Dear all,
At Weill Cornell Medicine we are in the process of expanding our computational resources to process cryoEM data. For technical reasons we will adopt a model where multiple nodes operate as virtual workstations that run independently with a queue system for users. In this expansion, we are looking to purchase multiple nodes, with exact numbers depending on the configuration/price of the nodes.
We are discussing with our Scientific Computing Unit on what is the optimal configuration for these nodes and we have 3 possibilities listed below. For reference, most of us work on membrane channels/transporters, often reconstituted in nanodiscs.
We would like to have suggestions on whether these specs are appropriate for our purposes or if they are overkill and current software would not take advantage of the specs of the hardware. Additionally, one important aspect to consider is the choice of using professional grade (options #1 and #2) or consumer grade (option #3) hardware.
