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. Documentation: -------------------------------- See the intro_libsci_acc man page for additional information. Modulefile: ----------- module load cray-libsci_acc 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.
