hydra2 latest C/C++/Fortran patches on 09/04/2009

To save further down time, we let hydra2 today (Fri, 09/04/2009) receive the latest round of patches for the AIX compilers, C/C++ V10.1 and Fortran V12.1.

The current AIX compilers on node hydra and the rest of the Hydra cluster remain un-patched. If no major issues surface during a user-testing period of two months, we will propagate the latest AIX compilers' patches to the rest of the Hydra cluster.

We urge the users who are developing or porting code onto Hydra to try out the AIX compilers with the latest patches on hydra2. Report to us any case where the new compiler or your code behaves in an undesired manner vs. the current compilers.

Your feedback on testing the patched AIX compilers on hydra2 would thus be very important. We will be announcing ahead of time the installation of the compiler patches to the rest of the cluster.
