I_MPI_EXTRA_FILESYSTEM settings for NFS

[Bernhard_S_]

Hello,

I am using the Intel MPI Library (as part of Intel Cluster Studio) to compile code which needs to run on a cluster using a parallel NFS storage system.

The product info FAQ (http://software.intel.com/en-us/intel-mpi-library) clearly states that parallel IO to NFS is supported. However, I run into the "File locking failed in ADIOI_Set_lock" problem discussed in http://software.intel.com/en-us/forums/topic/286114. From that post, I deduce that I need to set environment variables, but the list of possible values for I_MPI_EXTRA_FILESYSTEM_LIST in the  Intel MPI Library documentation (http://software.intel.com/sites/products/documentation/hpc/ics/impi/41/lin/Reference_Manual/Environment_Variables_Extended_File_System_Support.htm) does not include NFS. What am I missing?

Thanks,

Bernhard

Hi Bernhard,

NFS is not a parallel filesystem.  It can be added to a parallel filesystem however, and that is supported.  Do you have a small reproducer code for this behavior?
