Installing Remote Processing

To install the Bayesian Analysis software on a remote machine you must define a user that is to run the software. Second you must install a server that runs as that user. You must install the Bayesian Analysis software under that users account. Finally, you must describe the various machines that run the remote jobs to the Bayesian Analysis software.

Here is a much more detailed description of this process:

• First, you must define one or more user accounts on the remote machine that are to process the remote jobs. If you want to be able to keep track of time used by different project/people, you will need separate user accounts for each project. We typically use a single user account named "bayes", and in what follows we will refer to this user as "bayes" with the understanding that the name could be anything.
• Next, install a server that runs as the "bayes" user on a nonstandard port. We use the apache server, its free, comes precompiled, and is easy to configure. In the descriptions that follow we will refer to this server as if it were an apache server with the understanding that it could be anyone's server.
• Install the Bayesian Analysis software in the "bayes" account on the remote machine:
  • Copy the distribution software into the "bayes" account.
  • Install the software in the "bayes" account by issuing: bayes.remote
  • Replace the "cgi-bin" directory being used by the apache server by the "cgi-bin" directory in the "bayes" account. If the apache server is using the cgi-bin directory in the bayes account then ignore this.
• Create a queue file in either `/vnmr/bayes/help' or in the users account `vnmrsys/help' on each machines that is to submit remote jobs. The file located in `vnmrsys/help' is used in preference to the one located in `/vnmr/bayes/help'. To create the remote queue file, follow these instructions.
• Whenever a Bayesian Analysis package is entered the Magical macros that process the package check to see if remote processing is configured correctly. Specifically, they check to make sure that curl, gzip and tar are in your path and they check to see that the file "Bayes.Remove.Queue.File" exists in either /vnmr/bayes/help or in the user directory vnmrsys/help. If any of these components are missing the macros will not allow remote processing.

At this point the instillation is completed and remote job processing should be functioning.
