Charm++ parallel programming system

[Filippo Gioachin <gioachin AT uiuc.edu>]

Please do not cast the callback to a CmiHandler, they are not the same thing.

CcsRegisterHandler accepts a callback as second parameter (for an example look at tests/charm++/python/server.C)

Hello Fillippo,

I got the idea thank you, but I get a problem that I am not able to solve.

The situation is this one. I have a main.ci with a mainchare with 2 entry method void launch() and void done(). In each of those a simple CkPrintf is inside.

Knowing that int the Main::Main(CkArgMsg *msg) I create 2 CkCallback functions like this:

 CkCallback launchCB(CkIndex_Main::launch(),thisProxy);
 CkCallback doneCB(CkIndex_Main::done(),thisProxy);

But after creating this two callbacks, I can't get CcsRegisterHandler to work properly.

CcsRegisterHandler("launch",(CmiHandler)launchCB); //a example of the CcsRegisterHandler

What am I doing wrong??

Thank you in advance as always,

Denis

Hello Denis,

any Charm++ application is automatically also a Converse application. CCS is already compiled in you application. You can put calls like CcsRegisterHandler directly into you charm++ code (say mainchare constructor). If you specify a CkCallback as destination, your desired entry method can be called via CCS.

Filippo

Hello to everybody,

I have been looking and reading about Converse Client-Server architecture and I think that, as some of you pointed out before, would be a perfect solution for my problem. I have looked to the converse examples and read the manual.

So I think that the architecture in my case should be a process in C++ and Qt4, and another "parallel process" in charm++ (I put "parallel process" because it will be multiple processes in a cluster in charm++). Thus, I can't just put converse code in Charm++. So, how do I become my Charm++ application in a type of Converse server, so as to communicate with my Qt4 Client??

Thank you in advance,

Denis
