IA-64 (Itanium 2)
CAE ISVs began supporting Itanium/HP-UX in 2001 and by 2004 nearly all CAE solvers were released on Itanium2/HP-UX and Itanium2/Linux servers/clusters ("HP Integrity family"). All cluster-capable CAE applications on Itanium/HP-UX and many on Itanium/Linux use HP-MPI for message passing today.
In 2006 HP expanded our offering of Linux on Integrity to include high end Superdome servers.
x64 (Opteron/Xeon EM64T)
Virtually all CAE ISVs support x86/Linux servers/clusters and x86/Windows workstations with 32-bit versions of their applications today. Due to the compatibility between legacy x86 and new AMD and Intel x86 architectures with 64-bit extensions (e.g. x64), all these codes will run today in 32-bit mode on x64 operating environments.
In February, 2004 HP announced our entry into the 64-bit x86 platform business with ProLiant servers and EM64T workstations, and in early 2005 we announced Opteron workstations. Many native 64-bit CAE ports to x64/Linux64 are now available, and CAE releases on Windows x64 workstations are expected to emerge through 2006. Many CAE ISVs are also distributing HP-MPI in their x64/Linux clusters, enabling user-transparency and switch-independent support from this high performance MPI library. Microsoft released the Windows CCS environment for clusters in 2H 2006 and ISV applications for Windows clusters are being released now and throughout 2007.
PA-RISC
HP’s PA-8800 based C8000 workstations have been the leading UNIX workstations for CAD/CAE engineers for over a decade. All CAE solver and pre/post codes have run on PA-RISC/HP-UX since the early 1990’s. Native 64-bit versions were released soon after HP-UX 11.0 became available in 1997 and cluster versions using HP-MPI became available in the late 1990’s and early 2000’s. At the end of 2007, however, HP will stop selling PA-RISC workstations and recommends x64 windows or Linux workstations for 64-bit CAE pre and post processing and solver execution.
