Here is the result from the second run (actually two partial runs as the run got interrupted):
Code:
..a2-a3     1707945110805813310
..a2-a4     2493115507450124588
..b1-a3     1988096314966752669
..b1-c3     2638654908094170585
..b2-b3     2286406377370528139
..b2-b4     2297640117530334747
..c2-c3     2666334464745721380
..c2-c4     3067868595132318179
..d2-d3     4459055881158216540
..d2-d4     6636612996377425812
..e2-e3     7478732807317823667
..e2-e4     7614272181524255097
..f2-f3     1359948551007941806
..f2-f4     1905689484049474095
..g1-f3     2585178594020547799
..g1-h3     2022544576756325295
..g2-g3     2388698250037891063
..g2-g4     2050748957027119617
..h2-h3     1691016253163166371
..h2-h4     2546461593049578478

perft(14): 61885021521585529237

which is same result as what Peter got in 2013 Smile

More divided perfts here:

The only difference in this run is I used lockless hashing trick for all entries in hash table and the run was performed using a different set of zobrist randoms.
