RedHat5.4 installation mpich2-1.4.1p1 Process

1. Configure the environment (1) Configure/etc/hosts (root User) 202.117.10.37www.linuxidc.com (master node) 202.117.10.50www.linuxidc.net (slave node) on the two machines respectively (2

1. Configure the environment

(1) Configure/etc/hosts on the two machines respectively (root User)

202.117.10.37 www.linuxidc.com (master node)

202.117.10.50 www.linuxidc.net (slave node)

(2) create linuxidc users on the two machines respectively

(3) Configure NFS

Mount the/home directory on the master node www.linuxidc.com from www.linuxidc.net and set it to mount on startup

(4) Configure login without a password (use linuxidc user on www.linuxidc.com)

1. Ssh-keygen-t rsa
2. Cp ~ /. Ssh/id_rsa.pub ~ /. Ssh/authorized_keys

2. Install mpich2 (the linuxidc user is on the www.linuxidc.com node)

(0) Preparation

Create under/home/linuxidc

Program/mpich2-install directory

Softdirectory (set mpich2-1.4.1p1.tar.gz)

Study/mpi-study directory

(1) Extract

Tar-zxvf mpich2-1.4.1p1.tar.gz

(2) Installation

1. ./Configure-prefix =/home/linuxidc/program/mpich2-install/
2. Make
3. Make install

(3) simple configuration

Linuxidc@www.linuxidc.com ~ $ Vi. bashrc

Export PATH =/home/linuxidc/program/mpich2-install/bin: $ PATH

Linuxidc@www.linuxidc.com ~ $ Source. bashrc

(4) Verification

1. Linuxidc@www.linuxidc.com ~ $ Which mpicc
2. ~ /Program/mpich2-install/bin/mpicc
3. Linuxidc@www.linuxidc.com ~ $ Which mpiexec
4. ~ /Program/mpich2-install/bin/mpiexec

3. Test

(1) machinefile // still use ip address. An error occurred while testing the instance with the machine name.

Linuxidc@www.linuxidc.com ~ $ Vi machinefile

1. 202.117.10.37: 4
2. 202.117.10.50: 2

(2) test

1. Linuxidc@www.linuxidc.com ~ $ Mpiexec-f machinefile-n 6./soft/mpich2-1.4.1p1/examples/cpi
2. Process 0 of 6 is on www.linuxidc.com
3. Process 1 of 6 is on www.linuxidc.com
4. Process 3 of 6 is on www.linuxidc.com
5. Process 2 of 6 is on www.linuxidc.com
6. Process 4 of 6 is on www.linuxidc.net
7. Process 5 of 6 is on www.linuxidc.net
8. Pi is approximately 3.1415926544231239, Error is 0.0000000008333307
9. Wall clock time = 0.001708

4. Enhanced Configuration

(1) Add machinefile to the Environment Variable

Cp ~ /Machinefile ~ /Programs/mpich2-install/

Linuxidc@www.linuxidc.com mpich2-install $ vi ~ /. Bashrc

1. Export MPI_USEP4SSPORT = yes
2. Export MPI_P4SSPORT = 22
3. Export P4_RSHCOMMAND = ssh
4. Export PATH =/home/linuxidc/program/mpich2-install/bin: $ PATH
5. Export HYDRA_HOST_FILE =/home/linuxidc/program/mpich2-install/machinefile

[Linuxidc@www.linuxidc.com mpich2-install] $ source ~ /. Bashrc

(2) test (that is, you do not need to declare machinefile in the command line. The default value is HYDRA_HOST_FILE in the environment variable)

1. Linuxidc@www.linuxidc.com ~ $ Mpiexec-n 7./soft/mpich2-1.4.1p1/examples/cpi
2. Process 1 of 6 is on www.linuxidc.com
3. Process 2 of 6 is on www.linuxidc.com

5. Process 0 of 6 is on www.linuxidc.com
6. Process 4 of 6 is on www.linuxidc.net
7. Process 5 of 6 is on www.linuxidc.net
8. Pi is approximately 3.1415926544231239, Error is 0.0000000008333307
9. Wall clock time = 0.001440
