Explorer (Northeastern)
Also known as Northeastern Explorer
Operated by Northeastern University at MGHPCC Holyoke .
Phase 1 seed dataset, compiled by hand. These rows were built from public operator, laboratory and vendor sources. A mechanical second-reader pass has since fetched every cited source: 1092 of 1153 systems have a readable citation that names them, and 40 are genuinely weakly sourced. Every claim carries its source and a confidence tier. Treat anything below verified as a lead, not a citation.

Figures are as last publicly reported for the configuration described below, not a live measurement. Where a system was upgraded in place, the post-upgrade configuration is shown and the earlier one appears in the timeline.
What this machine is made of
One row per supplier relationship. “Supplier at build” is the company that shipped the part at the time; where that company has since been acquired, the parent it rolls up to today is shown beside it. That distinction is what makes ticker-level aggregation possible across a thirty-year dataset.
| Role | Part | Supplier at build | Quantity | Confidence | Source |
|---|---|---|---|---|---|
| Accelerator | - over 525 NVIDIA GPUs (P100, V100, T4, A100, A5000, A6000, L40, H100, H200) | NVIDIA | 525 reported | Reported | rc.northeastern.edu |
| CPU | - Intel Xeon CPUs from Sandy Bridge through Sapphire Rapids | Intel | - | Reported | rc.northeastern.edu |
| CPU | - AMD Zen to Zen4 CPUs | AMD | - | Reported | rc.northeastern.edu |
The read
Northeastern University's shared research HPC cluster, run by its Research Computing team at the Massachusetts Green High Performance Computing Center in Holyoke and successor to the Discovery cluster. The hardware page states over 45,000 CPU cores and over 525 GPUs, mixing Intel Xeon (Sandy Bridge to Sapphire Rapids) and AMD (Zen to Zen4) CPUs with NVIDIA P100, V100, T4, A100, A5000, A6000, L40, H100 and H200 GPUs, 200 Gbps or 100 Gbps InfiniBand on the high-speed nodes and 6 PB of high-performance storage. A Northeastern April 2025 post adds 32 H200 GPUs with 140 GB each, quoted at over 2 PFLOPS peak double precision. MGHPCC's project page describes the same cluster as 50,000 CPU cores and 200 GPUs, a smaller and older figure, so the figures here follow the university's current hardware page and are marked reported. The Holyoke site record is the shared MGHPCC campus; no FLOPS are recorded because no benchmark is published.

Source check
We fetched this system's own citations and recorded whether each page actually mentions it. This is a corroboration signal, not a fact check, and it is published so you can see how well the sourcing holds up rather than take it on trust.
