DSP can't routing

I am using openCL and the complier give the following error message

Anyone can tell me how to analyze the error?

In the report only DSP usage is above 25%, so the routing problem should due to DSP.

Does that mean we can never make full use of DSP?

What percentage of DSP is a reasonable design that can be routed?

Thank you very much
