CS621 Assignment 1 Solution Fall 2025 | Parallel Processing | SIMD vs MIMD

In this video, you’ll learn how to solve CS621 Assignment 1 (Fall 2025) step-by-step.
The problem models an image-filtering workload across SIMD and MIMD architectures to calculate:

Total Execution Time

Throughput (streams per µs)

Performance Analysis considering synchronization and communication overheads

💡 Key Concepts Covered

✅ SIMD (Single Instruction Multiple Data) Architecture
✅ MIMD (Multiple Instruction Multiple Data) Architecture
✅ Synchronization vs Communication overheads
✅ Execution time and throughput calculations
✅ Parallel workload modeling (CS621-style analysis)

🧑‍💻 Assignment Summary

Problem:
16 independent data streams, 50 operations each (0.2 µs per operation)

Architecture A (SIMD):
8 processors, synchronous, 2 µs sync delay per batch

Architecture B (MIMD):
8 processors, asynchronous, 10 µs communication delay per processor

Results:

Parameter SIMD MIMD
Total Execution Time 24 µs 30 µs
Throughput 0.6667 streams/µs 0.5333 streams/µs
Winner ✅ SIMD performs better
