+==== New SPACK without environments ====
+Having worked with spack environments for some time, we have encountered several severe issues which have convinced us that we need to find a more practical way of maintaining software packages at VSC.
+There are now three separate spack installation trees corresponding to the CPU/GPU architectures on VSC:
+  * skylake - Intel CPUs; works on Intel Skylake and Cascadelake CPUs
+  * zen - AMD CPUs; works on Zen 2 and 3 CPUs
+  * cuda-zen - AMD CPUs + NVIDIA GPUs; works on all nodes equipped with graphics cards
+By default the spack installation tree suitable for the current compute/login node is activated and will be indicated by a **prefix** on the command line, e.g.:
+<code>
+zen [user@l51 ~]$
+</code>
