Hi,
Thank you to Lanier John, Daniel Clar, Brusche Johan, Oisin McGuinness, Martin
Rønde Andersen, Alan Rollow, Joachim Jäckel, Jose A. Fabregas Reyes for their
quick answers.
The most frequently answer is about increase data_size values

so I increase per_proc_data_size and max_per_proc_data_size:
per_proc_data_size = 2147483648
max_per_proc_data_size = 2147483648
the size is now 2 Gb and my program stop when I try to allocate more memory then
2Go!
so the swap seams possible if the limit data_size is greater then the size of
the Ram...
thank you very much to this list...
Best Regards
Josiane
