cray-libsci_acc Overview

LibSci_ACC 3.3.0
================
 Release Date:
 -------------
 September 24, 2015


 Purpose:
 --------
 Cray LibSci_ACC 3.3.0 provides accelerated versions of scientific libraries
 for Cray CS, XK, and XC series systems.

 The Cray LibSci_ACC 3.3.0 release provides the following:
 - Support for NVIDIA CUDA Toolkit 7.0 on XK, XC, and CS systems
 - Support for GCC 4.9 on XK and XC systems


 Product and OS Dependencies:
 ----------------------------
 The Cray LibSci_ACC 3.3.0 release is supported on the following Cray systems:
 * Cray CS systems with GPU support on CentOS (with CUDA 7) and MVAPICH2 2.0.1
 * Cray XC systems with GPU support on CLE 5.2 UP04 (with CUDA 7)

 The Cray LibSci_ACC 3.3.0 release requires the following software products:

 For Cray XK and XC systems:
 CUDA Toolkit 7.0
 LibSci 13.0.0 or later
 MPT 7.2.5 or later
 CrayPE 2.1.2 or later
 CCE 8.3.0 and later or GCC 4.9

 NOTE: GCC 5.1 and later not supported

 For Cray CS systems:
 CUDA Toolkit 7.0
 LibSci 13.0.3 or later
 MVAPICH2 2.0.1
 CrayPE for CS
 CCE 8.3.0 and later

 Notes and Limitations:
 ----------------------
 CUDA Toolkit 7.0 from NVIDIA does not support GCC 5.x.x and therefore
 LibSci_ACC 3.3.0 for XC XK does not support building with GCC 5.x.x.

 Cray LibSci_ACC 3.3.0 supports NVIDIA Tesla K20, K40, K80 series
 accelerators in serial or multiple gpu configurations.

 LAPACK workspace calculations from other implementations or hard-coded
 values may not be compatible with libsci_acc. Workspaces reported from
 a query to the corresponding libsci_acc function should be used.

 Applications running PBLAS routines on the accelerator should set the
 environment variable MPICH_NO_GPU_DIRECT=1 to ensure correctness.

 Performance improvements can be achieved in programs calling libsci_acc
 subroutines by using pinned memory. See the intro_libsci_acc man page for
 details.

 Use of the aprun option "-cc none" to disable core affinity is strongly
 suggested to improve performance.

 This version and previous versions of LibSci_ACC are not thread-safe.

 Sample Installation instructions:
 ---------------------------------
 On CLE 5.2:
 rpm -ivh --prefix=/opt/cray cray-libsci-acc-*-3.3.0-2.201509141624.c2ce335f3498b.x86_64.rpm

 On CLE 6.0:
 rpm -ivh cray-libsci-acc-*-3.3.0-2.201509141624.c2ce335f3498b.x86_64.rpm

 The "*" in the install command represents compiler version combinations.

 To make this the default version,

 On CLE 5.2 execute
 /opt/cray//pe/admin-pe/set_default_files/set_default_libsci_acc_3.3.0

 On CLE 6.0 execute
 /opt/cray//pe/admin-pe/set_default_files/set_default_libsci_acc_3.3.0
