Using the GPU cluster a huge amount of Monte Carlo simulation data is collected for a wide interval of coupling values. This gives a possibility to determine the low bound on the coupling constant \\lambda_0 when the transition happens and investigate its type. We found that for the values of \\lambda close to this bound a weak-first-order phase transition takes place. It converts into a second order one with the increase of \\lambda.
