[Pw_forum] Insufficient Virtual Memory

[Vo, Trinh]

Dear Axel,

Yes, I read the README file.   I first just run "run_example" to get the input files (I wanted to see what they are).  I then run each job individually.  Since I saw in one of previous emails, you mentioned the following link, which is related to the benchmark of the 8cores:
http://cp2k.googlegroups.com/web/cp2k-water-bench-cmm.png?gda=cZtL20oAAABKcjB2R2-kyOTBNGr0GXCNfKm1opB3ppoZQi3FVKdigwDOq5Mi_ip_cCKVysjiE_BA1utot6QxKJxvVe1Mw7MU_e3Wg0GnqfdKOwDqUih1tA

In the plot, I saw the result for 512 H2O and 4core/nodes.  Thus, I tried to repeat all the calculations to compare, but I could not run that case.

Thank you,

Trinh
