Hi Reza,

Our cluster was recently upgraded to InfiniBand and switched to gpfs. Since then the rate of mysterious mpi crashes/hang during relion runs has decreased quite a lot. And relion runs faster. Is it due to gpfs, to InfiniBand or to the combination of both? I do not know. 

Cheers
Ben

Hi,

Can anyone describe some of their experience with deploying and using a distributed filesystem for image analysis? Is it appropriate to say that NFS is antiquated, slow and less secure than the younger systems like Lustre, Gluster, Ceph, PVFS2, or Fraunhofer? 

Best wishes,
Reza
