[mvapich-discuss] MPI blocking mode progress with 10GbE/ iWARP

[Ken Cain]

Hello,

I am investigating if it will be possible to achieve blocking mode 
progress (not polling) using an MPI library on a 10GbE/iWARP cluster. 
The MVAPICH2 library parameter MV2_USE_BLOCKING describes what I am 
looking for, but I believe it applies only to the Gen2 InfiniBand 
transport. Is this true? Is blocking mode progress being considered for 
inclusion in the Gen2-iWARP transport in a future MVAPICH2 release? How 
difficult (or reasonably possible) is this to do by modifying the 
Gen2-iWARP transport source code, either on my own or by the MVAPICH2 
team? Is there an inherent problem unique to 10GbE?

I'm making some assumptions with my questions above. One for example is 
that MVAPICH (VIADEV_USE_BLOCKING) is not a candidate solution because 
MVAPICH does not run on 10GbE/iWARP clusters. Perhaps I am wrong with 
this assumption?

Thank you,

-Ken
