Data set size and computational power evolution. (a) Evolution of multidimensional data sets and their sizes over the last decade. Acronym list: BE, band excitation; SSPFM, switching spectroscopy piezoresponse force microscopy; TR PFM, time resolved piezoresponse force microscopy; BE SSPFM, band excitation piezoresponse force microscopy; TR BE, time resolved band excitation; FORC, first-order reversal curve. (b) Typical processing/acquisition time (smaller value is better) on a laptop, desktop, and cluster for multidimensional data sets. Hardware configurations were assumed as follows: laptop - 4-core processor, 8 GB of RAM, integrated video, and 1 hard drive approximately 1 TB of space; desktop - 12-core processor, 32 GB RAM, dedicated video, 2 hard drives, 4 TB of space; cluster - 10 nodes, each node with 8 processors at 8 cores, 20 GB of RAM, 160 GB storage space.
