+## **PhasicFlow: High-Performance Discrete Element Method Simulations**
 
-**PhasicFlow** is a parallel C++ code for performing DEM simulations. It can run on shared-memory multi-core computational units such as multi-core CPUs or GPUs (for now it works on CUDA-enabled GPUs). The parallelization method mainly relies on loop-level parallelization on a shared-memory computational unit. You can build and run PhasicFlow in serial mode on regular PCs, in parallel mode for multi-core CPUs, or build it for a GPU device to off-load computations to a GPU. In its current statues you can simulate millions of particles (up to 80M particles tested) on a single desktop computer. You can see the [performance tests of PhasicFlow](https://github.com/PhasicFlow/phasicFlow/wiki/Performance-of-phasicFlow) in the wiki page.
+PhasicFlow is a robust, open-source C++ framework designed for the efficient simulation of granular materials using the Discrete Element Method (DEM). Leveraging parallel computing paradigms, PhasicFlow is capable of executing simulations on shared-memory multi-core architectures, including CPUs and NVIDIA GPUs (CUDA-enabled). The core parallelization strategy focuses on loop-level parallelism, enabling significant performance gains on modern hardware. Users can seamlessly transition between serial execution on standard PCs, parallel execution on multi-core CPUs (OpenMP), and accelerated simulations on GPUs. Currently, PhasicFlow supports simulations involving up to 80 million particles on a single desktop workstation. Detailed performance benchmarks are available on the [PhasicFlow Wiki](https://github.com/PhasicFlow/phasicFlow/wiki/Performance-of-phasicFlow).
 
-**MPI** parallelization with dynamic load balancing is under development. With this level of parallelization, PhasicFlow can leverage the computational power of **multi-gpu** workstations or clusters with distributed memory CPUs. 
+**Scalable Parallelism: MPI Integration**
-In summary PhasicFlow can have 6 execution modes:
-1. Serial on a single CPU core,
-2. Parallel on a multi-core computer/node (using OpenMP),
-3. Parallel on an nvidia-GPU (using Cuda),
-4. Parallel on distributed memory workstation (Using MPI)
-5. Parallel on distributed memory workstations with multi-core nodes (using MPI+OpenMP)
-6. Parallel on workstations with multiple GPUs (using MPI+Cuda).
-## How to build?
-You can build PhasicFlow for CPU and GPU executions. The latest release of PhasicFlow is v-0.1. [Here is a complete step-by-step procedure for building phasicFlow-v-0.1.](https://github.com/PhasicFlow/phasicFlow/wiki/How-to-Build-PhasicFlow).
 
-## Online code documentation
+Ongoing development includes the integration of MPI-based parallelization with dynamic load balancing. This enhancement will extend PhasicFlow's capabilities to distributed memory environments, such as multi-GPU workstations and high-performance computing clusters. Upon completion, PhasicFlow will offer six distinct execution modes:
-You can find a full documentation of the code, its features, and other related materials on [online documentation of the code](https://phasicflow.github.io/phasicFlow/)
 
-## How to use PhasicFlow?
+1.  **Serial Execution:** Single-core CPU.
-You can navigate into [tutorials folder](./tutorials) in the phasicFlow folder to see some simulation case setups. If you need more detailed discription, visit our [wiki page tutorials](https://github.com/PhasicFlow/phasicFlow/wiki/Tutorials).  
+2.  **Shared-Memory Parallelism:** Multi-core CPU (OpenMP).
+3.  **GPU Acceleration:** NVIDIA GPU (CUDA).
+4.  **Distributed-Memory Parallelism:** MPI.
+5.  **Hybrid Parallelism:** MPI + OpenMP.
+6.  **Multi-GPU Parallelism:** MPI + CUDA.

+## **Dependencies**
+
+PhasicFlow relies on the following external libraries:
+
+* **Kokkos:** A community-led performance portability ecosystem within the Linux Foundation's High-Performance Software Foundation (HPSF). ([https://github.com/kokkos/kokkos](https://github.com/kokkos/kokkos))
+* **CLI11 1.8:** A command-line interface parser developed by the University of Cincinnati. ([https://github.com/CLIUtils/CLI11](https://github.com/CLIUtils/CLI11))

+# 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.

+## Performance Comparison
+
+### Execution Time

+    Table 3. Total calculation time (minutes) for different configurations.
+</div>
+
+|     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

+| 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.
