I have been searching for some days for solid information on the possibility to accelerate LINQ queries using a GPU.
Technologies I have "investigated" so far:
- Microsoft Accelerator
- Cudafy
- Brahma
In short, would it even be possible at all to do an in-memory filtering of objects on the GPU?
Let´s say we have a list of some objects and we want to filter something like:
var result = myList.Where(x => x.SomeProperty == SomeValue);
Any pointers on this one?
Thanks in advance!
UPDATE
I´ll try to be more specific about what I am trying to achieve :)
The goal is, to use any technology, which is able to filter a list of objects (ranging from ~50 000 to ~2 000 000), in the absolutely fastest way possible.
The operations I perform on the data when the filtering is done (sum, min, max etc) is made using the built in LINQ-methods and is already fast enough for our application, so that´s not a problem.
The bottleneck is "simply" the filtering of data.
UPDATE
Just wanted to add that I have tested about 15 databases, including MySQL (checking possible cluster approach / memcached solution), H2, HSQLDB, VelocityDB (currently investigating further), SQLite, MongoDB etc, and NONE is good enough when it comes to the speed of filtering data (of course, the NO-sql solutions do not offer this like the sql ones, but you get the idea) and/or the returning of the actual data.
Just to summarize what I/we need:
A database which is able to sort data in the format of 200 columns and about 250 000 rows in less than 100 ms.
I currently have a solution with parallellized LINQ which is able (on a specific machine) to spend only nano-seconds on each row when filtering AND processing the result!
So, we need like sub-nano-
