Which version of Accelerate are you using?  You might want to have a look at accelerate.cabal (in the toplevel directory).  There are various options that you can pass during the configure step (when compiling the library).  On of the more recent options is 'pcache'.  If you pass the option '-fpcache' to configure, Accelerate will keep the generated kernels in a subdirectory called "cache".

We have also got a paper describing code generation in some detail:

I hope that helps.
