Say, I have two instances obj1 and obj2 of a pytorch `nn.Module`

like this one

```
class Embedding(nn.Module):
def __init__(self, dropout=0, emb_dim):
self.lin = nn.Linear(1, emb_dim)
init.xavier_uniform(self.lin1.weight, gain=np.sqrt(2.0))
def forward(self, values)
return F.relu(self.lin1(values))
```

And I have two tensors of data t1, t2 and I would like to do:

```
obj1(t1)
obj2(t2)
```

in parallel in the GPU, and intuitively this should be possible to do, since I am executing the same operations but with different data. How can I specify different GPUs for these two operations to execute them concurrently?
