If you have results, in some static form, you can dynamically mount NFS connections as needed to acces those directories.
Is your "backbone" 1GB or 10GB? If you can create a subnet for the fast NICs and each UNIX box has a 10GB NIC, this is very acceptable - what we do now. We create a job's data, notify the other box, it NFS mounts the dataset readonly, and away we go.
There is another issue to consider. Even though you may get great throughput, some boxes have issues. Solaris with older Qlogix cards takes a hit on interrupts. Because the cpu does a lot of work for the NIC.
All of this is a case of limiting factors, something you see in Science a lot. When you raise the bar on one limit (cpu) then some other resource becomes limiting (I/O in this case or interrupt stack). Since it is not economically feasible to build highways to completely handle rush hour traffic, so it is with computers. As long as it does not hurt production, and you get more processing power, you are okay. You did pay for the hadware, so use it.

grid-ca-sign
GRID-CA-SIGN(1) Globus Commands GRID-CA-SIGN(1)
NAME
grid-ca-sign - Sign a certificate with a SimpleCA for use on a grid
SYNOPSIS
grid-ca-sign [-help] [-h] [-usage] [-version] [-versions]
grid-ca-sign -in REQUEST -out CERTIFICATE
[-force] [-dir DIRECTORY]
[-openssl-help] [OPENSSL-OPTIONS]
DESCRIPTION
The grid-ca-sign program signs a certificate based on a request file with a CA certificate created by grid-ca-create. The new certificate
is written to a file. If the CA has already signed a certificate with the same subject name as contained in the certificate request, it
will refuse to sign the new request unless the -force option is provided on the command-line.
If run as a privileged user, grid-ca-sign uses the CA certificate and configuration located in ${localstatedir}/lib/globus/simple_ca to
sign the certificate. For a non-privileged user, grid-ca-sign uses the CA certificate and configuration located in $HOME/.globus/simpleCA.
The grid-ca-sign program an use a different CA configuration and certificate by using the -dir option.
The full set of command-line options to grid-ca-sign follows. In addition to these, unknown options will be passed to the openssl command
when creating the self-signed certificate.
-help, -h, -usage
Display the command-line options to grid-ca-sign and exit.
-version, -versions
Display the version number of the grid-ca-sign command. The second form includes details about the package containing grid-ca-sign.
-in REQUEST
Sign the request contained in the REQUEST file.
-out CERTIFICATE
Write the signed request to the CERTIFICATE file.
-force
Revoke any previously issued certificate with the same subject name as in the certificate request and issue a new certificate.
Otherwise, grid-ca-sign will refuse to sign the request.
-dir DIRECTORY
Sign the certificate using the Simple CA certificate and configuration located in DIRECTORY instead of the default.
-openssl-help
Print the command-line options available for the openssl ca command.
EXAMPLES
Sign a certificate request using the simple CA in $HOME/SimpleCA
% grid-ca-sign -in usercert_request.pem -out usercert.pem -dir $HOME/SimpleCA
To sign the request
please enter the password for the CA key:
The new signed certificate is at: /home/juser/.globus/simpleCA/newcerts/01.pem
ENVIRONMENT VARIABLES
The following environment variables affect the execution of grid-ca-sign:
GLOBUS_LOCATION
Non-standard installation path of the Globus toolkit.
