====== RASPÈIN cluster: construction diary ======

=== October, 2018 ===

  * <color #dd3333>**The cluster has been dismantled.**</color>

=== March, 2015 ===

  * 64 nodes installed, 48 of them are already up and running.

=== February, 2015 ===

  * 32 nodes (Raspberry Pi B) are up and running. The stability of nodes is no more an issue. In the next weeks we'll add another [big] batch of nodes (Raspberry Pi B+).

=== November, 2014 ===

  * Unveiling (phase 1). Phase 2 will double the number of nodes and fix some stability issues.
