## Tests 1 (SCALING over network)

**Short description of the test**: Full (36 cores max) occupation of the computational nodes using 1 or more nodes per job.

Tests 1.1 - 1.4 test performance scaling over multple nodes over the low-latency network. The tests 1.1 - 1.4 are identical, but target different sets of nodes (1.1 = cpu nodes, 1.2 = bigmem nodes, 1.3 = gpu nodes, 1.4 gpu-mem nodes).

The following results were obtained for the current cluster (2 x Intel(R) Xeon(R) Gold 6140 CPU @ 2.30GHz per node).

**Minimal required performance for passing each of the tests 1.1-1.4**:
For each job, the results for the same number of nodes with the number of cores per node restricted to 36 should be at least 80% of the value obtained with our older aurum cluster, in the table above. For example, a job involving 10 nodes (360 cores) must report at least 0.8*104 = 83.2 ns/day.

**The following description/conditions apply to tests 1.1 through 1.4**
- **Short description of the test**: Full (36 cores max) occupation of the computational nodes using 1 or more nodes per job. There might be few unallocated nodes if the number of computational nodes is not a multiple of number of computational nodes per job in each task.
- **Storage for tasks:** This test must try all 5 different NFS shares in storage1, storage2, scratch1,  scratch2, cryo2.
- **Special test conditions:**
   - All tasks in the test need to be run sequentially without interruption to ensure that some jobs eventually use nodes placed in different sections of the cluster.
**Aditional notes**
-  There might be few unallocated nodes if the number of computational nodes is not a multiple of number of computational nodes per job in each task.
- The tests must try all 5 different NFS shares in storage1, storage2, scratch1,  scratch2, cryo2.
- All tasks in a given test need to be run sequentially without interruption to ensure that some jobs eventually use nodes placed in different sections of the cluster.
- Only 36 cores can be used for each node in this test.
- No GPU is allowed (if present in the node)
