The following math functions are missing in THC but present in TH:

• numel
• prod
• zeros
• ones
• reshape
• rand
• randn
• round
• atan2
• std (not stdall, this is per-dimension)
• var (not varall, this is per-dimension)
• cumsum
• cumprod
• maskedFill
• maskedSelect
• sort
• maskedCopy (waiting for merge, Streams for BLAS. maskedCopy. generic reduce kernels. bugfix. #167)
• multinomial (implemented, waiting for PR)
• cross
• logicalall
• logicalany
• tril
• triu
• trace
• diag
• nonzero
• range
• cat
• linspace
• logspace
• eye
• randperm
• histc
• conv2 (these are torch operators, not to be confused with nn Convolutions which are already implemented)
• conv3

When these are implemented, cwrap entries can be added that would make cutorch completely API compatible with torch
