We then add to it an indication of which value of `nyears' prevailed for the generation of these results, and then we append those results to the destination file first identified in local macro saving.

Stata allows you to process datasets containing more than 2 billion observations if you have a big computer, and by big, we mean 512 GB or more of memory. I tried limiting it using something like "set max_memory 4g". Fortunately, laptops today have more memory than most servers did 20 years ago, and most people never have to worry about how much memory Stata is using. It is easiest to begin again. 000M set matsize 400 max. plot1. set maxvar 20000 no; dataset in memory has changed since last saved What to do? I have saved plenty I have tried . 0 ? The maximum accepted for the command "set memory" is 1g If you really need to delete a temporary file, just use erase. data space 700. Both commands will allocate 4 If you want to allocate 5m (five megabytes) every time I start Stata, you can type. But it has no effect. The second machine was a 466Mhz Mac running OS X, and it ran the tabulate command in 9. For example, if you had a data file which was 1. Samuel could obtain the equivalent of the old -set memory- command by setting min_memory and max_memory to the same amount, but I don't see why he would want to do that. > > 5. For instance, you have a long do-file. I should have read the friendly help viewer. stata -b set max_memory 10g, permanently If I now start Stata, I receive the following warning: min_memory <= memory displays a report on Stata’s current memory usage. Modified 1 year, 3 months ago. 1 billion observations if you have a big computer, and by big, we mean 512 GB or more of memory. It must either be permitted to overwrite the existing data in memory (by specifying the -clear- option) or save those results in an external data set (by specifying the -saving()-) option. Type help memory or see [R] memory for more . The easiest solution is to close stata, then reopen stata without opening a When you load a dataset into Stata, it keeps the data in memory. If you use the Linux operating system, we strongly suggest you set max memory; see Serious bug in Linux OS in[D] memory. describe Sort the data by case ID:. Virtual memory is slow but adequate in cases when you have a dataset that is too large to load into real memory. (I am using a Pentium D processor and Windows XP Professional How to work with big datasets in Stata without running out of memory. Other details: Roger Newson <[email protected]> is using Stata 11, and has some do-files that call -set memory- after -clear- while Stata matrices are still in memory: > Thanks to all at StataCorp for the new Stata 11, which I am currently > testing (in its IC flavor) on my Windows XP system, and which seems to be > working as advertized so far. If you wish to limit the maximum amount of memory Stata can use, you can set max memory; see[D] memory. However, when you add variables derived from other variables, the Datasets in memory are stored in frames, and frames are named. Then you will be able to set the memory. 2 You need to increase matsize using the set matsize command; see help matsize. New in Stata 18: Framesets. sys refuses to give me more than 1. this histogram with another histogram. 4 The memory command 6. The easiest solution is to close stata, then reopen stata without opening a Subject: Re: st: Why STATA not allow me set memory You cannot set the memory if stata currently has a dataset open. For example:. I guess that may have to do with Stata's usage of virtual memory, di "Trying to set memory to `x' Mb" set mem `x'M } on my 64-bit Linux system with 8GB of memory without any problems. Finally, you will end up with a set of new files (newfile1. 1 Memory-size considerations 6. If you routinely use very large datasets then you might want to consider setting the memory allocated to Stata to be a much larger value, say set memory 100m, permanently.

On the other hand, it also limits the size of the datasets you can process. min_memory specifies an amount of memory Stata will 2graphmanipulation—Graphmanipulationcommands Nowtherearetwographsinmemory:Graph,containingascatterplotmatrix,andscat,containing agraphofmpgversusweight . As the dataset expands, it will still need to fit in to the available memory. If the initial memory size is specified on the command line in this way, it overrides the set memory, permanently setting. Before the update, the set memory command did not do all the syntax checking it should To change the amount of memory allocated to Stata, type set memory #, where # is the amount of memory you want to allocate.

This has significant speed advantages, provided the data set actually fits in the physical memory available. That provision is of little consequence these days. set maxvar 80000 // Default is 5000 set segmentsize allocates memory My modest six-month-old Dell PC has 4 GB RAM. > > Just because you have Load the dataset using the virtual memory system. SE！之前当内存不足时，我已用过set memory的命令把内存加大了，但很快就不够用了！谢谢！,经管之家(原人大 st: set memory with Stata/MP 10. Therefore I need to set an upper bound on memory usage (indeed Stata already crashed the system). Min Tang wrote: You cannot set the memory if stata currently has a dataset open. 0 on a Linux machine and am trying to permanently change Stata's maximal memory allocation. Thanks a bunch. memory displays a report on Stata’s current memory usage. D. If stata changes its memory usage throughout the job, and offers no ability of the user to set memory, one could run a really long job almost to the end that doesn't need much In Stata 12, these commands are not necessary because memory is managed automatically. It works when the said data set consists of nothing but the numeric variables that go into the model. . If so, save this dataset and exit from Stata. save "c:\A1\ttt", replace (note: file c:\A1\ttt Subject: Re: st: Why STATA not allow me set memory Or, simply close the dataset (don't exit Stata), set the memory, and reopen the dataset. set segmentsize 32m 1m-32g Output settings set more off set rmsg off set dp period may be period or comma As of Stata 11.
