I am interesting in possibility of immediate completion for just BMI_post_recv and other BMI recv functions. I can implement immediate completion for my bmi method but i am not sure that generic BMI interface supports it.

I can't speak for all the methods, but the MX method does not support any immediate completion for sends or recvs due to potential races in the implementation. I do not think the IB method allows it either but I defer to others. Scott
