[Lustre-discuss] mpi-io support

[Cédric Lambert]

Hi WangDi,

12521 is a private bugzilla. Could it be possible to access it ?

Generally speaking, do you know performance problem with ufs adio driver with small I/Os from multiple clients and if it is the case should it be enhanced with lustre adio driver ? 

Do some bugzilla exist about this problem ?

Regards
Cédric Lambert
