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/Environm...) does not include NFS. What am I missing?
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?
