Nume-Lab

The Department of Civil Engineering and Architecture of the University of Pavia owns an HPC cluster dedicated to numerical simulations and at full disposal of the Lab. The cluster was designed and is maintained by the laboratory members in collaboration with AETHIA. This cluster enters the framework of the DORIAN project funded by MIUR within the framework of the Department of Excellence initiative.

The cluster is composed of 4 computational nodes combining 128 cores and 2TB of RAM. In addition, a login node with 12 cores and 64Giga of RAM is also used for development purposes. 

In detail:

MASTER NODE:

• 1 x Chassis rack 2U – 12×3,5” hot swap hybrid – Alim. ridond. 1200W Titanium
• 1 x CPU Intel Xeon 4410Y 12 core 2,0Ghz
• 2 x Memoria 32GB DDR5-4800 Reg. ECC (64GB)
• 2 x SSD 240GB 2,5” SATA (RAID1 per O.S.)
• 1 x NVMe 7.68TB 2,5” (cache)
• 8 x HDD 18TB 3,5” SATA 7200RPM (RAID6 per dati, circa 100TB utili)
• 2 x Interfaccia Ethernet 10Gb/s RJ45

COMPUTE NODE:

• 1 x Chassis 1U – 12×2,5” hot swap hybrid – Aliment. ridond. 1200W Titanium
• 2 x CPU Intel Xeon 4314 16 core 2,4Ghz (32 core)
• 8 x Memoria 64GB DDR4-3200 Reg. ECC (512GB)
• 1 x NVMe 1.9TB PCIe 4.0
• 2 x Interfaccia Ethernet 10Gb/s RJ45

This is a standalone Dell R740 machine equipped with 2xIntel Xeon Gold 6248  (2.5GHz, 3.90GHz Turbo, 20C, 27.5MB Cache (150W)), 8x64Gb RDIMM. 2933MT/s, 2x960Gb SSD e 1×1.8Tb HHD. This node is dedicated to vascular simulations using ABAQUS ™. In particular, nonlinear, contact analysis of stent implants are performed.

A GPU system dedicated to Deep Learning and Scientific Machine Learning research activities is present in the Lab. The machine was designed and is maintained by the laboratory members in collaboration with A3Cube. This cluster enters the framework of the DORIAN project funded by MIUR within the framework of the Department of Excellence initiative.

• CPU AMD EPYC 9374F 4.3 GHz 256 MB L3 1
• Core/Threads 64/128
• Memory PC5-38400 4800MHz DDR5 ECC RDIMM 1 TB
• Storage SSD SATA 6.0 Gb/s 16 TB
• OS Disk M.2 512 Gb 1
• GPU NVIDIA A100 40 GB 1

This HPC cluster is dedicated to ANSYS ™  CFD and Mechanical. It includes two machines: 

• Lenovo P520 with Xeon W-2175 (2.5GHz, 4.3GHz Turbo, 14C, 19MB Cache (140W)) and 256 GB DDR4  2666MHz 
• Dell Precision Tower 5820 with an Intel Xeon W-2123 (3.6GHz, 3.9GHz Turbo, 4C, 8.25MB Cache, HT, (120W)) DDR4-2666) and 192 GB DDR4 2666MHz RDIMM ECC. 

This cluster allows us to have 18 physical cores, 36 threads and a memory of 448 GB available for complex CFD, structural, and fluid-structure interaction analyses. Job’s queues are managed using ANSYS ™  Remote Service Manager (RSM). Moreover, this cluster is widely employed to run topology optimization of 3D printed components and perform Laser Powder Bed Fusion (LPBF) process simulations of critical components produced by ProtoLab, our 3D printing Lab.
