    with current compilers. String and character array processing, traditional loop and array SIMD Processing on IBM z14, z13 and z13s Background Companies want to quickly and efficiently processing with integer and floating point data process huge amounts of information for can all be accelerated using SIMD. Complex analytics, mobile applications, data serving and mathematical processing, algorithmic-intensive more. To cost-effectively achieve these programs, image processing applications, and efficiencies new innovative technologies are other applications can be efficiently processed needed. Vector processing and SIMD optimize with SIMD. SIMD also enables processing of a performance by processing data in parallel on new class of applications on IBM Z using ® IBM Z . analytics, mathematical optimization without requiring an offload to specialized processors. What is SIMD? Standard SIMD math and linear algebra libraries SIMD stands for Single Instruction Multiple Data. enable easier porting from X86 platforms. Unlike instructions which performs a single operation on a single data point, SIMD instructions Compilers can perform the same operation on multiple data SIMD helps you achieve efficiencies using IBM points at once. z/OS® XL C/C++ V2.1.1, IBM Enterprise COBOL 5.2 and IBM Enterprise PL/I for z/OS V4.5, for SIMD is an innovation that was delivered with applications with character or integer IBM z13® (z13) and IBM z13s™ (z13s). With SIMD manipulation. IBM z/OS XL C/C++ V2.1.1 entire arrays of data can be processed by a compilers offer new capabilities, such as single instruction enabling more efficient architecture sections, inline assembly, and high processing of data.
