dcc2 not work on optimized kernel

[Snoopy]

As you can read in the output...

Code:

Kernel /home/hashcat/OpenCL/m02100-optimized.cl:
Optimized kernel requested, but not available or not required
Falling back to pure kernel

emm, yes, thank you)

But what I need to do? update OpenCL? Refresh m02100-optimized.cl separately? 

Is it possible to work on optimized kernel with dcc2?

there is no optimized kernel for this specific mode
