[PyCUDA] How much memory can I allocate using gpuarray?

[reckoner]

Hi,

According to dump_properties.py ( shown below ), I have

   Total Memory: 261824 KB

How much of this can I allocate using gpuarray as in the following:

a = gpuarray.zeros((size,), dtype=numpy.float32)

Thanks for all the great work!
