udf parallel

Hi
I use a simple udf to simulate a dynamics mesh problem. in my udf I write some data to a txt file. when I use a serial processing no problem occurs.but when I use parallel processing (for example 4 core) in each time step the udf run 4 times then data write 4 times to txt file.
I see the forums about this problem and "Paralleling Serial UDF" but I don't understand how paralleling every serial udf.
I cant use "#if !RP_HOST" command properly.

Thanks

Hi
This is my problem too
I have to define a parallel UDF for a fully developed velocity inlet to rectangular inlet
