Currenly LAM's support for Globus is only on machines which have the
Globus gatekeeper running. It looks like your front end machines are the
only two that have the gatekeepers and then they kind of schedule jobs to
the internal nodes. LAM currently does not support such configurations.
You need to have Globus installed and the gatekeeper running on each
machine you wish to run LAM jobs on.

# Hello everyone,

# I am using lam-mpi 7.0.6 and the Globus Tool Kit 3.2.1
# on 2 different clusters with 4 nodes each. There is a
# total of 10 machines, 2 Frontends and 8 Nodes. These

# the 2 frontends(grids) in the machine file. My
# question is, how do I get Lam to use all 10 machines,
# both frontends with the nodes behind them.
#
# Here is some more information on my setup:
# Each frontend has 2 nics, with the compute nodes on 10
# dots. Globus is installed on the 2 Frontends, and lam
# is installed on all of the machines.
#
# Frontend0.public: 192.168.10.16
# compute-0-0: 10.255.255.254
# compute-0-1: 10.255.255.253
# compute-0-2: 10.255.255.252
# compute-0-3: 10.255.255.251
#
# Frontend1.public: 192.168.10.17
# compute-0-0: 10.1.2.254
# compute-0-1: 10.1.2.253
# compute-0-2: 10.1.2.252
# compute-0-3: 10.1.2.251
#
# I created a file called machines.globus:
# machines.globus:
# Frontend0.public prefix=/usr/local/lam
# Frontend1.public prefix=/usr/local/lam
#
#
# And used the following command to boot.:
# lamboot -v -ssi boot globus machines.globus
#
# So this works fine, but how do I include the rest of
# the nodes ? Any help will be greatly appreciated.
#
# Thanks in advance,
