I use the shared memory like this:
shared int sm[WIDTH][HEIGHT];
the size of the shared memroy should be constant, it can not be set as a variable?
Is there any solution that the size of shared memory can flexible changed with conditions outside?

Look in the SDK samples. Search for:
extern shared
for example in the nbody project.
You will have to set the shared memory size when you call your kernel, like this:
integrateBodies<false><<< grid, threads, sharedMemSize >>>
((float4*)newPos, (float4*)newVel,
(float4*)oldPos, (float4*)oldVel,
deltaTime, damping, numBodies);
Thank you
