I installed 2 adcs cards in cpu 1 slots 1 and 2 (respective S/N are 210128-11 and 210128-26) and 2 dac cards in cpu 2 slots 5 and 6 (respective S/N are 200813-74 and 200813-40).
It means that one cpu is responsible for adc while another one for dac however Aso-san told us that the manufacturer confirmed that every PCI-e slot should be able to communicate with all cpus so we will have to investigate a bit the BIOS.
The dolphin card is installed on the cpu 2 slot 8.
We are also supposed to install the myrinet connection but it seems we don't have more card with SFP connector so I'm guessing we will connect through ethernet to the myrinet switch.
With the 2 adc and 2 dac cards we have 128 channels available.
