top three china HPC systm in china hpc top100 and topc500 2011

the Top three sites  from china hpc top100 2011 and top500 2011

Tianhe-1A:天河一号

• top500 (2nd)
• NUDT YH MPP, 7168 x2 xeon x5670 6C 2.93Ghz, 7168 NIVIDIA M2050
• Total core= 7168x(2x6+14)=186368 (agree with top500 list)
• Rpeak=7168x(2x6x2.93x4+14x32x1.15)=4701061 (top500=4701000)
• top100(1st)
• NUDT YH MPP, 7168 x2 xeon x5670 6C 2.93Ghz, 7168 NIVIDIA M2050 and 2048 FT-1000, 8C and 1GZ (it was list as Hex Core, a misprint)
• Total core= 7168x(2x6+14)+ 2048x8=202750 (agree with top100)
• Rpeak=470100, mean that it does not include FT-1000 in Rpeak and linpack
• It seems that to highlight china own FT-1000 chip it need to be included in top100
• we all know that it is not easy to run linpack in a mix-CPU environment so it make sense not to include FT-1000 in linpack

Nebulae:曙光星云

• top500 (4th)
  
• Dawning TC6300 Blade, 4640 x2 xeon x5650 6C 2.66Ghz, 4640 NIVIDIA C2050
• Total core= 4640x(2x6+14)=120640 (agree with top500 list)
  
• Rpeak=4640x(2x6x2.66x4+14x32x1.15)=2982964 (top500=2984300)
• top100(4th)
• Dawning TC6300 Blade,2560 x2 xeon x5650 6C 2.66Ghz, 2560 NIVIDIA C2050,but for calculation to match the reported total core cout the total blade is only 2016
• Total core= 2016x(2x6+14)=52416(agree with top100 list)
  
• Rpeak=2016x(2x6x2.66x4+14x32x1.15)=1296046 (top100=1296320)
• so between top100 and top500 report Nebulae system almost double in size
• if one look at the Top500 site Nebulae system did not change  between 06/2010 and 11/2011
• One just wondering why  Nebulae NEED to report few system for China HPC100

SUNWAY Blue light:神威蓝光

• top500 (14th)
  
• SUNWAY bluelight MPP shenwei SW1600 16 core 975Mhz
• Total core= 8575x(16)=137200 (agree with top500 list)
  
• Rpeak=8575x(16x.975x8)=1070160 (agree with top500 list)
• top100(2nd)
• SUNWAY bluelight MPP shenwei SW1600 16 core 975Mhz
• Total core= 8575x(16)=137200 (agree with top100 list)
  
• Rpeak=8575x(16x.975x8)=1070160 (agree with top100 list)
• SW1600 is 16 core CPU that use 5x5 crossbar to connect 4 (4core) group and IO system that support PCI-E and ge NIC on chip and mgmt channel
• each 4 core group support DDR3/1333 memory channel/bank
• PCI-E support 8x5 gbps
• each system bd has two CPU, it is not know how these two CPU connected
• 1U system has 4 system bd, I ASSUME that each system bd has its own QDR connection
• SUNWAY use  324 port and 256 port IB switch
• 324 is 3 layer COS network of 3x9 of 36 port chip
• 256 is two layer fat tree, I could not understand the network diagram
• Due to the high density of CPU in 1U, system use water cooling
• overall  very impressive system with only 9 rack

May be by next year all these systems will use China's own chip

• godson
• shenwei

To replace these Xeon chip and NIVIDIA with GODSON or SHENWEI will cost  money , but  Today China does not have shortage of MONEY
