MPI_Allgatherv with large message sizes

Hi,

I'm trying to collect data with MPI_Allgatherv with a large receive buffer for which the total size is larger than 2GB. As I could understand here (http://software.intel.com/en-us/forums/topic/361060) this is not supported. Unfortunately when I try to use the -ilp64 option with mpiifort I run into several problems:

1) when using include 'mpif.h' to  include mpi, then after the following commands:

mpiifort -warn -O1 -g -traceback -check bounds -i8 -c gather.f

    Dear all,

    I have installed on a cluster intel mpi. I run ./sshconnectivity.exp machines.LINUX

    on a cluster with on master and 3 nodes. using the following  machines.LINUX

    gotpeumet-node01

    gotpeumet-node02

    gotpeumet-node03

    gotpeumet-node04

     

    Than I installed mpi on all the nodes using the install.sh.

    Everything went great...apparently

    Windows cluster using ICS

    Hello everyone!

    I'm newbie in practical cluster computing and I want to create a cluster of 25 nodes on Windows 7 using Intel Cluster Studio. What do I need to accomplish this task? Just nodes with Win7 and ICS? Previously I tried to use cluster on Windows Server 2008 HPC and it had a cluster manager. Is there anything similar in ICS? Can I monitor nodes, their status and status of jobs? How do people create clusters on Windows?

    Can someone advise me articles or books to make things clearer?
    Thanks in advance.
