<div dir="ltr"><div><div>Dear devs,<br><br>sorry to bother you with this again, but can you please give me a final word on whether KSPGMRES in combination with PCASM is currently supposed or not to work with MATMPIAIJCUSP on multiple-GPUs as it does (that I can clearly see) on 1 GPU? Do you have a test for that?<br>
<br>Again, for what I can see, residuals are inconsistent with 1 or more GPUs and you don't get the same discrepancy with, for instance, PCJACOBI (same exact residuals on single and multi-GPU). This makes me think (maybe wrongly) that my part of the interfacing with PETSc is right.<br>
