c++ - Very fast object allocator for small object of same size -


I have to write some code, which should be the best performance.

Requirements:

For the quick construction of the object, I need a fast object oscillator. There are only 3 pairs in my object. Allocation and delocution will generate an object at the same time.

I did a lot of research and come up with: 

  std: vector & lt; MyClass, Boost: fast_pool_allocator & lt; MyClass & gt; & Gt;

I wonder (in 2014-07):

  • Is STL something to promote: Fast: fast_pur_allocator?

There is additional information to answer some comments:

  • Code used to customize my algorithm For me:
  • I need to improve the conversion of C # code in C or C ++. I should compete against other algorithms written in pure "C". I find that there are errors in my comparison chart in my article because I have tested against the code against the compiled code for X86-debug against the code. The "C" code is very fast in the X64-release (factor 4 to 5 times faster than x86-debug).
  • And accordingly, boost: fast_pool_allocator to use the best allocator for a small memory piece of the same size query but I want to make sure that there is nothing else that can be either more standard (Part of STL) or faster.
  • My code will be developed on Visual Studio 2013 and any Windows platform (no phone or tablet).
  • My intentions are not fast code, this is the fastest code. If possible, I should not have too much twisted code and should show the code which is at least one minimum.
  • If possible, I would like to know the effect of using std: vector versus array (i.e .:: []).
  • For more information, you can see

Search for, in fact, you create a dedicated pile for objects of one size (usually 2, 4 bytes, 16 bytes, etc.) and allocate objects to the pile, in which the small size blocks that fit in your object Can be included. There are fixed-size blocks in the heap, which is very easy to manage the blocks allocated in it, a bitmap can show you which blocks are in free or in-use, so the insertion is very fast (Especially if you allocate at the end and increase in the form of a point)

As an example, you can clearly specify it for your specific object size and requirements. Kulit can.

sqlite3 - UPDATE a table from the SELECT of another one -

I have the first table article where some data is missing. In the table, articles_tmp I have a part of the missing data. So I want to update the articles. Where the path path is data in articles_tmp.path where the path is not zero . With SQLite , it does not work: update article SET path = (SELECT at.path FROM Articles_tmp as AS, WHERE at.article_id = a.id and a.asp, the text is in the form and not on. It has been transmitted) where the path is null MS Access Along with, it works fine: Update Articles Join the Inner Articles at articles_tmp articles.id = articles_tmp.id SETP articles.path = articles_tmp.path Can anyone help? Sin CE SQL Server Syntax, which I provided, was not working, here this solution With whom I have come. A little modification of your original query, but with my "correlation" suggestion added. There is a SQL Bella for this: Here is the code: update article SET path = (SELECT path from articles_tmp AS T WHERE t.id

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ

javascript - Render HTML after each iteration in loop -

I'm trying to gradually increase the font size of text on a web page. The code works in my place, although the new HTML / CSS does not render after every iteration of the loop and when all this is done, then display only the text of 100 px size. To see the text as if it is slowly zooming, I need to do this JavaScript is down because it is being used from a different file here is what I have ... < Pre> & lt; P class = "game-title" style = "font-size: 50px" & gt; Test & lt; / P & gt; Function sleep (milliseconds) {var start = new date (). GetTime (); For (var i = 0; i & lt; 1e7; i ++) {if ((new date). GetTime () - start) & gt; Milliseconds {break; CSS ('font-size', 'parseInt ($ (' game-title '). CSS (' font-size ')) + 1 + "pixels"); } While (parasont ($ ('# text'). Css ('font-size')) & lt; = 100) {sleep (1000); IncreaseSize (); Using CSS: Use of jQuery (sample):
