[Coin-discuss] Multi-threaded mode for Cbc/Clp

[John J Forrest]

As far as I know Clp is threadsafe with one minor caveat.  If you use
ClpSimplex::initialSolve then that can use signal_handler to trap ctrl-c
for a graceful exit.  You can set an option to stop this happening.  I
think the worst that would happen anyway is that a random process would
stop each time you hit ctrl-c.

Hi all,

I am trying to run a shared-memory parallel experiment with OpenMP, and Cbc
and Clp are the selected MIP/LP solver, and are compiled with default
setting. However, i am not so sure that the Cbc/Clp is running in a
multi-threaded mode as expected. If i remember it correct, SYMPHONY has an
option for compilation in a shared-memory based environment. Does Cbc have
the same option? and what should i do to compile Cbc for shared-memory use,
if it hasn't been done automatically?

Many thanks!  -- yang_______________________________________________
