[Trilinos-Users] [EXTERNAL] Instantiation failure of Zoltan2::AMDTraits order

[Rajamanickam, Sivasankaran (-EXP)]

Hi Ryuta,

  The AMD TPL traits is missing a specialization for long int. We need to convert this using Teuchos::as as AMD doesn't support it anyway. I will fix it early next week.


Thanks

Siva

Subject: [EXTERNAL] [Trilinos-Users] Instantiation failure of Zoltan2::AMDTraits order

Hi,
It seems Zoltan2's AMD order algorithm cannot be instantiated when the typename of global and local ordinals are different. The error messages are in bold at the bottom of the compiler messages I pasted.
