## Tests 1 (SCALING over network)

Tests 1.1 - 1.4 test performance scaling over multple nodes over the low-latency network. The following results were obtained for the current cluster (2 x Intel(R) Xeon(R) Gold 6140 CPU @ 2.30GHz per node).

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).

| Cores (Nodes)   |  36 (1) |  72 (2) | 144 (4) | 216 (6) | 288 (8) | 360 (10) | 432 (12) | 504 (14) | 576 (16)| 648 (18)| 720 (20)|

| ------ | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- |

| ns/day |  13 |  25 |  48 |  71 |  90 | 104 | 130 | 152 | 167 | 175 | 188 |

**Minimal required performance for passing the test**:

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 higher than 80% of the value obtained with our older aurum cluster, in the table above.

**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.
