Abstract	card. Each of the IX bricks has 12 PCI-X~slots and an 109 card (the base 10). 1 Since December 2002 the Naval Research Using alpha software, NRL started operating the Laboratory (ARL) has been evaluating an Altix 3000, the Altix as a single image 128 processor system, the first site newest high performance computing system available outside of SGI to run a system that lirge as a single from Silicon Graphics, Inc. (SGI). The Altix is a image. The system was accepted and opened up to early departure from the previous products from SGI in that access users in July 2003. At this time, the Altix was instead of using MIPS processors and the IRIX operating running OpenAFS 1.2.11 natively letting the user's home system, the Altix uses the Intel Itanium IA-64 processor directory on the Altix be the same as tieir home on the and SGI ProPack (based on Linux Red Hat) operating other HPC resources at NRL. Connections to the network anwereIviaoHac622bATM cardsiand a dadditio alt339 system. The Altix still has the brick concept of system were via HE 622 ATM cards and an' additional 339 configuration and the SGINUMAlinkfor the inter-module gigabytes of high speed disk space was available for the network for the shared memory. The Altix runs under a direct I/O of data to the Altix. Users could submit their single image of the operating system and supports jobs via the PBS Pro 5.1 queuing system and the Intel parallel programming through OpenMP, MPI, CoArray, Fortran and C/C++ compilers were available for FORTRAN, and an automatic parallelizing compiler. compiling and linking users codes. In August, the Various codes have been evaluated with respect to their processors were upgraded to 1.3 GHz Itanium II ease of portability and their performance on the Altix as processors. compared to other high performance computers. 2.
