The MPI (Message Passing Interface) is a critical standard and technology for high-performance computing, especially for solving large-scale problems in parallel. In the finance field, MPI is mainly used in the calculation of key performance metrics like MPI index. In large-scale optimization, MPI together with GPU acceleration has promising application prospects although not yet prevalent. In this article, we will analyze the role and application of MPI in these two major areas – finance algorithms and large-scale optimization.

MPI Index – A Key Performance Metric in Corporate Finance
The MPI index is a comprehensive measurement of a company’s current period performance. It is composed of 6 factors: RetErn (Retained Earnings), DemPot (Demand Potential), SupPot (Supply Potential), Pdty (Plant Utilization), MktShr (Market Share), and Growth. The MPI index is calculated as the sum of these 6 components. For example, RetErn is measured by RetErn / A / (Period + B) where A and B are constants. DemPot depends on the company’s marketing and R&D expenses compared to the whole industry. SupPot is determined by the company’s factory size over total capacity. Pdty relates to the capacity utilization rate. MktShr depends on the company’s sales volume over total industry volume. Growth is based on the company’s sales growth compared to industry growth. The MPI index provides a quantitative way to evaluate a company’s overall performance.
The Challenge and Potential of Using MPI/GPU for Large-Scale Optimization
Many real-world optimization problems like supply chain optimization and portfolio optimization are large-scale in nature. Traditional methods like simplex algorithms are not efficient enough. GPU can provide massive parallel computing power. But its acceleration effect for sparse problems like Linear Programming (LP) is limited. Some experts argue that large-scale LPs have inherent features of sparsity and sequential optimization steps that do not fully utilize the parallelism of GPUs. However, the combination of MPI and GPU may provide promising solutions. MPI partitions the problem across multiple GPU devices to utilize hybrid parallelism. Each GPU solves a sub-problem in parallel while MPI coordinates between GPUs. More research is still needed into specific parallel optimization algorithms and implementations that can fully exploit this hybrid computing architecture for large-scale sparse optimization.
In summary, MPI has important applications in finance for calculating key metrics like company performance index. It also has huge potential in solving large-scale optimization problems in operations research when combined properly with GPU parallel computing, despite more research being needed in this area.
