Re: [Help-glpk] GLPSOL solver running problem

[Heinrich Schuchardt]

The message "Killed/" is not created by GLPK.

Have a look at the following article:
http://unix.stackexchange.com/questions/136291/will-linux-start-killing-my-processes-without-asking-me-if-memory-gets-short

Rerun your problem with overcommit_memory = 2

sudo bash -c 'echo 2 > /proc/sys/vm/overcommit_memory'
glpsol --model controlCoverageWithConnectivity2.mod --data \
  dataInput.dat

Then GLPK should show if it has a memory problem.

Best regards

Heinrich Schuchardt
