Linux cluster development tools for 32-bit and 64-bit processor-based systems

Linux clusters now are easily affordable by any group interested in serious scientific computing. Getting hardware installed and a network up and running are just the first steps in building a cluster. The PGI CDK Cluster Development Kit contains all the software development and cluster management tools you need to get a Linux cluster running production applications. The PGI CDK includes:

• Floating multi-user seats for PGI's parallel Fortran, C, and C++ compilers for Linux. Industry-leading single-processor performance and integrated native support for all three popular parallel programming models: HPF, OpenMP, and MPI.
• Graphical MPI and OpenMP Linux Cluster debugging (PGDBG) and parallel performance profiling (PGPROF) tools.
• Pre-compiled/pre-configured MPICH message-passing libraries and utilities.
• Pre-compiled/pre-configured TORQUE resource management and batch queueing system to manage the workload and throughput on your cluster.
• Pre-compiled ScaLAPACK parallel math library.
• Optimized BLAS and LAPACK serial math libraries.
• Tutorial examples and programs to help you get your codes up and running quickly using HPF, OpenMP, and MPI messaging.
• Installation utilities to simplify the setup and management of your Linux cluster.

The PGI CDK has the features you need whether you have legacy FORTRAN 77 that relies on Cray, DEC , or IBM extensions, or you are writing modern parallel codes in Fortran 95, High Performance Fortran (HPF), or C/C++. PGI's compilers are highly optimized for Intel Pentium, Xeon and Xeon-64, and AMD Athlon/AthlonXP and Opteron workstations and servers running Linux. Parallelize your applications using MPI or use explicit HPF or OpenMP directives.

In addition to the data parallel capabilities of the PGHPF compiler, the PGI CDK package includes the PGF90 Fortran 95 compiler; the PGF77 FORTRAN 77 compiler; the PGCC ANSI C compiler; and the PGC++ ISO/ANSI-compliant C++ compiler. All of these compilers support automatic parallelization for SMP workstations using a simple compiler switch, and full native support for OpenMP directive-based SMP programming. In addition to the full suite of parallel language compilers, the PGI CDK for Linux includes the PGDBG OpenMP/MPI Cluster Linux graphical debugger and the PGPROF OpenMP/MPI Cluster Linux performance profiler. Many vendors support parallelization using simple add-on pre-processing technology, but PGI offers the only intel Pentium, Xeon, Xeon-64 and AMD Athlon/AthlonXP and 64-bit Opteron parallel compilers, debugger and profiler available with integrated parallelization support. This results is faster development, higher performance and much higher reliability for the programmer. Also, with PGI CDK there are no parallel runtime fees of any kind--the executables produced by the PGI compilers can be executed on any compatible system regardless of whether the PGI compilers are installed.

MPICH, developed at the Argonne National Laboratory, is an open source implementation of the Message-Passing Interface (MPI) standard. MPICH is a full implementation of MPI, so your existing MPI applications will port easily to your Linux cluster using the PGI CDK. The TORQUE resource manager is based on OpenPBS and includes recent improvements and extensions.
