1Power
If high-performance computing clusters are used to perform molecular dynamics simulations, then simulation accuracy and computational power are improved, but device complexity and cost increase
Solution Approach 1:
The patent divides the molecular dynamics simulation workload into multiple partitions, each handled by a separate processor. This segmentation allows the system to achieve high computational power through parallel processing while reducing the complexity of any single computational node, as each processor handles only a subset of the simulation workload.
Solution Approach 2:
The patent employs a universal processor architecture that can execute different types of simulations on the same hardware platform. The system uses a standardized set of processors that can be configured for various molecular dynamics tasks, eliminating the need for specialized expensive hardware for each simulation type and reducing overall system complexity.
2Measurement precision
If high-performance computing clusters are used to perform molecular dynamics simulations, then simulation accuracy is improved, but cost increases
Solution Approach 1:
By segmenting the simulation into partitions that can be processed independently on standard processors, the system achieves high simulation accuracy through parallel computation without requiring expensive specialized hardware. Each partition can be processed by affordable processors, reducing overall system cost while maintaining accuracy.
Solution Approach 2:
The patent uses multiple copies of the same processor architecture to handle different simulation partitions. Instead of requiring expensive specialized hardware, the system replicates standard processor units that can all perform the required computations, significantly reducing system cost while maintaining simulation accuracy through parallel processing.
3Measurement precision
If computational complexity of localized models increases, then simulation accuracy is improved, but processing time increases
Solution Approach 1:
The patent segments the molecular structure into multiple regions, each processed by a separate processor with a localized model. This segmentation allows high-complexity accurate models to be applied to each region independently, improving overall simulation accuracy while reducing processing time through parallel execution, as each processor works on a smaller subset of the molecular structure.
Solution Approach 2:
The patent applies localized models with appropriate computational complexity to each partition based on the specific requirements of that region. Rather than uniformly applying high-complexity models throughout, the system uses partial action by applying high complexity only where necessary, improving accuracy in critical regions while reducing overall processing time by using simpler models where acceptable.
4Productivity
If more processors are used to parallelize simulations, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent segments the simulation workload into partitions that can be distributed across multiple processors. This segmentation enables parallel processing and improves simulation speed while keeping each individual processor relatively simple, as each handles only a portion of the workload. The system complexity is managed through the partitioning strategy rather than requiring complex hardware architecture.
Solution Approach 2:
The patent assigns different levels of computational complexity to different processors based on the specific requirements of each partition. Local quality is applied by matching the model complexity to the simulation requirements of each region, allowing the system to scale productivity by adding processors while maintaining manageable complexity through differentiated processing requirements.
