Bianca to be upgraded in 2022

During the coming year, Bianca will get four really high-mem nodes, 48 cores each with 768GB RAM. We will also augment the number of 256GB nodes considerably, at least 50 more of those, for a total of more than 260 nodes compared to 204 today. This will also mean that we can give more memory (and possibly cores) to each login node.
