[CPMD-list] MPI jobs hang...for ever.

[HW Sheng]

 Hi, Axel. How are you doing? Here is an update of the crash problem I
posted one month ago. Thanks to your replies (and also discussions in other
forums), I came to conclude that the NIC drivers are the culprits, although
I was unable to pinpoint the exact problem. After upgrading the kernel to a
higher version (currently 2.4.19), I am happy that the problem has been
solved.

Cheers,

 Howard
