cummaxByKey for GPU matrices?

I can't tell if cummaxByKey is implemented for GPU matrices. If it's not, then I think that it's just missing a few methods in one of the .cu files that are in BIDMat's GPU code directory? (It was recently refactored according to this commit https://github.com/BIDData/BIDMat/commit/f9f5720f9355a4def55e1596afab09a5227f597a)

Example on my Mac 10.9 laptop:

I do git pull, then do cd BIDMat/jni/src; make clean; ./configure; make; make install to get the cuda libraries. Then I do ./sbt package. The following code shows an example of the GPU version not working (but the CPU version working):
