- ===========
- NEW RELEASE
- ===========
-
- A new release of the iPSC/DASH library is now available via
- anonymous FTP from mojave.stanford.edu under the directory
- /pub/dash-msg-library.
-
- By default, the library will run with 64 virtual processors.
- (See Makefile on how to change default value or to map virtual to
- physical processors.) Please be warned that each one of the
- processes will create a mmap on your /tmp partition. So, if
- you do not have too much disk space, try not to run too many
- processes. As you probably know, mmap is not known for good
- behavior. By being too ambitious you will only end up rebooting
- your machine.
-
- A FORTRAN-to-C wrapper has been included in our latest distri-
- bution of the iPSC/DASH library. See the included sample
- makefile "makef77" for linking and loading information. However,
- certain functions supported in the C distribution are NOT
- supported in the FORTRAN version until further notification.
- These include: hsend, hrecv, forflush, cwrite and cread.
-
- In addition, the FORTRAN library has been integrated successfully
- with FORTNET, a parallel computing utility developed by the
- Daresbury Laboratory of the British Science and Engineering
- Research Council (SERC). FORTNET in turn interfaces with PAR-
- LANCE, which represents a wealth of machine-independent parallel
- numerical algorithms from major European research institutions.
- Please contact Dr. Robert J. Allan of the SERC Daresbury
- Laboratory (rja@cxa.dl.ac.uk) directly for licensing information
- on FORTNET and PARLANCE.
-
- We have received a few complaints about compiler compatibility.
- As a result, a binary copy of the library has been enclosed in
- the current distribution. Please download the files in binary
- mode to ensure 100% compatibility.
-
- We are interested in hearing from you if you have successfully
- run applications on any machine outside of Stanford or NASA Ames.
-
- Thanks very much.

- ========================================
- FORTRAN QUESTIONS THAT WE NEED HELP WITH
- ========================================
-
- (1) Can any FORTRAN expert out there teach us how to pass that
- void (*func)() to hsend or hrecv in C? We can wrap a void *func
- pointer from FORTRAN to C and then recast it. But we aren't sure
- if FORTRAN is actually passing a pointer when it is trying to
- pass a function as an argument to a subroutine.
-
- (2) Can the folks from Intel or anyone else send us some informa-
- tion about the new OSF/860 specifications?
