You'd use Cecil or some other such library to load the compiled assembly, change the IL code and save it back. Depending on what you really want to do to the code, in most cases it might be enough to just change method calls to go through a runtime library you can write in C# that will dispatch the call to a pool of threads (obviously only for a selected subset of calls). lupus -- - [EMAIL PROTECTED] debian/rules [EMAIL PROTECTED] Monkeys do it better ___ Mono-devel-list mailing list Mono-devel-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-devel-list

Hi!Sounds very interesting!If I am correct you want to detect (thus extract) parallelism from a CIL image right?Do you have any research paper describing the algorithm you plan to use ?Please keep us informed of your advancement :) --cv2006/10/5, Khaled A.

Do you plan to automatically detect when parallel usage is possible or will it be something that the C# program's author can specify? Martin On 10/5/06, Cedric Vivier [EMAIL PROTECTED] wrote: Hi!

Yes, the extra information will help JIT to understand the nature of the program. Do you have any research paper describing the algorithm you plan to use ? Well, one of the student of Prof. Tarek (University of Toronto) have modified Jikes (the IBM java compiler) to do something similar. His changes in compiler created two files: a java byte code and a registry for runtime environment. And his changes in JIT will thread any method it finds and will use the registry information to handle dependency issues. http://www.eecg.toronto.edu/zjava/ Prof. Tarek has done a lot of research on inserting extra information in binary image. So I am guessing he has what I would need. The first step is to research on .NET to find out what kind of optimization for multicore processor (parellelism) is currently available? Please keep us informed of your advancement :) Sure, thanks. -- cv 2006/10/5, Khaled A. K. Mohammed [EMAIL PROTECTED]: Hi, I am doing a course on compiler.

Automatic is the plan for now. I might use the compiler to add Attributes [(...)] to methods during compilation, which can probably be added by application developers too. If you have other suggestions, please let me know. Martin On 10/5/06, Cedric Vivier [EMAIL PROTECTED] wrote: Hi! Sounds very interesting!
