> 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".

Dear Manuel,

Thank you for your response. I'm using 0.8.2.0 (took it from the darcs
repository.)
Now I looked at the .cabal and found the option, that resolves my
problem. Thankyou!
First of all I had hard time figuring out how to have Accelerate
generate CUDA codes...
until I found "cuda" flag in .cabal . It'll be helpful for people like
me if you include some
mentions about the options in README in the future.

Also I found out that by default, the generated file are put under /tmp .

I'll read the paper. Thank you for introduction!

Best,
