Hi,
I am facing a problem when trying to write on a Lustre filesystem ( v 2.12) using standard fortran IO code ( compiled with GNU gfortran 8.3). The io rate sporadically goes extremely slow ( sometime down to 20/10 kBytes/s ! ) giving the feeling that the job is just hanging. Is this problem known by the community? Is there something a user should be aware when using Fortran IO together with the lustre filesystem? The code (tarball in attachment) i am using is very simple and i would be grateful is somebody could try it to see if this behaviour is a local or general problem. Thanks in advance.
