# EPYC Cluster Setup and Access Guide
## Overview
Two AMD EPYC 16-core servers running distributed parameter exploration for trading bot optimization.
**Total Capacity:** 64 cores processing 12M parameter combinations
---
## Server Access
### Worker1: pve-nu-monitor01 (Direct SSH)
```bash
# Direct access from srvdocker02
ssh root@10.10.254.106
# Specs
- Hostname: pve-nu-monitor01
- IP: 10.10.254.106
- CPU: AMD EPYC 7282 16-Core Processor (32 cores with hyperthreading)
- Location: /home/comprehensive_sweep/backtester/
```
### Worker2: bd-host01 (SSH Hop Required)
```bash
# Access via 2-hop through worker1
ssh root@10.10.254.106 "ssh root@10.20.254.100 'COMMAND'"
# SCP via 2-hop
scp FILE root@10.10.254.106:/tmp/
ssh root@10.10.254.106 "scp /tmp/FILE root@10.20.254.100:/path/"
# Specs
- Hostname: bd-host01
- IP: 10.20.254.100 (only accessible from worker1)
- CPU: AMD EPYC 7282 16-Core Processor (32 cores with hyperthreading)
- Location: /home/backtest_dual/backtest/
```
### Coordinator: srvdocker02 (Local)
```bash
# Running on trading bot server
cd /home/icke/traderv4/cluster/
# Specs
- Hostname: srvdocker02
- Role: Orchestrates distributed sweep, hosts trading bot
- Database: SQLite at /home/icke/traderv4/cluster/exploration.db
```
---

### Coordinator Structure
```
/home/icke/traderv4/cluster/
├── distributed_coordinator.py # Main orchestrator
├── distributed_worker.py # Worker script (template for worker1)
├── distributed_worker_bd_clean.py # Worker script (template for worker2)
├── monitor_bd_host01.sh # Monitoring script
├── exploration.db # Chunk tracking database
└── chunk_*.json # Chunk specifications
```
---
## How It Works
### 1. Coordinator (srvdocker02)
- Splits 12M parameter space into chunks (10,000 combos each)
- Stores chunk assignments in SQLite database
- Deploys chunk specs and worker scripts via SSH/SCP
- Starts workers via SSH with nohup (background execution)
- Monitors chunk completion and collects results
### 2. Workers (EPYCs)
- Each processes assigned chunks independently
- Uses multiprocessing.Pool with **70% CPU limit** (22 cores)
- Outputs results to CSV files in their workspace
- Logs progress to /tmp/v9_chunk_XXXXXX.log
### 3. Results Collection
- Workers save to: `chunk_v9_chunk_XXXXXX_results.csv`
- Coordinator can fetch results via SCP
- Trading bot API endpoint serves results to web UI
---
## Common Operations
### Start Distributed Sweep
```bash
cd /home/icke/traderv4/cluster/
# Clear old chunks and start fresh
rm -f exploration.db
nohup python3 distributed_coordinator.py > sweep.log 2>&1 &
# Monitor progress
tail -f sweep.log
```
### Monitor Worker Status
```bash
# Check worker1
ssh root@10.10.254.106 "top -bn1 | grep Cpu && ps aux | grep distributed_worker | wc -l"
# Check worker2 (via hop)
ssh root@10.10.254.106 "ssh root@10.20.254.100 'top -bn1 | grep Cpu && ps aux | grep distributed_worker | wc -l'"
# Use monitoring script
/home/icke/traderv4/cluster/monitor_bd_host01.sh
```
### Fetch Results
```bash
# Worker1 results
scp root@10.10.254.106:/home/comprehensive_sweep/backtester/chunk_*_results.csv ./
# Worker2 results (2-hop)
ssh root@10.10.254.106 "scp root@10.20.254.100:/home/backtest_dual/backtest/chunk_*_results.csv /tmp/"
scp root@10.10.254.106:/tmp/chunk_*_results.csv ./
```
### View Results in Web UI
```bash
# Access cluster status page
http://localhost:3001/cluster
# or
https://tradervone.v4.dedyn.io/cluster
# Shows:
- Real-time CPU usage and worker status
- Exploration progress
- Top 5 strategies with parameters
- AI recommendations for next actions
```
### Kill All Workers
```bash
# Kill worker1
ssh root@10.10.254.106 "pkill -f distributed_worker"
# Kill worker2
ssh root@10.10.254.106 "ssh root@10.20.254.100 'pkill -f distributed_worker'"
# Kill coordinator
pkill -f distributed_coordinator
```
---
## CPU Limit Configuration
### Why 70%?
- Prevents server overload
- Leaves headroom for system operations
- Balances throughput vs stability
### Implementation
Both worker scripts limit CPU via multiprocessing.Pool:
```python
# In distributed_worker.py and distributed_worker_bd_clean.py
max_workers = max(1, int(num_workers * 0.7)) # 70% of 32 cores = 22
with mp.Pool(processes=max_workers) as pool:
# Processing happens here
```
**Expected CPU Usage:** 67-72% user time on each EPYC
---
## Troubleshooting
### Worker Not Starting
```bash
# Check worker logs
ssh root@10.10.254.106 "tail -100 /tmp/v9_chunk_*.log"
ssh root@10.10.254.106 "ssh root@10.20.254.100 'tail -100 /tmp/v9_chunk_*.log'"
# Common issues:
# 1. Import errors - check sys.path and module structure
# 2. Data file missing - verify solusdt_5m*.csv exists
# 3. Virtual env activation failed - check .venv/bin/activate path
```
### SSH Hop Issues (Worker2)
```bash
# Test 2-hop connectivity
ssh root@10.10.254.106 "ssh root@10.20.254.100 'echo SUCCESS'"
# If fails, check:
# - Worker1 can reach worker2: ssh root@10.10.254.106 "ping -c 3 10.20.254.100"
# - SSH keys are set up between worker1 and worker2
```
### Python Bytecode Cache Issues
```bash
# Clear .pyc files if code changes don't take effect
find /home/icke/traderv4/cluster -name "*.pyc" -delete
find /home/icke/traderv4/cluster -name "__pycache__" -type d -exec rm -rf {} +
```
### Database Lock Issues
```bash
# If coordinator fails to start due to DB lock
cd /home/icke/traderv4/cluster/
pkill -f distributed_coordinator # Kill any running coordinators
rm -f exploration.db # Delete database
# Then restart coordinator
```

## Files Created/Modified
**New Files:**
- `cluster/distributed_coordinator.py` - Main orchestrator (510 lines)
- `cluster/distributed_worker.py` - Worker script for worker1 (271 lines)
- `cluster/distributed_worker_bd_clean.py` - Worker script for worker2 (275 lines)
- `cluster/monitor_bd_host01.sh` - Monitoring script
- `app/api/cluster/status/route.ts` - API endpoint for web UI (274 lines)
- `app/cluster/page.tsx` - Web UI page (258 lines)
- `cluster/CLUSTER_SETUP.md` - This documentation
**Modified Files:**
- Docker rebuilt with new API endpoint and cluster page
---
## Next Steps
1. **Monitor first chunk completion** (~10-30 min)
2. **Analyze top strategies** via web UI at `/cluster`
3. **Scale to full sweep** - all 1,195 chunks across both EPYCs
4. **Implement best parameters** in production trading bot
5. **Iterate** - refine grid based on results
---
## Notes
- **70% CPU limit ensures system stability** while maximizing throughput
- **Coordinator is stateless** - stores all state in SQLite, can restart anytime
- **Workers are autonomous** - process chunks independently, no coordination needed
- **Results are immutable** - each chunk produces one CSV, never overwritten
- **Web UI provides actionable insights** - no manual CSV analysis needed
**Last Updated:** November 30, 2025

"""
Distributed Continuous Optimization Coordinator
Extends comprehensive_sweep.py to distribute massive parameter grids
across 2 EPYC servers (64 cores total) for 24/7 strategy discovery.
Architecture:
1. Master generates parameter grid (millions of combinations)
2. Splits into chunks (~10,000 combos per chunk)
3. Distributes chunks to workers via SSH
4. Workers run modified comprehensive_sweep on their chunk
5. Master aggregates results, identifies top performers
6. Master generates next exploration batch (nearby good configs)
7. Repeat forever - continuous improvement
Integration with Existing System:
- Uses simulator.py and MoneyLineInputs from /home/comprehensive_sweep/backtester/
- Preserves comprehensive_sweep.py output format (CSV with 14 params)
- Works with existing .venv and data files on EPYC
- Backwards compatible - can still run comprehensive_sweep.py standalone
