Ireland's former national supercomputer, operated by ICHEC (the Irish Centre for High-End Computing) at NUI Galway from August 2018 until the end of its five-year service life in November 2023, after which the National HPC Service transitioned to renting time on Luxembourg's MeluXina platform per ICHEC's own later announcements. ICHEC's own infrastructure page and the independent trade outlet TechCentral.ie agree on the core cluster: 336 nodes and 13,440 CPU cores over a 100Gbit Intel OmniPath fabric, commissioned in 2018 at NUI Galway. TechCentral's article, written around the system's launch, describes the accelerator partition as Intel Xeon Phi and Nvidia P100 GPUs, while ICHEC's own current infrastructure page describes 16 Intel Xeon Phi nodes and a separate 16-node GPU partition with NVIDIA Tesla V100 PCIe GPUs; this dataset records ICHEC's own V100 description as the operator's current statement of record and notes the P100 discrepancy here rather than resolving it, since it most likely reflects the difference between an early vendor announcement and the final delivered configuration, so the accelerator edge and this row stay reported. Rmax of 665 TFlop/s (0.665 PFlop/s) is ICHEC's own stated Linpack figure; no TOP500 system page with a specific rank could be confirmed from a directly-fetched source, so ranked is left 0 even though ICHEC's own November 2018-era announcements describe that period as adding multiple new Irish TOP500 entries.
