WIP: Fix covered nested accesses

3

In DaCe we still don't have the required tools to detect overlapped accesses in a generalized manner. Because of this, the python frontend always generates new accesses for data, even...

Reallocation of non-free SDFG symbol-dependent transients.

1

When the shape of a transient depends on a non-free SDFG symbol, for example, a for-loop variable, the code generator declares the transient as a pointer at the beginning of...

Array operation between reshaped arrays produces erroneous result

1

The following is taken from the NPBench benchmark `resnet` and involves the `conv2d` layer. Originally, DaCe did not support `np.newaxis` and the compatibility code used was: ```python for i in...

SDFG deserialization does not restore the SDFG list. Furthermore, the currently provided API methods (`SDFG.reset_sdfg_list` and `SDFG.update_sdfg_list`) do not seem to help in populating the SDFG list at all nested...

Control-flow detection bug with multiple nested for-loops and an if condition

I have the following code: ```python import numpy as np import dace as dc NA, NB, Nkz, NE, Nqz, Nw, Norb, N3D = (dc.symbol(s, dc.int64) for s in ( 'NA',...

RedundantArray and RedundantSecondArray must be split into multiple transformations, that handle separately the following cases: - Data -> Data - Array -> View - View -> Array - View ->...
