研究目的
To accelerate SMLM data processing via a parallelized implementation of ThunderSTORM on a high-performance computing (HPC) cluster.
研究成果
The parallelized implementation of ThunderSTORM on an HPC cluster significantly accelerates SMLM data processing, with the speed advantage scalable by accessing more HPC resources. This approach is adaptable to a wide range of SMLM software and is particularly beneficial for high throughput SMLM applications.
研究不足
The approach requires access to HPC resources, and the speed advantage may be offset by the overheads associated with transferring data to the HPC cluster, depending on the local network infrastructure. Additionally, the method does not utilize GPU processing, which could offer further speed enhancements.
The methodology involves parallelizing the SMLM data processing using ThunderSTORM on an HPC cluster. The approach includes dividing the SMLM data into subsets for parallel processing, utilizing the Bio-Formats library for data preparation, and implementing two workflows for SMLM processing: 'Parallel mode' for rapid analysis of large data sets and 'Batch mode' for automated processing of multiple data sets. The performance of this approach is quantified by comparing processing times on a four-node HPC cluster with those on a high-specification desktop workstation.
