Taiwania (traditional Chinese: 台灣杉; simplified Chinese: 台湾杉; pinyin: Táiwān Shān) is a supercomputer series in Taiwan owned by the National Applied Research Laboratories.^[1]

The supercomputer was activated on 9 May 2018 after a two-year program to establish it with a cost of NT$430 million.^[1]

In April 2023, it was unveiled that Taiwania 1 itself will be retired and replaced by Taiwania 4.

The Taiwania 1 Supercomputer has a memory of 3.4 petabytes with a maximum speed of 1.33 quadrillion FLOPS.^[1] The hardware takes up a total area of 33 m².^[2] Taiwania 2 has a maximum speed of 9 PFLOPS.

Taiwania 3 is one of the supercomputers made by Taiwan.^{[6][7][8][9][10][11][12][13][14][15][excessive citations]} and also the newest one (August, 2021). It is placed in the National Center for High-performance Computing^[16] of NARLabs. There are 50,400 cores in total with 900 nodes,^[17][15] using Intel Xeon Platinum 8280 2.4 GHz CPU (28 Cores/CPU)^[15][18] and using CentOS as Operating System.^[19] It is an open access for public supercomputer.^[20][21] It is currently open access to scientists and more to do specific research after get permission from Taiwan's National Center for High-performance Computing.^{[17][22][23][15][24]} This is the third supercomputer of the Taiwania series. It uses CentOS x86_64 7.8 as its system operator and Slurm Workload Manager as workflow manager to ensure better performance. Taiwania 3 uses InfiniBand HDR100 100 Gbit/s high speed Internet connection to ensure better performance of the supercomputer. The main memory capability is 192 GB. There's currently two Intel Xeon Platinum 8280 2.4 GHz CPU (28 Cores/CPU) inside each node. The full calculation capability is 2.7PFLOPS.^[25] It is launched into operation in November 2020 before schedule due to the needed for COVID-19.^[10][23][26] It is currently ranked number 227 on Top 500 list of June, 2021^[19] and number 80 on Green 500 list.^[27] It is manufactured by Quanta Computer, Taiwan Fixed Network, and ASUS Cloud.^{[19][22][28][29][30]}
