logistic regression using MPI

This example shows how to use learn_CRF_mpi to learn a logistic regression model using MPI. This uses identical files to the regular logistic regression example.

The call is essentially the same as for learn_CRF, except prefixed by mpirun

mpirun ./learn_CRF_mpi -m examples/logistic_regression/model*.txt -d examples/logistic_regression/data*.txt -i 1

This eventually results in the output of

weights after optimization:
 W[0]:
-0.696163   1.97284
  1.97284 -0.696163
 -1.27668  -1.27668
