[Help-glpk] GLPSOL - Matrix generation elapse time |

Hi,
I observed lately that the time displayed (i.e. Time used) in glpsol
logs is time used in solving the matrix.
Example (below).
~~~~~~
.
Constructing initial basis...
Size of triangular part = 579
* 0: obj = 2.315150579e+07 infeas = 0.000e+00 (0)
* 444: obj = 2.626836994e+08 infeas = 0.000e+00 (0)
OPTIMAL SOLUTION FOUND
Time used: 0.0 secs
Memory used: 33.5 Mb (35126659 bytes)
====================================
My MathProg models take time to generate the matrix. It ranges from 5
minutes to 20 minutes depending on how I formulated the constraints
and reports (i.e. writing CSV files).
Andrew, would it be possible in the next release of GLPK/MathProg to
include time elapse for matrix generation in glpsol as part of the
logs?
Xypron, et. al, how to do I create a MathProg script to track down
times, glpsol session?
E.g.
1. Start the glpsol
2. End the glpsol
3. Total time in glpsol session (e.g. in minutes and seconds)
Thanks.
