We are currently starting a project to go to a complete new infosphere environment. Our current environment is 8.1 running in a cluster (on solaris) and our goal is to end with a grid implementation running on 8.7 (on RHEL, including new hardware).
Now I've read the webinar and the redbook on grid implementation (sg247625) but I still have some questions and I was hoping someone could provide the answer:
1. You have a Grid Enablement Toolkit, which coordinates all activities, yet what I gather from the redbook is that you also have to have a resource Manager. Now is ganglion enough to act as a resource manager or can it only act as a resource monitor ? If it can only be used as resource monitor, what is a good open source resource manager ? SGE ?
2. While the webinar and certain parts of the redbook let me to believe there is no impact on existing jobs (for the grid part), an other section explain how every jobs needs to be changed to include 3 APT parameters (APT_GRID_ENABLE, APT_GRID_COMPUTENODES, APT_GRID_PARTITIONS). Can anyone confirm if their is impact to existing jobs and in what extend ?
If anyone knows some good links to guides on migrating to grid (except for the webinar and the redbook) any help will be greatly appreciated.
And thanks to all who can provide some insight
