MPI/IPP Garching Cray T3E

Also known as RZG Cray T3E

Operated by MPCDF .

Researched with AI assistance, checked by scripts. These rows were researched by AI agents reading public operator, laboratory and vendor sources, appended by scripts and checked by automated validation; no subject-matter expert has reviewed them (how this site is made). A mechanical second-reader pass has since fetched every cited source: 1350 of 1540 systems have a readable citation that names them, and 64 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.

The read

Cray T3E of the Max Planck Society's Garching computing centre (today's MPCDF, listed by TOP500 as Max-Planck-Gesellschaft MPI/IPP). MPCDF's history page records a T3E/128 in October 1996, following a Cray T3D/128 in 1995, upgraded to 816 PEs in February 1998. TOP500 follows the growth as separate entries: 128 PEs in November 1996 (rank 34, https://www.top500.org/system/171037/), 512 in June 1997 (rank 7, Rmax 176 GFlop/s, https://www.top500.org/system/171099/), 672 in November 1997 (https://www.top500.org/system/171121/), 784 in June 1998 (rank 7, Rmax 342 GFlop/s, https://www.top500.org/system/171134/) and 812 cores from November 1998 (EV5 300 MHz, 3-D torus, UNICOS, Rmax 355 and Rpeak 487.2 GFlop/s, rank 15), the final configuration recorded here (https://www.top500.org/system/171137/). TOP500 dates the larger configurations to 1997 while MPCDF dates the system to October 1996, and 812 TOP500 cores differ from MPCDF's 816 PEs; the October 1996 date is used for first operation. It stayed on the list until June 2003 (rank 329), after the IBM p690 system (mpi-ipp-garching-p690) took over.

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.
