I/O bound computing clusters
I want to build a computing cluster and have been looking into grid solutions. My understanding from grid solutions is that participating nodes have to actually sign up to participate in a computation and that an isolated piece of work is sent to the node through a request from that node (pull). Along that reasoning, would a solution whereby a controlling machine sends work to whichever node is available not be a grid solution (push)?
The problem we will be solving is data-intensive, so we will be looking at an I/O bound problem. What methodology is used whereby the data sits on one machine and the nodes use that data? Could a partitioning of the database work, whereby a node only works on the data in the partition and no other?

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.
