I've been running Mersenne computations on various machines for a longish time.
This summer I switched from the manual method to the Primenet server. All
under OS/2. I'm currently using:
Thu 10-29-1998 13:32
[D:\MERSENNE]primeos2 -v
Mersenne Prime Test Program, Version 16.3.2
OS/2 - EMX version 3.1
Just recently I decided (in order to have a compuational environment on my
machine that is the same as my students at UIC are using) to install Boot
Manager with OS/2 Warp 4 and Windows 95 on one of my machines. I had the bright
idea: install the mersenne stuff in one directory on a drive shared by OS/2
and Win95 (taking advantage of the differently named executables: PRIMEOS2.EXE
and PRIME95.EXE) and autostart the appropriate one from each operating system,
with them sharing the Pxxx, Qxxx etc files When I tried it, Win95
picked up the computation that OS/2 was doing when I booted it, but when I went
back to OS/2, the partial computations were lost. The results.txt file is:
[Thu Oct 22 10:35:42 1998]
Self-test 320 passed!
[Thu Oct 29 12:37:02 1998]
Error reading intermediate file: p6258701
Renaming intermediate file q6258701 to p6258701.
Error reading intermediate file: p6258701
(Being a strong believer in Murphy's Law, I had made a backup of the directory
before I tried this, so all was not lost.)
The FAQ says that the Windows and linux versions are compatible, and I
understood that the OS/2 version a re-compilation of the linux version. (I'm
using the version
Thu 10-29-1998 14:47
[D:\MERSENNE]primeos2 -v
Mersenne Prime Test Program, Version 16.3.2
OS/2 - EMX version 3.1
of the OS/2 version; I don't have the exact version of the Windows version
(it's too much trouble to re-boot Windowss at the moment) but it was downloaded
on10/14/98)
Suggestions?
