I have a question: What is the maximum supported dictionary size on VGA with 512MB RAM ?

the size depends on the vendor. if you're on ATI the OpenCL runtime is limited to 128MB size (without tuning environment parameters). if you're on NV it is nearly the whole available memory of your card.

but another very important thing: to optimize the speed it is required to convert each word of a wordlist to a structure the gpu kernel can work with more easily. the size of this structure is 20 bytes.

so it is hard to say what the maximum size of a wordlist is. it is better to know the number of words in the wordlist. if you have 1m words in your wordlist, this requires about 20mb gpu memory.
