Re: [boost] [SORT] Parallel Algorithms

Hi Steven Thanks by your ideas. I will check. Now I am designing, developing and testing several improvements for the algorithms. When finish I will prepare a clear and easy interface for to transform any sort algorithm, even the parallel, in a indirect sort, and prepare a brief document where explain how to do. Perhaps it will be a good moment for to move all the code to the namespace boost::sort Only after these things, I will begin to prepare the big benchmark. And then, I would like your experience and opinion. My idea is to make the benchmark running in a easy way, if we want know the opinion and results of other members of the Boost community, we must try to simplify their work. I will inform of my progress, but I must travel for to be with my family, and until January, I didn't run at full speed. Happy Christmas. My best wishes for you and the Boost community Francisco 2014-12-23 12:49 GMT+01:00 Steven Ross :

We can do too a benchmark with variable lenght elements with strings.

If you prepare the operations for to do in that test, I can prepare an additional benchmark with all the algorithms and your operations.

After all, we see and take a decision

The approach I've used with the boost::sort library is to set up the benchmark tests so that they read in a file of random data generated by a single application (randomgen), or any other file that is passed in for testing, and they write out their results to file. This enables better testing and debugging in case there are any problems (I directly diff the sort results when I can expect them to be identical; tune.pl does this automatically). I would prefer if you used stringsample.cpp and int64.cpp as examples of how to do this, and downloaded the boost sort library and added any modifications you need into that code. The library has a tune.pl script that runs the benchmarks. It may be helpful to write some utility templated funciton to switch between different algorithms, instead of the current approach of using a "-std" switch to use std::sort. https://github.com/spreadsort/sort There is a README there on how to install it using modular boost.
