Have any other LND authors (either at Sun or elsewhere) noticed recent Lustre versions passing iovs with non-page-aligned middle elements down to the LND layer? We''ve always seen plenty of misaligned start/end elements, but prior to 1.6.3 we never saw it with middle elements. We were advised that this would never be the case, and some code was written based on that assumption. Now we do see this behavior from lnet - always associated with large/complex "ld" invocations while building programs, oddly enough. This is a little non-trivial to deal with in our LND for the SiCortex fabric interconnect, and is likely to remain a performance issue even with code in place to handle it. Have any of the folks working on other LNDs hit this?
