I never completely grasped this myself, and the IB code ended up like that by trying all the combinations until the core dumps went away.I think it is this, but Phil may correct me: when you do an active lookup, via BMI_addr_lookup, it is that function itself that builds the new reference for the address (alloc_ref_st()). The device, as invoked by the addr_lookup method function, does not need to call back into BMI to tell it to allocate the address it is currently working on for the client. On the other hand, when the server happens to find out about a new address due to passive activity, in our case listening on a TCP socket for new connections, the BMI layer doesn't know about the address. The device must use the callback function to tell BMI to allocate the reference structure. If you come up with a nice way to understand and comment that, let me know and I'll stick it here and there in the code. Better yet, send a patch for bmi.c that will let us all know. -- Pete
Hi Pete, Thanks. I doubt that I understand it enough to comment it. :-) Scott _______________________________________________ Pvfs2-developers mailing list [email protected] http://www.beowulf-underground.org/mailman/listinfo/pvfs2-developers
