Download, Build and Deploy MPICH 3.1 and PLDA 3.1 on Computers in a Cluster

install_mpich_and_plda.bash

# This script download, build and deploy MPICH 3.1
# (http://www.mpich.org) and pLDA 3.1 (https://code.google.com/p/plda)
# to computers in a cluster.
#
# Usage:
#
# You download and run this script from any directory.  For example,
# consider that Alice is running this script to install MPICH and pLDA
# on David's workstation in the role of Steven, she should do:
#
#  alice:> install_mpich_and_plda.sh steven@david.workstation.com
#
# This script then
#
#  1. downloads MPICH and pLDA to the working directory of Alice
#  2. scp packages to Steven's home directory on david.workstation.com
#  3. unpack packages and build them at
#     david.workstation.com:/$HOME_OF_STEVEN/
#  4. install MPICH to david.workstation.com:$HOME_OF_STEVEN/usr
#
# Prerequistics:
#
# In above case, Alice must be able to log in to
# steven@david.workstation.com in a passwordless way.  Or, Alice must
# has her public key enlisted in Steven's ~/.ssh/authorized_keys file.
# To do so, Alice can run the following command:
#
#  alice:> cat ~/.ssh/id_rsa.pub | ssh steven@david.workstation.com:~/.ssh/authorized_keys
#
# where ~/.ssh/id_rsa.pub is Alice's public key.  If Alice does not
# yet has this file, she could run the following command to generate a
# pair of private/public keys:
#
#  alice:> ssh-keygen -t rsa
#
# Install on Multiple Nodes:
#
# Alice might want to deploy MPICH and pLDA on more than one computers
# for parallel training of pLDA.  Suppose she also want to use Bob's
# computer (still in the role of Steven), she can do:
#
#  alice:> install_mpich_and_plda.sh steven@bob.workstation.com
#
# Run pLDA using MPI
#
# Suppose that Alice wants to start a parallel pLDA training job using
# 5 processes running two computers (david.workstation.com and
# bob.workstation.com), she should login to either computer, say
# Steven's:
#
#  alice:> ssh steven@david.workstation.com
#  steven@david:> ~/usr/bin/mpiexec -n 5 -f ~/hosts \
#                 ~/plda/mpi_lda \
#                 --num_topics 2 --alpha 0.1 --beta 0.01 \
#                 --training_data_file ~/plda/testdata/test_data.txt \
#                 --model_file /tmp/lda_model.txt \
#                 --total_iterations 150
#
# where the flag '-f ~/hosts' refers to a text file on
# david.workstation.com:~/hosts, which is a text file whose each line
# is a computer name.  In this case, the content of ~/hosts should be:
#
#  david.workstation.com
#  bob.wordstation.com
#
# Also notice that, before you start the training process, you must
# copy the input file (training data), in the case,
# ~/plda/testdata/test_data.txt, to all computers invoked.

Hello, so where is the script install_mpich.sh and install_plda.sh?
