Rotating Drum Benchmark (phasicFlow v-1.0)

Overview

This benchmark compares the performance of phasicFlow with a well-stablished commercial DEM software for simulating a rotating drum with varying particle counts (250k to 8M particles). The benchmark measures both computational efficiency and memory usage across different hardware configurations.

Simulation Setup

Hardware Specifications

Table 1. Hardware specifications used for benchmarking.
System CPU GPU Operating System
Laptop Intel i9-13900HX 2.2 GHz NVIDIA GeForce RTX 4050Ti 6G Windows 11 24H2
Workstation Intel Xeon 4210 2.2 GHz NVIDIA RTX A4000 16G Ubuntu 22.04

Simulation Parameters

Table 2. Parameters for rotating drum simulations.
Case Particle Diameter Particle Count Drum Length Drum Radius
250k 6 mm 250,000 0.8 m 0.2 m
500k 5 mm 500,000 0.8 m 0.2 m
1M 4 mm 1,000,000 0.8 m 0.2 m
2M 3 mm 2,000,000 1.2 m 0.2 m
4M 3 mm 4,000,000 1.6 m 0.2 m
8M 2 mm 8,000,000 1.6 m 0.2 m

The time step for all simulations was set to 1.0e-5 seconds and the simulation ran for 4 seconds.

Performance Comparison

Execution Time

Table 3. Total calculation time (minutes) for different configurations.
Software 250k 500k 1M 2M 4M 8M
phasicFlow-4050Ti 54 min 111 min 216 min 432 min - -
Commercial DEM-4050Ti 68 min 136 min 275 min 570 min - -
phasicFlow-A4000 38 min 73 min 146 min 293 min 589 min 1188 min

The execution time scales linearly with particle count. phasicFlow demonstrates approximately:

  • 20% faster calculation than the well-established commercial DEM software on the same hardware
  • 30% performance improvement when using the NVIDIA RTX A4000 compared to the RTX 4050Ti

Memory Usage

Table 4. Memory consumption for different configurations.
Software 250k 500k 1M 2M 4M 8M
phasicFlow-4050Ti 252 MB 412 MB 710 MB 1292 MB - -
Commercial DEM-4050Ti 485 MB 897 MB 1525 MB 2724 MB - -
phasicFlow-A4000 344 MB 480 MB 802 MB 1386 MB 2590 MB 4966 MB

Memory efficiency comparison:

  • phasicFlow uses approximately 0.7 GB of memory per million particles
  • Commercial DEM software uses approximately 1.2 GB of memory per million particles
  • phasicFlow shows ~42% lower memory consumption compared to the commercial alternative
  • The memory usage scales linearly with particle count in both software packages. But due to memory limitations on GPUs, it is possible to run larger simulation on GPUs with phasicFlow.
