John the Ripper jumbo - advanced offline password cracker, which supports hundreds of hash and cipher types, and runs on many operating systems, CPUs, GPUs, and even some FPGAs
We now support Drupal7 hashes on CPU and on FPGA, but apparently not on GPU. This is weird. We should probably add an OpenCL implementation. This is similar to but simpler than sha512crypt, which we do have in OpenCL. This is in other ways similar to phpass, which we also do have in OpenCL. Combining these into a drupal7-opencl format shouldn't be too hard.
