Using cuBLAS with complex numbers from Thrust

QUESTION

Using cuBLAS with complex numbers from Thrust

Asked 2017-Apr-17 at 17:07

In my code I use arrays with complex numbers from thrust library and I would like to use cublasZgeam() in order to transpose the array.

Using complex numbers from cuComplex.h is not a preferable option since I do a lot of arithmetic on the array and cuComplex doesnt have defined operators such as * +=.

This is how I defined array which I want to transpose

...

Despite your protestations to the contrary, the C++ standard library complex (or thrust::complex) most certainly does work with CUBLAS. The cuComplex and cuDoubleComplex are design to be binary compatible with standard host complex types so that data does not be translated when passed to CUBLAS functions which use complex data on the device.

A simple modification to the code you posted in comments works exactly as you might imagine:
