terradev-cli 3.7.1

Cross-cloud GPU provisioning with automatic CUDA Graph optimization, NUMA-aware topology optimization, vLLM auto-optimization, and Terraform-powered parallel provisioning

Terradev CLI v3.7.1

Compare GPU prices across 19 clouds. Provision the cheapest one in one command. Automatic CUDA Graph optimization included.

🚀 What's New in v3.7.1

🧠 CUDA Graph Optimization with NUMA Awareness

Revolutionary passive CUDA Graph optimization that automatically analyzes and optimizes GPU topology for maximum graph performance:

# Automatic CUDA Graph optimization - no configuration needed
terradev provision -g H100 -n 4

# NUMA-aware endpoint selection happens automatically
# CUDA Graph compatibility is detected passively
# Warm pool prioritizes graph-compatible models

Performance Gains:

• 2-5x speedup for CUDA Graph workloads with optimal NUMA topology
• 30-50% bandwidth penalty eliminated through automatic GPU/NIC alignment
• Zero configuration - everything runs passively in the background
• Model-aware optimization - different strategies for transformers vs MoE models

� NUMA Topology Intelligence

• PIX (Same PCIe Switch): Optimal for CUDA Graphs (1.0 score)
• PXB (Same Root Complex): Very good (0.8 score)
• PHB (Same NUMA Node): Good (0.6 score)
• SYS (Cross-Socket): Poor for graphs (0.3 score)

📊 Model-Specific Optimization

• Transformers: Highest priority (0.9 base score) - benefit most from graphs
• CNNs: Moderate priority (0.7 base score) - benefit moderately
• MoE Models: Lower priority (0.4 base score) - dynamic routing challenges
• Auto-detection: Model types identified automatically from model IDs

🔄 Background Optimization

• Passive Analysis: Runs automatically every 5 minutes
• Warm Pool Enhancement: CUDA Graph models get higher priority
• Endpoint Selection: Routes to NUMA-optimal endpoints automatically
• Performance Tracking: Monitors graph capture time and replay speedup

📋 Complete Tutorial

Step 1: Install Terradev

pip install terradev-cli

For all cloud provider SDKs and ML integrations:

pip install terradev-cli[all]

Verify and list commands:

terradev --help

Step 2: Configure Your First Cloud Provider

Terradev supports 19 GPU cloud providers. Start with one, RunPod is the fastest to set up:

terradev setup runpod --quick

This shows you where to get your API key. Then configure it:

terradev configure --provider runpod

Paste your API key when prompted. It's stored locally at ~/.terradev/credentials.json, never sent to a Terradev server. Add more providers later:

terradev configure --provider vastai
terradev configure --provider lambda_labs
terradev configure --provider aws

The more providers you configure, the better your price coverage.

Step 3: Get Real-Time GPU Prices

Check pricing across every provider you've configured:

terradev quote -g A100

Output is a table sorted cheapest-first: price/hour, provider, region, spot vs. on-demand. Try different GPUs:

terradev quote -g H100
terradev quote -g L40S
terradev quote -g RTX4090

Step 4: Provision

Most clouds hand you GPUs with suboptimal topology by default. Your GPU and NIC end up on different NUMA nodes, RDMA is disabled, and the kubelet Topology Manager is set to none. That's a 30-50% bandwidth penalty on every distributed operation and you'll never see it in nvidia-smi.

When you provision through Terradev, topology optimization is automatic:

terradev provision -g H100 -n 4 --parallel 6

What happens behind the scenes:

• NUMA alignment — GPU and NIC forced to the same NUMA node
• GPUDirect RDMA — nvidia_peermem loaded, zero-copy GPU-to-GPU transfers
• CPU pinning — static CPU manager policy, no core migration
• SR-IOV — virtual functions created per GPU for isolated RDMA paths
• NCCL tuning — InfiniBand enabled, GDR_LEVEL=PIX, GDR_READ=1

You don't configure any of this. It's applied automatically.

To preview the plan without launching:

terradev provision -g A100 -n 2 --dry-run

To set a price ceiling:

terradev provision -g A100 --max-price 2.50

Step 5: Run a Workload

Option A — Run a command on your provisioned instance:

terradev execute -i <instance-id> -c "nvidia-smi"
terradev execute -i <instance-id> -c "python train.py"

Option B — One command that provisions, deploys a container, and runs:

terradev run --gpu A100 --image pytorch/pytorch:latest -c "python train.py"

Option C — Keep an inference server alive:

terradev run --gpu H100 --image vllm/vllm-openai:latest --keep-alive --port 8000

Step 6: Manage Your Instances

# See all running instances and current cost
terradev status --live

# Stop (keeps allocation)
terradev manage -i <instance-id> -a stop

# Restart
terradev manage -i <instance-id> -a start

# Terminate and release
terradev manage -i <instance-id> -a terminate

Step 7: Track Costs and Find Savings

# View spend over the last 30 days
terradev analytics --days 30

# Find cheaper alternatives for running instances
terradev optimize

Step 8: Distributed Training Pipeline

Now that your nodes have correct topology, distributed training actually runs at full bandwidth:

# Validate GPUs, NCCL, RDMA, and drivers before launching
terradev preflight

# Launch training on the nodes you just provisioned
terradev train --script train.py --from-provision latest

# Watch GPU utilization and cost in real time
terradev monitor --job my-job

# Check status
terradev train-status

# Manage checkpoints
terradev checkpoint list --job my-job

The --from-provision latest flag auto-resolves IPs from your last provision command. Supports torchrun, DeepSpeed, Accelerate, and Megatron.

Step 9: Optimize vLLM Inference (The 6 Knobs)

If you're serving a model with vLLM, there are 6 settings most teams leave at defaults — each one costs throughput:

Knob	Default	Optimized	Impact
max-num-batched-tokens	2048	16384	8x throughput
gpu-memory-utilization	0.90	0.95	5% more VRAM
max-num-seqs	256/1024	512-2048	Prevent queuing
enable-prefix-caching	OFF	ON	Free throughput win
enable-chunked-prefill	OFF	ON	Better prefill
CPU Cores	2 + #GPUs	Optimized	Prevent starvation

Auto-tune all six from your workload profile:

terradev vllm auto-optimize -s workload.json -m meta-llama/Llama-2-7b-hf -g 4

Or analyze a running server:

terradev vllm analyze -e http://localhost:8000

Benchmark:

terradev vllm benchmark -e http://localhost:8000 -c 10

Step 10: Deploy a MoE Model with Auto-Applied Optimizations

For large Mixture-of-Experts models (GLM-5, Qwen 3.5, DeepSeek V4), Terradev's MoE templates include every optimization auto-applied — KV cache offloading, speculative decoding, sleep mode, expert load balancing:

terradev provision --task clusters/moe-template/task.yaml \
  --set model_id=Qwen/Qwen3.5-397B-A17B

Or a smaller model:

terradev provision --task clusters/moe-template/task.yaml \
  --set model_id=Qwen/Qwen3.5-122B-A10B --set tp_size=4 --set gpu_count=4

What's auto-applied (no flags needed):

• KV cache offloading — spills to CPU DRAM, up to 9x throughput
• MTP speculative decoding — up to 2.8x faster generation
• Sleep mode — idle models hibernate to CPU RAM, 18-200x faster than cold restart
• Expert load balancing — rebalances routing at runtime
• LMCache — distributes KV cache across instances via Redis

Step 11: Disaggregated Prefill/Decode (Advanced)

This separates inference into two GPU pools optimized for each phase:

• Prefill (compute-bound) — processes input prompt, wants high FLOPS
• Decode (memory-bound) — generates tokens, wants high HBM bandwidth

The KV cache transfers between them via NIXL — zero-copy GPU-to-GPU over RDMA. This is why getting the NUMA topology right in Step 4 matters: NIXL only runs at full speed when the GPU and NIC share a PCIe switch.

terradev ml ray --deploy-pd \
  --model zai-org/GLM-5-FP8 \
  --prefill-tp 8 --decode-tp 1 --decode-dp 24

Terradev's inference router automatically uses sticky routing. Once a prefill GPU hands off a KV cache to a decode GPU, future requests with the same prefix go to that same decode GPU, avoiding redundant transfers.

Step 12: Create a Kubernetes GPU Cluster

For production, create a topology-optimized K8s cluster:

terradev k8s create my-cluster --gpu H100 --count 8 --prefer-spot

This auto-configures Karpenter NodePools with NUMA-aligned kubelet Topology Manager, GPUDirect RDMA, and PCIe locality enforcement.

# List clusters
terradev k8s list

# Get cluster info
terradev k8s info my-cluster

# Tear down
terradev k8s destroy my-cluster

Why This Order Matters

Each step builds on the one before it:

• Step 4: NUMA / RDMA / SR-IOV topology ← foundation
• Step 8: Distributed training at full BW ← depends on topology
• Step 9: vLLM knob tuning ← depends on correct memory layout
• Step 10: KV cache offloading + sleep mode ← depends on CPU bus not saturated
• Step 11: Disaggregated P/D ← depends on RDMA for KV transfer

If the provisioning layer is wrong, every optimization above it underperforms. A disaggregated P/D setup with a cross-NUMA KV transfer is slower than a monolithic setup with correct topology.

Terradev handles the foundation automatically so the rest of the stack works the way it's supposed to.
