As I am exploring material simulations one really hard truth that I have realized is that my gaming laptop is not at all gonnagoing to cut it for my research work. Currently I am trying to find the absorption spectra of a Quantum Dotquantum dot which has 45 atoms in total and I am using the PBE functional (so not that much accuracy). The geometrical optimization converged after 10-12 hours butby running the executable for absorption spectra (turbo_lanczos.xturbo_lanczos.x
) did not go that well. The computation ran for 23 hours after which my laptop gave out.
So
So I am looking for clusters which do not burn a big hole in my pocket. AWS and GCS came first to my mind. Although I found a tutorial(http://star.mit.edu/hpc/documentation/ec2scripts/I found a tutorial) for running on AWS I am not sure how do I know how much cores, Nodes, RAM or instances do I needI am not sure how to know how many cores, nodes, RAM or instances I need. On the other hand I canwas also not find much informationable to do the same on google cloudfind any such documentation for Google Cloud.
Could
Could you guys help me with some guidance.?
