Newsgroups: comp.parallel From: Mike Delves Subject: ANNOUNCE: Release 2 HPF Compiler from NASL Organization: NA Software Date: 22 Apr 1997 11:58:34 GMT Message-ID: <5ji95a$h62@server1.ctc.com> N.A Software is pleased to announce that Release 2 of our HPFPlus compiler is now available. Compared with Release 1.1 it provides substantial gains in functionality: Efficiency Major code optimisations are included which improve the runtime efficiency of most codes. We have seen gains in speed of up to four times; for many codes, the single processor overheads stemming from the use of HPFPlus Release 2 are negligible. Language Multi-statement FORALL, PURE procedures, and EXTRINSIC(HPF_SERIAL) procedures are now handled. The gain in expressiveness allows serial Fortran77 and Fortran90 codes to be converted more easily. MPI is now supported providing faster message--passing on most platforms. Scalability is significantly improved under MPI. A Hostless Model is now used on most implementations. On systems which do not provide multi--tasking on individual processors, this avoids tying up one processor to handle I/O. Parallel I/O is accessible on systems which make this feasible. This includes workstation and PC clusters. The MDB Source Level HPF Debugger has been enhanced to support MPI and Hostless running. MDB makes debugging HPF as easy as debugging serial codes. With the use of the LOFT90 F77-F90 translator and HPFPlus Release 2, major Fortran77 codes can now be converted to HPF more easily. Availability HPFPlus Release 2 can be ordered now for immediate delivery for: PC clusters running Linux (PVM provided) Sun Sparc clusters running Solaris or SunOS (PVM or MPI) Meiko CS2 (PVM or MPI) IBM SP2 (MPI) For availability on other systems, or for more details, email us at nasoftware.co.uk or look at http://www.nasoftware.co.uk Prices start at 595.00 (425.00 academic) for a single user PC cluster. Upgrade prices for existing Release 1.x users are available. -- Articles to parallel@ctc.com (Administrative: bigrigg@ctc.com) Archive: http://www.hensa.ac.uk/parallel/internet/usenet/comp.parallel
