SDRGetObjects Adapter css_type

SP_Switch2_Adapter indicates that you are using SP Switch2.

Use these values to configure the

IBM High Performance Switch (HPS) support

Tasks of a parallel job running in US mode use the IBM pSeries High Performance

Switch (HPS) exclusively for communication. HPS resources are referred to as network

table windows. For US jobs to run, network table windows must be allocated ahead of

the actual application startup.

You can run US jobs through LSF control (Load Leveler (LL) is not used). Job execution

for US jobs has two stages:

Load HPS network table windows using ntbl_api HPS support via The AIX

Switch Network Interface (SNI)

Optional. Start the application using the POE wrapper poe_w command

IP jobs do not require loading of network table windows. You just start poe or poe_w

with the proper host name list file supplied.

Starting a parallel job on a pSeries HPS system is similar to starting jobs on an

SP Switch2 system:

Load a table file to connect network table windows allocated to a task

Launch the task over network table windows connected

Unload the same table file to disconnect the network table window allocated to the

task
