Features and benefits

Features Details Benefits
Scalar libraries The MASS scalar libraries contain an accelerated set of frequently-used single- and double-precision math intrinsic functions. Provide speedups up to 8x over the standard system library.
Vector libraries The MASS vector libraries provide increased performance by operating on a vector of arguments. They include single-precision, double-precision, and integer functions. Provide speedups up to over 35x compared to the standard system library.
SIMD libraries The MASS Single Instruction Multiple Data (SIMD) libraries are provided for SIMD architectures. They operate on SIMD vector arguments, and include single-precision, double-precision, and integer functions. Provide speedups up to 80% compared to the standard system library.
Compatible processors POWER, POWER2, POWER3, POWER4, POWER5, POWER6, POWER7, Blue Gene/L, Blue Gene/P, Cell Broadband Engine (PPU and SPU).
Supported operating systems AIX, Linux
32/64-bit mode support 32-bit mode applications are supported, as well as 64-bit mode applications on processors supporting them.
