Speed can also be important when managing large datasets. Taken at the median, estimation commands run 1.8 times faster on 2 cores, 3.1 times faster on 4 cores, and 4.2 times faster on 8 cores. Some estimation commands can be parallelized more than others. A few of Stata’s estimation procedures, including linear regression, are nearly perfectly parallelized, meaning they run twice as fast on two cores, four times as fast on four cores, eight times as fast on eight cores, and so on. Speed is often most crucial when performing computationally intense estimation procedures. Stata/MP supports up to 64 cores/processors. Stata/MP runs even faster on multiprocessor servers. Stata/MP lets you analyze data in one-half to two-thirds the time compared with Stata/SE on inexpensive dual-core laptops and in one-quarter to one-half the time on quad-core desktops and laptops.
For short term 'evaluation' or for long term use? If short term, then you can contact Stata corp (visit their website) for an 30 days evaluation version of Stata 14. Then, in Stata type edit in the command line to open the data editor.
