+ :END:
+Provide hackable, versioned, optimized, distributed, geometrical,
+arbitrary dimensional ([[id:96116550-a6a1-4700-bef7-865d0deee7ea][hypercube based]]) data storage and computation
+engine ([[id:d2375acc-af14-4f18-8ad0-7949501178c5][as inspired by the brain]]) for general purpose visual computing
+environment called [[http://www2.svjatoslav.eu/gitbrowse/sixth/doc/index.html][Sixth]].
+
+Because [[http://www.paulgraham.com/rootsoflisp.html][Lisp is hackable self defined programmable programming
+language]] it would be used to provide [[https://en.wikipedia.org/wiki/Imperative_programming][imperative programming]] support.

+** Brain
+ :PROPERTIES:

+ :END:
++ Brain appears to be natural geometrical/parallel data storage and
+ computational engine:

+ + [[https://www.simonsfoundation.org/2021/04/07/geometrical-thinking-offers-a-window-into-computation/][Geometrical Thinking Offers a Window Into Computation]]
+
++ Even more awesome is that brain appears to operate and is wired as
+ arbitrary/variable dimensional structure:

+
++ On top of this, this multidimensional space that brain represents
+ has dynamic/variable resolution/density:

+
++ Such properties allow parallel [[id:171fe375-c737-41e6-b429-a414f6abc5d8][Geometrical computation]] and
+ beautifully fits [[id:01aa65c1-3d44-44a8-9b90-58454bc6be80][CM-1 Connection Machine]] architecture (for extra

+Massively parallel (thousands of CPUs) connected via
+machine's internal 12-dimensional hypercube network allows to
+efficiently simulate arbitrary dimensional hypercube and network
+topology between computational units. So that when we are
+solving/simulating for example 5 dimensional problem, we can arrange
+computational units into virtual 5D network. See:
+http://www.mission-base.com/tamiko/theory/cm_txts/di-ch2.html
+
+we can pre-distribute data across computation units and perform
+parallel [[id:171fe375-c737-41e6-b429-a414f6abc5d8][geometrical computation]].
