[Myrinet] Re: [Myricom help #8764] problem with mapper

Hi,

The mapper has mapped 8 hosts and 1 switch. There are no errors, 
the mapper is just complaining because it cannot create files 
in the directory where the mapper is run (binary/sbin I guess). 
This is a permission issue.   

These files are used to speed up the mapping process, and keep
the same GM IDs for everyone, etc.  

When you look at gm_board_info, you will see that all of the routes
for all of the nodes are computed.

Hope this helps.
Susan
