RemoteSubmission
Aims
To create a set of utilities at the EaStCHEM RCF to allow transparent (to the user) remote job submission between the two physical clusters that make up the facility. The utilities should be generally extensible to include additional hardware or facilities that we gain access to. As much as possible, the EaStCHEM RCF should look like a single piece of hardware to the users and the utilities should minimize the set of new skills that must be learnt by the end user.
Implementation Notes
At the moment the hardware is homogeneous, this may not be the case in the future. The design of the utilities should reflect this.
Initial explorations using Globus Toolkit as the job transfer and control medium have run into problems. In particular, the discrepancy between the name of the St. Andrews cluster and the name returned by a reverse DNS lookup. The only solution to this problem seems to be to change the name of the St. Andrews cluster. If this works then this may provide the best solution.
Meanwhile, Andy Turner has been developing his own job transfer utilities using a combination of Perl and SSH - PaSS (Perl and SSH Submission).
