New Language Features

The major new features for this release are as follows:

• ESTABLISHQQ library routine

  Lets you specify a routine to handle Run-Time LIbrary (RTL) errors. For more information, see ESTABLISHQQ.

• ASSUME directive

  Provides heuristic information to the compiler optimizer. For more information, see ASSUME.

• DECLARE SIMD directive (OpenMP* API)

  Generates a SIMD procedure. For more information, see DECLARE SIMD.

• PROC_BIND clause for PARALLEL directive (OpenMP* API)

  Lets you specify a method for mapping the threads in the team to the "places" in the current partition. For more information, see PARALLEL Directive (OpenMP* API).

• SIMD directive (OpenMP* API)

  Requires and controls SIMD vectorization of loops. For more information, see SIMD Directive (OpenMP* API).

• DO SIMD directive (OpenMP* API)

  Specifies a loop that can be executed concurrently using SIMD instructions. For more information, see DO SIMD.

• PARALLEL DO SIMD directive (OpenMP* API)

  Specifies a loop that can be executed concurrently using SIMD instructions. It provides a shortcut for specifying a PARALLEL construct containing one SIMD loop construct and no other statement. For more information, see PARALLEL DO SIMD.

• TARGET directive (OpenMP* API)

  Creates a device data environment and executes the construct on the same device. This directive only applies to Intel® MIC Architecture. For more information, see TARGET.

• TARGET DATA directive (OpenMP* API)

  Creates a device data environment for the extent of the region. This directive only applies to Intel® MIC Architecture. For more information, see TARGET DATA.

• TARGET UPDATE directive (OpenMP* API)

  Makes the list items in the device data environment consistent with their corresponding original list items. This directive only applies to Intel® MIC Architecture. For more information, see TARGET UPDATE.

• DECLARE TARGET directive (OpenMP* API)

  Specifies that named variables, common blocks, functions, and subroutines are mapped to a device. This directive only applies to Intel® MIC Architecture. For more information, see DECLARE TARGET.

• TASKGROUP directive (OpenMP* API)

  Lets you specify a wait for the completion of all child tasks of the current task and all of their descendant tasks. For more information, see TASKGROUP.

• DISTRIBUTE directive (OpenMP* API)

  Specifies that loop iterations will be executed by thread teams in the context of their implicit tasks. For more information, see DISTRIBUTE.

• TEAMS directive (OpenMP* API)

  Creates a group of thread teams to be used in a parallel region. For more information, see TEAMS.

• Format !DIR$ PREFETCH *

  The format !DIR$ PREFETCH * is now allowed for the PREFETCH directive. For more information, see PREFETCH.

• FMA and NOFMA directives

  FMA tells the compiler to allow generation of fused multiply-add (FMA) instructions, also known as floating-point contractions. NOFMA disables the generation of FMA instructions. For more information, see FMA.
