Interactive visualizations of actor simulations with virtual time
These reports demonstrate the visualization capabilities of GenServerVirtualTime, a library for testing time-based GenServers and simulating actor systems with virtual time. All simulations run in milliseconds but simulate seconds or minutes of virtual time.
NEW! These reports visualize actor system topology using Mermaid flowcharts with embedded statistics. They show message flow, activity levels, and performance metrics.
Multi-stage data processing pipeline with message forwarding and statistics.
View Report →Publisher broadcasting events to multiple subscribers with message rates.
View Report →Load balancer distributing work to multiple workers with result collection.
View Report →Simulation that stops when goal is achieved, showing exact termination point.
View Report →7 actors randomly sending :hi messages with fixed seed for reproducible results.
View Report →Token passing ring with 7 actors, complete circular message flow.
View Report →7 VirtualTimeGenServer actors with random delays 200-300ms, real module implementation.
View Report →7 actors in full mesh topology sending random :hi messages with reproducible seed.
View Report →Demonstrates quiescence termination - sender emits 10 messages, receiver batches and replies once.
View Report →These diagrams show message-by-message interaction between actors over time. Perfect for understanding communication patterns and debugging.
Basic client-server interaction with request and response messages.
View Diagram →Multi-stage authentication flow: API → Auth → Database → Response.
View Diagram →Demonstrates synchronous calls and asynchronous casts with different arrow styles.
View Diagram →Shows virtual time progression with timestamp annotations.
View Diagram →Classic concurrency problem demonstrating deadlock-free message passing with various table sizes and termination conditions.
Shows 2 philosophers both eating - watch for "I'm full!" from each!
View Diagram →Classic 5-philosopher problem solved - flowchart showing all philosophers successfully eating at least once.
View Report →Demonstrates dramatic virtual time speedup with 10ms thinking delays - watch the performance metrics!
View Report →Visual actor topology with different shapes for sources, sinks, and processors
Message counts and rates displayed directly on diagram nodes
Color-coded nodes based on message activity levels
Support for TB, LR, RL, and BT flowchart directions
Visual indicators when simulations stop upon achieving goals
Simulate hours of behavior in milliseconds with precise control
Virtual time speedup calculations and real-time comparisons
Sequence diagrams showing every message exchange
