[Clp] reading from LP file or constructing a model?

[John Forrest]

Babek,

I would construct each model from scratch.  Clp is thread safe, so you 
could easily be solving 4/8 models simultaneously - which would be more 
difficult with the file solution.  It should not be any more difficult 
and would be more efficient - assuming you can put an upper limit on 
size of matrix - and so construct a model using about 8 arrays of known 
size.
