mkbmp and threads

[Henrik Nordberg <HNordberg@lbl.gov>]

Hello,

It is possible to get file open errors when runnning mkbmp. This is
because there is a soft limit for how many file descriptors you can have
open. This is set by the shell. The default for tcsh is 64 fd:s. Use the
command:
limit descriptors 1024
to increase it. Or use the new optional argument to mkbmp to limit the
number of concurrent worker threads:

mkbmp Index/bin_spec.tdc Index 4

the last argument tells mkbmp to use a maximum of 4 threads to create
the index (plus the main thread, so top would show 5 threads).

Regards, Henrik
