Building netcdf-4.3.3.1 with Intel MPI library with parallel support : FAIL: run_par_test.sh

Dear Support

I am trying to build netcdf-4.3.3.1 with parallel support using Intel MPI Library-4.1  in order to build RegCM-4.4.5.5.

I have used following environment variables before running the configure command:

export CC=mpiicc

export CXX=mpiicpc

export CFLAGS=' -03 -xHost -ip -no-prec-div -static-intel'

export CXXFLAGS=' -03 -xHost -ip -no-prec-div -static-intel'

export F77=mpiifort

export FC=mpiifort

Bizarre authenticity of host issue when running across multiple nodes with Intel MPI

I am attempting to run a job across three nodes.  I have configured passwordless ssh and it definitely works in between every node (each node can ssh to the other two without a password).  The known_hosts file is definitely correct and all 3 nodes have identical .ssh directories.  I have also tried adding the keys to ssh-agent, although I'm not sure if that was necessary either as I didn't specify a pass phrase when generating the id_rsa key (I know this is terrible security but it's temporary for the sake of testing).

Unable to launch MPI on Windows 2012

I have been using Intel MPI library on a Windows 2008 R1 server for few years without any issues. However, we recently switched to Windows Server 2012 R2, and now I can't launch MPI due to following error, when I use the command line -

mpiexec -n 1 -localroot  ./eDR_IMC.exe

" Error while connecting to host, No connection could be made because the target machine actively refused it. (10061)
Connect on sock (host=eDR-IMC2, port=8676) failed, exhaused all end points
Unable to connect to 'eDR-IMC2:8676',
sock error: Error = -1"

MPI command question

Dear all,

I use MPI to run program for the given work path. The program works when I run the following command:

mpiexec -wdir "Z:\test" -host 1 n01 1 z:\fem

However, when running the following command:

mpiexec -wdir "Z:\test" -n 1 z:\fem

The program displayed the following error:

forrtl: severe (29): file not found, unit 1, file C:\Windows\system32\parainfo\control.dat

The 'control.dat' is placed at z:\test\parainfo, and the program will search for 'control.dat' from 'parainfo' automatically.

Is it possible to us Intel MPI 5.1.0.038 with TCP over ethernet?

I have just installed Intel 5.1.0.038 into a shared NFS space meant for use by my team who share four machines connected by Ethernet.  I have a machines.LINIX file listing the hostname of each machine that I saved into the NFS space.  My intention is for us to use the library over the Ethernet connection, but I am not sure that I have configured it correctly to do this.  I am not the administrator of the machines and so I do not have explicit root access.  However, I am in the sudoer group.  During the installation, I was not able to install using the "Run using sudo privileges and password

To Intel: How to run Phi 5110p with host and Cluster Studio under Windows?

Hi,

I bought a Phi 5110p and Cluster Studio under Windows in an Intel campaign in order to use MPI to feed the Phi card. Hardwarewise I understand the major issues but softwarewise it is still unclear to me what the right way forward is, Can I work with W7 or should I use some other Windows product? The reason for clinging to Windows is that I have a lot of QuckWin based graphics that keep me informed what is going on during the computations.

Where is uninstall.sh file in the MPI 5.1 distribution?

I installed MPI 5.1.0.38 on July 16 this year, but I did not install it correctly.  I want to uninstall it, but I can't find the uninstall.sh script referenced in the Intel® MPI Library for Linux* OS Installation Guide: "To uninstall the Intel® MPI Library, go to the Intel MPI Library installation directory and run the
uninstall. sh script."  I am not sure how to uninstall the software without the script. I will appreciate any assistance in helping me find this script.

Thank you,

Rashawn Knapp

 

 

Can Xeon Phi 5110p be run on a host with Windows 7

Hi,

I have a Fortran code  heavily depending on graphic output  in order to know what is going on during the simulation. Therefore I would like to stay with Windows. Has anybody any experience with Xeon Phi 5110p on a workstation with Windows 7 (or 10)? I intend to parallize using MPI, as a third party subroutine library prohibits use of e.g. OpenMP.

Best regards
