[petsc-users] installation on cloud platform

[Tabrez Ali]

Or you can install everything yourself.

On vanilla Debian based AMIs (e.g., Ubuntu 14.04 LTS) just make sure to 
add "127.0.1.1 ip-x-x-x-x" to your /etc/hosts followed by

$ cd
$ ssh-keygen -t rsa
$ cat .ssh/id_rsa.pub  >> .ssh/authorized_keys

After that the usual stuff, e.g.,

$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-get install gcc gfortran g++ cmake wget
$ wget http://ftp.mcs.anl.gov/pub/petsc/release-snapshots/petsc-3.6.3.tar.gz
$ ./configure --with-cc=gcc --with-fc=gfortran --download-mpich 
--download-fblaslapack --with-metis=1 --download-metis=1 --with-debugging=0
$ export PETSC_DIR=/home/ubuntu/petsc-3.6.3
$ export PETSC_ARCH=arch-linux2-c-opt
$ make all
$ export PATH=$PATH:$PETSC_DIR/$PETSC_ARCH/bin
