- Thus, you will be able to log into two different home directories, within two completely different systems:
scheraga.chem.cornell.edu
matrixtest.scheraga.chem.cornell.edu
- Your account and password on the new Matrix are the same as the old Matrix.
- See section below, "Get access to your account", within the "(2) Information relevant for testing and after testing" section.
- Continue to use the old Matrix cluster for your production research work.
- Use the new cluster ONLY to confirm it will work for you once we cut-over from the old Matrix. Do not use it for production research.
- Interruptions to the new Matrix during this testing phase may occur at any time, with no advanced warning.
...
- See the storage chart for more details on disks & partitions in the new cluster, and how that compares to the old Matrix.
- All research applications are installed under “/software”.
- See section above, "How is the new Fall 2014 Matrix different than the old Matrix?", for details.
- Info Get info on the nodes on the new Matrix which are available during testing.
- See chart with full details:
- Summary info, true during Phase Two testing:
- Initially about 16 18 nodes will be made available to all researchers.
- This represents the newly purchased nodes and two of each type of 5 types of old node.
- There are 8 new compute nodes (m108-m115) accessible. Each new node has 20 cores available.
- For testing, select old Matrix nodes will be moved to the new Matrix to ensure adequate computing capacity during testing.
- During testing, GPU's are not available in the new cluster.
- However, 2 of their nodes will be running as just CPU nodes.
- Initially about 16 18 nodes will be made available to all researchers.
- See chart with full details:
- Queuing information
- No Express queue available for testing.
- An Express queue will be provisioned when new Matrix is in production.
- The default queue is dque instead of express as the node is not no node has been assigned to be available for express Express queue.
- No Express queue available for testing.
Important notes in WHAT DATA
...
WILL BE ERASED AFTER TESTING. And what data is saved after testing.
ChemIT will save all end-user's home directories as they build them up on the new Matrix.
