Many of the single-user licensed versions of JMP sold previously were 32-bit versions, which can theoretically use up to 2GB of memory.
JMP loads all data into memory for processing, so considering the memory used for calculations such as analysis and display of results in addition to the size of the data table, the data size that can be handled is about several hundred MB. If you are handling data of 500 MB or more, please consider the 64-bit version of JMP or JMP Pro.
All current versions of JMP available for sale are 64-bit.
These products can process large amounts of data, significantly exceeding 2GB, as long as the environment has sufficient memory for the size of the data being handled.
