ya.i got it.But my scenerio is that,we have two threads in serverside and client side respectively and i have created two pipes and two buffers for these two pipes(pipe1 and pipe2).so whenever both server and client get connected,the server or either client can starts sending message.

Events
1.writing message to pipe2(serverside)
2.client reading message from this pipe
3.client sending msg to server through pipe2
4.server reading msg from client via pipe2.

so iam asking whether we can implement above by utilizing 2 threads per each side or not.......i have done regarding this..but iam not so familiar with these threads..Can u plz help me????

serverside

client and server..got the answer..thanks for assistance

thanx Reshmi.....

Can u help me in matrix addition using 1D memory and usind 2D blocks.That should be in GPU.Matrix should be square as well as non-square matrix.

ok.thanks.we use tex2D() for fetching the memory right???.
