RIKEN: “Fugaku” in Japan, Performance released on ISC 2020/TOP500: HPCG, HPL-AI, Graph500
RIKEN: Japan “Fugaku”
TOP500:
It has the world’s highest performance in four fields, HPCG, HPL-AI, and Graph500, and has been certified as No. 1 in the world.
International Supercomputing Conference (ISC 2020) was held online on June 22nd,
International Supercomputing Conference (ISC 2020)
It ranks the fastest computers in the world using the execution performance of LINPACK as an index.
Started in 1993. The rankings are announced twice a year in June and November every year.
What is LINPACK:
It has been used for many years as an index to evaluate the standard performance of supercomputers.
Measures the speed of solving general linear equations (dense matrix) in science and engineering.
FUGAKU, installed at RIKEN, achieved 415.5 PFLOPS.
We have dismissed Summit from Oak Ridge National Laboratory, which used to be number one, to number two.
It showed a big difference of 2.8 times that of Summit’s 148.6 PFLOPS.
“HPCG”:
The iterative method (CG method), which is said to be close to the performance of a real application, evaluates the speed of solving linear equations of a sparse matrix.
In “HPCG”, it was 13.4 PFLOPS, which was 1st place with an overwhelming difference of 4.57 times that of 2.93 PFLOPS of 2nd place Summit.
“HPL-AI”:
Evaluate the speed of solving linear equations by utilizing half-precision arithmetic (16-bit floating point) often used in AI systems.
In “HPL-AI”, it was 1.42 EFLOPS, which was 2.58 times higher than that of Summit, which was second.
“Graph 500”:
It is an index for evaluating the performance of big data processing, etc., and is evaluated by the graph search speed such as integer operation and memory access speed.
In the “Graph 500”, it achieved 70,980 GTEPS, showing a performance difference of 2.99 times compared to 23,756 GTEPS of 2nd place China / Kamui Tai Lake Nomitsu.
This is HPL-AI’s first ranking announcement.
No. 1 on the list:
It is the first time FUGAKU has achieved four crowns in the benchmark test.
Moreover, it is the fourth crown with an overwhelming difference of at least 2.58 times.
Actually, the measured value with Graph500 is the performance when about 60% of the whole FUGAKU compute node is in operation.
Just showing the scale, he showed a great distance from the second place and below.
