Since you mentioned that you are new to AWS, you should be able to get
the benefits of the free tier:

Basically, you can use 30 GB of EBS storage free of charge. On the
other hand, if you pull data from AWS to your local harddrive
everytime you are done with the instance, then you will need to pay
for I/O & data transfer costs.


I am trying to find the version of the NVIDIA Driver & CUDA toolkit
installed on the CG1 AMIs, but instead of booting up an instance to
find out what's there, is there a page that lists the additional
software packages installed in the AMIs?? So far, I could only find:


Open Grid Scheduler / Grid Engine

Scalable Grid Engine Support Program
