The Register: IBM preps AIX 5L 5.2 for October release

"The L in AIX 5L stands for Linux affinity, which means that many of the Linux APIs are supported within AIX so applications written for Linux can be recompiled to run natively on PowerPC and Power4 processors. IBM had originally intended to offer the ability to run Linux binaries compiled for Intel processors on AIX 5L, but this part of the operating system never got off the ground because of the performance penalties involved with running emulated X86 instructions on the IBM Power chip architecture.

AIX 5l V5.1 includes support for Power4 processors, 32-way symmetric multiprocessing, rudimentary static logical partitions, 256Gb of main memory, and 64-bit AIX kernel and drivers. The prior AIX 4.3 releases supported 24-way SMP and 96Gb of main memory and had support for some 64-bit APIs.

According to sources familiar with IBM's plans, AIX 5L V5.2 will have support for dynamic logical partitions - presumably only on Power4-based pSeries 690 servers, but perhaps also on S-Star PowerPC-based pSeries 680 servers."
