Hello, I'm interested in how the different versions behave and relate to each other. Have an app that is well suited to hugepages and has straightforward linking. This app already supports creating it's own work areas in hugepage shared memory segments. Looking to get as much code and malloc into hugepages as possible without changing anything.
The app links with 'libhugetlbfs' and works under CentOS 5.8 with kernel 2.6.18-308.el5. A debug trace shows code segments being copied to huge page memory successfully and 'pmap -x' shows them as "deleted" (really hugepages flag, bug in pmap). So that's great and I'm quite happy. What I'm wondering is 1) will higher-version 'libhugetlbfs.so' libraries work ok such that binaries linked on this system with 1.3 will run properly on newer distros and kernels such as CentOS 6.2 with 2.12? 2) if (1) is true, will newer features such as transparently mapping anonymous segments in hugepages work automatically in this case? Or is a relink on the newer system required? 3) is it possible to build a current version of 'libhugetlbfs' and utilities on the older RHEL 5.8 distribution to get the benefit of the utilities that have been added subsequent to version 1.3? Or will it break due to various incompatibilities? I have built and installed binutils 2.22 in /usr/local if that makes any difference. I'm hoping someone might know the answers to these questions already, without exerting effort. No problem if the answer is "unknown" or "undefined".
