[mvapich-discuss] SDR or DDR

[Gilad Shainer]

The DDR or SDR is the link speed, 10Gb/s or 20Gb/s, and not the RAM.

Your HCA is SDR, with DDR you will see DDR in the tvflash -i output.

	I need to fill in the value for LINKS=_DDR_ or _SDR_

	Does anyone know how I tell whether my Infiniband cards have DDR
or SDR ram?

	 

	Also, my cards are PCI Express. For IO_BUS, I would choose
_PCI_EX_, correct?

	 

	tvflash -i command reports the following:

	 

	HCA #0: MT25208 Tavor Compat, Lion Cub, revision A0

	  Primary image is v4.7.600 build 3.2.0.110, with label
'HCA.LionCub.A0'

	  Secondary image is v4.6.000 build 3.1.0.113, with label
'HCA.LionCub.A0'

	 

	  Vital Product Data

	    Product Name: Lion cub

	    P/N: 99-00026-01

	    E/C: Rev: B04

	    S/N: TS0548X03797

	    Freq/Power: PW=10W;PCIe 8X

	    Date Code: 0548

	    Checksum: Ok

	 

	Thanks, Mike
