I include an old email from my experience from 22/08/18
Dear all,
I want to share my experience, especially with academic colleagues, of
running Amber18 in Amazon AWS, to give you a rough idea of the iter,
costs and performance of the system.
1. Customer activation and setup of EC2 machine
Activation of the account was straightforward, but after selecting the
server zone I had to wait a couple of days to get a P3.2xlarge instance
activated. The default limit is 0 and you need to send a customer
support request to activate it.
I selected an ubuntu 16.4 server image and 64GB of space in a EBS space.
You must select an EBS volume if you want to keep the virtual machine
once switched off. Installation of cuda and amber was straight forward
following the manual of Amber and CUDA 9.2 ubuntu installaation
istructions. I also installed intel MKL libraries.
2. Run
I did an aMD test on a system which has ~180K atoms, in TIP3P water.
AMber18 patch 9 on the Nvidia Volta V100 GPU (single card) performed an
average of 96.5 ns per day.
3. Costs
On this system 25 Hrs of usage and including data transfer accounted
with taxes for about 140 $ . The price does not include storage which is
however quite cheap.
2. Issues
Most of the issues I had to face were related to the too fast data
accumulation on the HD, with hindsight I would have selected a bigger
storage space. To overcome the problem I had to prepare a script which
rsyncs and deletes the trajectories as soon as they are done to keep the
hard drive free.
All the best
