Using GPUs with Statevector Simulator in Qiskit 1.0

Question

I'm trying to use the AerStatevector method with GPUs. I know that GPUs on my server are correctly configured, and indeed, if I use AerSimulator I'm able to use them with no problem. Now, by using the following code: AerStatevector(qc, device='GPU') where qc is a given quantum circuit, I'm getting the following error:

 RuntimeError: This program was not compiled for SM 61  
: cudaErrorInvalidDevice: invalid device ordinal

On the other hand, If I use just AerStatevector(qc), it works correctly. Any hints? More generally, I'm moving to qiskit 1.0, and I would like to perform statevector simulations by using GPUs.

Where can I look for some tutorials?

Answer 1

Check this tutorial out. There's a mention of using GPU with AerSimulator.

Answer 2

The qiskit-aer-gpu module depends on cuTensorNet. cuTensorNet supports GPU architectures of Volta, Ampere, and Hopper, which are all sm70 or higher.

Since you have sm61, I am guessing your GPU architecture is Pascal.

Unfortunately, I do not think there is a solution to this mismatch in architecture.
