用程序。该程序即是为使用苹果电脑，喜欢学习，并使用stata的朋友提供的。其轻小的体积，与快速的反映，十分便于使用，性能上
也比spss提升了不少。
Stata/MP is the fastest and largest version of Stata. Most computers purchased since mid-2006 can take advantage of the
advanced multiprocessing of Stata/MP.
Stata/MP is a version of Stata/SE that runs on multiprocessor and multicore computers. Stata/MP provides the most extensive
support for multiple-processor computers and multicore computers of any statistics and data-management package.
The exciting thing about Stata/MP, and the only difference between Stata/MP and Stata/SE, is that Stata/MP runs faster—much
faster. Stata/MP lets you analyze data in one-half to two-thirds of the time compared with Stata/SE on inexpensive, dual-core
desktops. Stata/MP runs even faster on industrial-grade multiprocessor servers. Stata/MP supports up to 64 processors.
The graph below summarizes the performance differences between Stata/SE and Stata/MP.
In a perfect world, software would run twice as fast on two processors, four times as fast on four processors, eight times as fast on
eight processors, and so on. Across all commands, Stata/MP runs 1.4 times faster on two processors, 2 times faster on four
processors, and 2.5 times faster on eight processors. These values are median speed improvements.
Half the commands run even faster, and a few achieve performance even beyond what might be considered theoretically
possible (more than twice as fast on two processors, etc.) because multiprocessor systems have multiple caches, too.
On the other side of the distribution, a few commands do not run faster, often because they are inherently sequential (time-series
commands).
We worked hard to make sure that the performance gains for commands that take longer to run would be greater. Across all
estimation commands, Stata/MP runs 1.7 times faster on dual-core computers, 2.8 times faster on quad-core computers, and over
5 times faster on computers with eight processors.
For a complete assessment of Stata/MP’s performance, including command-by-command statistics, see the white paper Stata/MP
Performance Report.
Stata/MP is 100% compatible with Stata. Analyses do not have to be reformulated or modified in any way to obtain Stata/MP’s
speed improvements.
Stata/MP is available for the following operating systems:
Windows (32- and 64-bit processors)
Mac OS X (64-bit Intel processors)
Linux (32- and 64-bit processors)
Solaris (64-bit SPARC and x86-64)
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 means that Stata/MP will run faster. |
