[Coin-discuss] ClpCholesky

[John J Forrest]

Matt,

Clp can use WSSMP.  It only used an old version of WSSMP inside OSL if 
WSSMP_BARRIER was 1.

It can also use University of Florida sparse cholesky routines - look at 
top of ClpCholeskyUfl.hpp.  You need to get UFsparse and add configure 
options to pick up include and libraries.  Simplest is to define 
UFL_BARRIER and just use amd.h and -lamd.  You should get somewhat better 
performance by also defining CLP_USE_CHOLMOD and using cholmod.h and 
various libraries depening on how you built cholmod.

John

Which, if any, of the 3rd party Cholesky codes are working for CLP 
interior?

I see some comments in the WSSMP_BARRIER code that seems to use OSL 
libraries.

Thanks,
Matt
