[Ipopt] METIS partition problems in IPOPT for huge amount of data

[bui le trong Phuoc]

Hi, all

I have switched to 64-Operating system with IPOPT version 3.12.5, METIS
version 4.0.3 and problem still persists with METIS partrition failure.
"" [METIS Fatal Error] ***Memory allocation failed for SetUpCoarseGraph:
gdata. Requested size: -1382763580 bytes ". "
Do i need to modify some parameters or options somewhere to avoid this
error?

Thank you and best regards,
Phuoc Bui,
