Almost every computer can take advantage of the advanced multiprocessing capabilities of Stata/MP. Stata/MP is a version of Stata/SE that runs on multicore and multiprocessor computers. Stata/MP provides the most extensive support for multicore computers and multiprocessor computers of any statistics and data management package.
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. Stata/MP runs even faster on multiprocessor servers. Stata/MP supports up to 64 cores/processors.
Speed is often most crucial when performing computationally intense estimation procedures. 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. Some estimation commands can be parallelized more than others. Across all estimation commands, Stata/MP runs 1.8 times faster on dual-core computers, 2.8 times faster on quad-core computers, and 4.1 times faster on computers with eight cores.
Speed can also be important when managing large datasets. Adding new variables is nearly 100 percent parallelized, and sorting is 80 percent parallelized.
Some procedures are not parallelized and some are inherently sequential, meaning they run the same speed in Stata/MP.
For a complete assessment of Stata/MP's performance, including command-by-command statistics, see the Stata/MP Performance Report.
|Max. no. of variables||Max. no. of right-hand variables||Max. no. of observations|
|*The maximum number of observations is limited by the amount of available RAM on your system.|
Stata/SE can analyze up to 2 billion observations. Stata/MP can analyze 10 to 20 billion observations on the largest computers currently available and is ready to analyze up to 281 trillion observations once computer hardware catches up.
Analyses do not have to be reformulated or modified in any way to obtain Stata/MP's speed improvements.
Which is to say, all platforms supported by Stata.
To run Stata/MP, you can use a desktop computer with a dual-core or quad-core processor, or you can use a server with multiple processors. Whether a computer has separate processors or one processor with multiple cores makes no difference. More processors or cores make Stata/MP run faster.
