[CIG-SHORT] problem with a benchmark of 250m mesh

[Ikuo Cho]

Brad,

Thank you for the rapid reply. My colleague Makoto Hoshino, who asked
you last week to run the binary executable on a 64-bit computer,
installed Pylith from the source code. He seems to have installed Pylith
appropriately. But he said that he  has a problem when starting it. Soon
he will email to ask about this problem.

Best Regards,
Ikuo
