ICAM BlueGene/P – UVT HPC Center – ICAM BlueGene/P Supercomputer


ICAM BlueGene/P is a supercomputer designed for highly scalable applications. Our infrastructure is based on one IBM BlueGene/P rack with 1,024 physical CPUs (4,096 cores) and more than 1TB of RAM memory. The computing power is backed by a 19TB (RAID 5) storage system delivered using a 10Gbps Ethernet connection. The full specifications of the supercomputer are described in the table below.

ICAM BlueGene/P is managed by two special nodes, one dedicated to users (the head node) and one dedicated to management and monitoring activities. The storage is exported to the supercomputer by two NSD nodes connected directly to the storage system. The storage space is exported using IBM GPFS solution. ICAM BlueGene/P is cooled by air using two dedicated cooling units. The cooling model splits the cooling zone into two areas: hot zone above the technical floor and cold zone under it. The two cooling units are working in cluster mode to ensure high-availability.
