Machine Specifications
| CPU Model | CPU Core Info | Memory | IB Card | OS | OFED | GPU | CUDA |
|---|---|---|---|---|---|---|---|
| Intel E5-2630 | 2x8 @ 2.6Ghz | 64GB | Mellanox Connect-IB (2x56Gbps) | Redhat 6.6 | MOFED 2.4 | NVIDIA Tesla K20 | CUDA 7.5 |
The performance numbers were taken using Hoomd-Blue 1.3.3 with the following flags:
- gdrcopy enabled: MV2_USE_CUDA=1 MV2_IBA_HCA=mlx5_0 MV2_IBA_EAGER_THRESHOLD=32768 MV2_VBUF_TOTAL_SIZE=32768 MV2_USE_GPUDIRECT_LOOPBACK_LIMIT=32768 MV2_USE_GPUDIRECT_GDRCOPY=1 MV2_USE_GPUDIRECT_GDRCOPY_LIMIT=16384
These numbers were taken on Wilkes system. We would like to thank the University of Cambridge and the staff members of Wilkes for providing us access to this system.
