[mvapich-discuss] How to use MVAPICH with different Service Level in Infiniband Virtual Lane?

[Kihang Youn]

Hello,

I am searching the option to apply different service level(SL) in Infiniband communication.
For example, In Intel MPI, the environmental variable named  "DAPL_IB_SERVICE_LEVEL" can change the SL.
I found an evironment variable "MV2_DEFAULT_SERVICE_LEVEL" in user guide.
But, In the manual, "MV2_DEFAULT_SERVICE_LEVEL" is related RoCE priority service level.
I am not sure that the option can change "Infiniband Service Level".
Please let me know the option is that I look for.

Thank you,
Kihang
