Straight outta Shandong cluster noobs set new LINPACK world record

31.7 trillion flops – pretty sporty

HPC Blog Another world record has fallen. Asian Student Cluster competitors have broken the student LINPACK record with an amazing score of 31.7 TF/s. This barely tops the former record of 31.15 TF/s set at SC16 by the University of Science & Technology of China.

The new record holder is Weifang University of Science & Technology, a team out of Shandong province, which has a modest population of 97 million folks.

Weifang is a young university, established in 1984, and this is the first time they've sent a team to any student cluster competition. It's pretty remarkable to see a new team break an existing record right out of the gate like this. Impressive.

So what put Weifang over the top? The first thing that jumps out at me is their configuration – they're driving a five-node cluster with a whopping ten Nvidia P100 accelerators. While there are several teams using eight P100s, Weifang is the only team to sport ten of these compute monsters.

Another newcomer, the University of Warsaw, grabbed second place by an incredibly small margin. Warsaw is driving a small four-node cluster equipped with eight P100 GPUs and only 512GB memory.

Again, it's very surprising to see new teams do this well on any component of the competition, much less establish new records. Both Weifang and Warsaw are teams to keep an eye on – we may be seeing the rise of a couple of new tier-one teams.

Hong Kong Baptist nailed third place, finally breaking through into the top echelon – at least as far as LINPACK goes. They've been knocking on the LINPACK door for the last few years and it's finally opened for them. Like the other top finishers, their cluster is on the small side, just four nodes and 512GB memory, but driven by eight P100s.

Tsinghua University is a bit of an anomaly in this race. They have a large eight-node cluster equipped with eight P100 GPUs. They must have throttled down their CPUs to free up the juice to let their GPUs sing. Shanghai is also pushing a larger cluster, with seven nodes and eight GPUs. Dalian has a configuration much like the top three finishers, with only four nodes, but a full double brace (eight) of GPUs.

The average LINPACK score at ASC17, 16.475 TF/s, is down a little from the record 18.196 TF/s average established at SC16. The ASC17 median score (15.55) is also down when compared to the SC16 median of 20.445. This is due to a few teams at ASC17 either scratching or turning in ultra-low scores due to hardware and software problems.

As you can see by the chart above, this new record isn't a huge advance over the mark set at SC16, but, hey, it's a world record and certainly worth bragging about, right?

I'm hoping that the residents of Shandong province greet the returning Weifang team with a parade and statues built in their honour. It's the least they can do for these brave cluster warriors.

Stay tuned for more ASC17 coverage. We'll have more results, interviews with the teams, and a complete and comprehensive analysis of the final results.
