Hello! I complied ij.c and ran it with arguments "-solver 3 -restritype 2 -difconv -c 1.2 1.2 1e-3 -a 1000 1000 1000 -atype 3 -AIR 1 -device_id 0". The following errors occur. Could you help me, please?

Hypre init times:

Hypre init:
wall clock time = 0.030000 seconds
wall MFLOPS = 0.000000
cpu clock time = 0.028266 seconds
cpu MFLOPS = 0.000000

Using HYPRE_RELEASE_VERSION: 2.31.0

Running with these driver parameters:
solver ID = 3

Convection-Diffusion:
-cx Dxx - cy Dyy - cz Dzz + ax Dx + ay Dy + az Dz = f
(nx, ny, nz) = (10, 10, 10)
(Px, Py, Pz) = (1, 1, 1)
(cx, cy, cz) = (1.200000, 1.200000, 0.001000)
(ax, ay, az) = (1000.000000, 1000.000000, 1000.000000)
