OSU MVAPICH 1.2.0 b. Open MPI 1.4 c. OSU MVAPICH2 1.4 d. MPI tests 3.2 2.7 iSER: o Available on: - kernel.org: 2.6.30 and higher - RHEL5.4 2.8 NFS-RDMA o Added support for RHEL5.4, SLES10 SP3, kernel.org 2.6.25 and 2.6.30. Kernels 2.6.26 and 2.6.27 are not supported o NFS-RDMA is in Beta level =============================================================================== 3. Known Issues =============================================================================== The following is a list of general limitations and known issues of the various components of the OFED 3.5-rc2 release. 1. When upgrading from an earlier OFED version, the installation script does not stop the earlier OFED version prior to uninstalling it. Workaround: Stop the old OFED stack (/etc/init.d/openibd stop) before upgrading to OFED 3.5 or reboot the server after OFED installation. 2. Memory registration by the user is limited according to administrator setting. See "Pinning (Locking) User Memory Pages" in OFED_tips.txt for system configuration. 3. Fork support from kernel 2.6.12 and above is available provided that applications do not use threads. fork() is supported as long as the parent process does not run before the child exits or calls exec(). The former can be achieved by calling wait(childpid), and the latter can be achieved by application specific means. The Posix system() call is supported. 4. The qib driver is supported only on 64-bit platforms. 5. IPoIB: brctl utilities do not work on IPoIB interfaces. The reason for that is that these utilities support devices of type Ethernet only. 6. In case uninstall is failing, check the error log and remove the remaining RPMs manually using 'rpm -e '. 7. On SLES11.x, set allow_unsupported_modules parameter to 1 in file: /etc/modprobe.d/unsupported-modules. Without this the modules will not load. Note: See the release notes of each component for additional issues.
