Added full instruction set for a SUSE GPU instance
=Creating a new image=
Type enterCheck which distributions are supported, [[https://developer.nvidia.com/cuda-downloads here]]. All you are concerned about are the developer drivers.From this point on, tildewe will deal with a SUSE instance, periodbut the general stes will be the same. '''Only select an instance that can work with CUDA!''' With the Classic Wizard, enter select SUSE Linux Enterprise Server 11. Change the Instance Type from T1 Micro to exit a hung Cluster Compute Eight Extra Large Instance (cg1.4xlarge).Enable Termination protection.Generate your key pair and allow SSH sessionaccess to the server.Review the instance type and ensure all details are correct.Pricing information may be found [[https://aws.amazon.com/ec2/pricing/ here]].
=Installing CUDA=
Zypper is Suse's package manager; YaST could alternatively be used if more comfortable with a GUI.
First, SSH into the system, update the package cache and upgrade:
<pre>SSH -i /PATH/TO/PKEY root@ec2-...-amazonaws.com
zypper ref
zypper up</pre>
 
Install the needed packages and generate needed config:
<pre>zypper in gcc kernel-ec2-devel kernel-docs
cd /usr/src/linux
make cloneconfig</pre>
 
Restart the instance:
<pre>reboot</pre>
You will be booted from the instance, just wait for it to resume again.
 
Now get the latest CUDA install and run the file:
<pre>wget http://developer.download.nvidia.com/compute/cuda/$CUDA_MAJOR_VERSION/$CUDA_MINOR_VERSION/installers/cuda_5.0.35_$(Linux|Windows)_$ARCH_$IMG.run
chmod +x cuda_*.run
./cuda_*.run
</pre>
We only need the developer drivers. Ensure that the drivers install correctly.
 
=oclHashCat-plus=
Get oclHashCat:
<pre>wget http://hashcat.net/files/oclHashcat-plus-0.14.7z</pre>
 
To extract and use oclHashCat, we must unpackage the 7zip archive. In many distributions 7z is provided by the p7zip package. SUSE users need to download the binaries and extract it:
<pre>wget http://downloads.sourceforge.net/project/p7zip/p7zip/9.20.1/p7zip_9.20.1_x86_linux_bin.tar.bz2?r=&ts=1365352571&use_mirror=hivelocity
tar xjvf p7zip_9.20.1_x86_linux_bin.tar.bz2</pre>
 
Unarchive file, extracting full path:
<pre>7z x oclHashcat-plus-0.14.7z
cd oclHashcat-plus-0.14</pre>
Running oclHashcat-plus (in a screen session):<pre>screen./cudaHashcat-plus64 $HASHES ($DICTIONARY | -m $hashmask | --rules=oclHashCat=$RULES) </pre>oclHashcat-plus assumes unsalted md5 by default
