Hi all,

I’ve created a simple flow graph with three components. The first one  
generates K \* L number of values (it is a loop), it passes them to the  
next one where I do some operations on them.  
I want it to run just once and then stop it. Therefore In The first  
component I add  
: boost::this\_thread::sleep(boost::posix\_time::milliseconds(50));  
and in the last one ‘exit’ function.

The problem is that it runs only for a limited number of K\*L. When I  
increase K or L, it does not run at all. Lets say, I set K to 100 and L  
to 2, then It runs only for 62 numbers not for all of them.

I do not know what can cause it. Can you help me?

Nasi,

you’ll need to provide more than this. Code would be best for explaining  
what you’re trying to do.

Hi Martin,

Thanks!

Ok, I attach three files here. I hope you get from the code what is  
going on there.  
ofdm\_dictionary\_3.cc is the middle components code. After processing  
inside that I pass data into ofdm\_dictionary\_2.cc

Again, it works for smaller number of int delay\_min, int delay\_max, int  
Fd\_min, int Fd\_max variables.
