads demanding deterministic ultra-low latency — HFT scoring, radar signal processing, and sequence-to-sequence models. We implement custom bitstreams with pipelined dataflow architectures that sustain throughput without the jitter of GPU scheduling, achieving sub-microsecond inference for latency-critical applications.

ASIC & Custom Silicon Advisory

Advise on custom AI ASIC pathways for organisations running models at internet scale — evaluating whether NPU-class custom silicon justifies the non-recurring engineering cost, identifying suitable foundry partners, and structuring IP ownership. We also evaluate and benchmark third-party AI accelerators including Graphcore IPUs, Cerebras WSE, and SambaNova to determine fit for specific training and inference workloads.

Inference Server Optimisation

Maximise throughput and minimise latency on inference serving hardware through TensorRT graph optimisation, dynamic batching, quantisation-aware deployment, and multi-model concurrent execution. We profile inference workloads end-to-end — from model loading to response delivery — identifying and eliminating bottlenecks in the preprocessing, inference, and postprocessing pipeline to extract full hardware utilisation.

Memory Hierarchy Optimisation

AI workloads are frequently memory-bandwidth-bound rather than compute-bound — training large transformers hits HBM bandwidth limits long before CUDA core utilisation peaks. We analyse memory access patterns, implement activation checkpointing, gradient compression, and mixed-precision training to fit larger models into available VRAM, reducing the GPU count required for a given model size by 30–50%.

Thermal & Power Management

High-density GPU clusters generate extraordinary heat — a 10-node H100 cluster can draw 80kW. We design thermal management strategies covering airflow optimisation, liquid cooling integration, rack power distribution, and UPS sizing to ensure stable sustained performance without thermal throttling. We also implement DCGM-based power capping policies that balance throughput with data centre PUE targets.

Workload Profiling

Before specifying any hardware, we profile your AI workloads in detail — characterising compute intensity, memory bandwidth requirements, model size, batch processing patterns, and latency constraints. This profiling determines whether your bottleneck is compute, memory bandwidth, or networking — each pointing to different hardware solutions. Getting this wrong means spending on the wrong resource.

  • Training vs. inference workload characterisation
  • Memory bandwidth vs. compute intensity analysis
  • Model size and parallelism strategy assessment
  • Latency, throughput, and cost-per-inference target setting
Step 02 of 05

Hardware Selection & Procurement

Armed with workload profiles, we evaluate hardware candidates against your requirements — benchmarking FLOPS, memory capacity, bandwidth, interconnect speed, and total cost of ownership. We provide objective comparison reports across NVIDIA, AMD, and Intel accelerators, and advise on procurement strategy: direct purchase, leased hardware, or cloud-equivalent alternatives for variable workloads.

  • Multi-vendor evaluation: NVIDIA, AMD Instinct, Intel Gaudi
  • TCO analysis: CapEx vs. cloud-equivalent OpEx
  • Interconnect selection: InfiniBand HDR vs. RoCE Ethernet
  • Procurement negotiation and vendor relationship management
Step 03 of 05

Cluster Setup & Networking

Physical cluster integration requires precise attention to rack layout, power distribution, cable management, and cooling topology. We configure InfiniBand or high-speed Ethernet fabrics for inter-GPU communication, set up NVLink bridges for intra-node connectivity, configure storage interconnects (NVMe-oF or Lustre), and validate network bandwidth meets the all-reduce communication requirements of distributed training workloads.

  • Rack layout, power PDU, and UPS configuration
  • InfiniBand HDR fabric configuration and validation
  • NVLink and NVSwitch topology verification
  • High-performance storage: NVMe-oF, Lustre, GPFS
Step 04 of 05

Software Stack Integration

Hardware without the right software stack delivers a fraction of its theoretical performance. We install and configure CUDA, ROCm, or oneAPI drivers, NCCL for collective communication, Slurm or Kubernetes for job scheduling, and the full ML framework stack — PyTorch, TensorFlow, DeepSpeed, Megatron-LM — verified against your target workloads with reproducible baseline benchmarks before handover.

  • Driver stack: CUDA, ROCm, or Intel oneAPI
  • NCCL / RCCL collective communication configuration
  • Job scheduler: Slurm with GPU partition management
  • Monitoring: DCGM, Prometheus, Grafana dashboards
Step 05 of 05

Benchmarking & Tuning

We validate that the delivered cluster achieves the performance targets set at workload profiling. Running MLPerf training benchmarks and workload-specific throughput tests, we identify underperforming components, tune NCCL collective algorithms for your specific topology, optimise Slurm scheduling policies, and document achievable MFU (model FLOPS utilisation) baselines that give your team predictable performance expectations for production workloads.

  • MLPerf benchmark validation and performance baselining
  • NCCL algorithm tuning for cluster topology
  • Thermal throttle detection and power ceiling calibration
  • MFU (model FLOPS utilisation) documentation per workload class

Real-World Impact

AI Hardware Problems We've Solved

Production AI hardware deployments across sectors — each built to maximise compute utilisation and minimise cost per model.

LLM Training Infrastructure

Enterprise AI

Core Challenge

Training large language models requires tightly coordinated GPU clusters where networking bottlenecks — not compute — are the dominant constraint. Poor InfiniBand configuration or suboptimal NCCL collective settings can reduce effective MFU from 55% to under 30%, doubling training time and cost for the same hardware spend.

Who Benefits

Enterprises building proprietary LLMs for domain-specific applications, AI labs requiring on-premise training infrastructure for data sovereignty, and research institutions that need reproducible, managed GPU cluster environments for long-running pretraining and fine-tuning experiments.

Real-Time Inference Farm

Cloud Provider

Core Challenge

Serving ML inference at scale — hundreds of thousands of requests per second with sub-10ms SLAs — requires hardware configured specifically for inference throughput rather than training, with TensorRT optimised model graphs, multi-model concurrency, and dynamic batching policies that maximise GPU utilisation without violating latency budgets.

Who Benefits

Cloud AI service providers, SaaS companies with embedded ML features, and enterprises running high-QPS AI APIs who need a dedicated inference infrastructure layer that delivers predictable latency SLAs under variable traffic load with cost-efficient hardware utilisation.

Media

Core Challenge

Large-scale video AI — transcription, scene detection, content moderation — requires hardware pipelines that sustain throughput on hours of video content with mixed-precision inference, video decode acceleration, and storage bandwidth that matches GPU processing speed without creating I/O bottlenecks that idle expensive compute.

Who Benefits

Streaming platforms, broadcast media companies, and video content aggregators that process large libraries or live streams and need dedicated AI processing infrastructure capable of handling diverse video formats with consistent throughput and quality-of-service guarantees.

Scientific Simulation Compute

Research

Core Challenge

Scientific AI workloads — molecular dynamics, climate modelling, protein structure prediction — have distinct memory and compute profiles from deep learning, often requiring FP64 precision and massive aggregate memory capacity that standard AI GPU configurations do not address without specific hardware selection and MIG partitioning strategies.

Who Benefits

Research institutions, national laboratories, and pharmaceutical companies running AI-accelerated scientific simulations that need hardware clusters designed for their specific precision, memory, and interconnect requirements — separate from the GPU configurations optimised for commercial AI training.

Frequently Asked

AI Hardware Questions

Answers to the questions infrastructure teams, CIOs, and ML platform engineers ask before starting an AI hardware engagement with Presear Softwares.

Ask Our Hardware Team
GPU vs. FPGA — which is right for my AI workload?
GPUs are the default choice for training and most inference workloads — they offer programmability, a mature software ecosystem (CUDA, TensorRT), and outstanding performance on matrix-heavy operations. FPGAs excel in scenarios requiring deterministic ultra-low latency (sub-microsecond), extremely high energy efficiency for a specific fixed inference pipeline, or in applications where custom data-flow pipelines outperform the SIMT execution model of GPUs. For most enterprises, GPUs are the right answer; we recommend FPGAs only when the latency or power requirements genuinely cannot be met by GPU-based solutions.
How do you size a training cluster for a given model?
Cluster sizing starts with the model parameter count and target training timeline. A 7B parameter LLM trained to production quality on 1T tokens requires roughly 6,000–8,000 H100 GPU-hours. We model GPU memory requirements (accounting for weights, gradients, optimizer states, and activations), determine the minimum per-GPU memory and the parallelism strategy (data, tensor, pipeline), then specify GPU count, interconnect bandwidth, and storage throughput to hit your training timeline within budget. We document assumptions and sensitivities so you can adjust targets if hardware costs shift.
Can you work with our existing hardware rather than replacing it?
Yes — our first recommendation is always to maximise the value of what you have before purchasing new hardware. We profile your existing GPU fleet for utilisation, identify scheduling inefficiencies (idle GPU time between jobs is common), tune NCCL and networking configuration, and often recover 30–50% more effective throughput from existing clusters through software optimisation alone. If the existing hardware genuinely cannot meet your requirements, we provide an objective gap analysis before specifying new procurement.
What networking is needed for a multi-GPU training cluster?
For distributed training, inter-node communication dominates performance — the all-reduce operations that synchronise gradients across GPUs require high-bandwidth, low-latency interconnects. We recommend InfiniBand HDR (200Gb/s) or NDR (400Gb/s) for training clusters above 8 nodes, as RDMA-based collective communication dramatically outperforms standard Ethernet for this pattern. For smaller clusters or inference serving, RoCE (RDMA over Converged Ethernet) on 100GbE provides a cost-effective alternative. Intra-node, NVLink provides 600–900GB/s between GPUs on DGX systems, which we always configure and validate.
How do you manage the thermal load of high-density GPU clusters?
A fully loaded rack of 8 H100s draws up to 32kW — far beyond what standard air-cooled data centre rows can handle. We assess your data centre's cooling capacity first, then design a thermal strategy: direct liquid cooling (DLC) for new high-density deployments, hot-aisle containment optimisation for air-cooled environments, or rear-door heat exchangers as a retrofit option. We also implement DCGM-based power capping that allows the cluster to sustain maximum useful throughput without exceeding thermal envelope, preventing thermal throttling that silently degrades training performance.
