I work in C++ with Concert Technology (Cplex 201) on a Linux machine with the following configuration:

2*CPU: AMD EPYC™ 7702 (64 Cores 256MB Cache, 2.0GHz to 3.35GHz GHz), 512GB RAM ,200GHz. System Ubuntu.

Last week Cplex worked well with my data files. Now, when Cplex runs with the same data files Cplex begins the Branch and Bound but after few iterations stops, with no error message, and the machine goes down (all the other users of the machine lose their works).

I don’t know how to solve the this problem. All suggestions are welcome.

Thanks.

You installed Linux on VMware or with windows?
