SIMH performance on OS X vs Linux

by sampsa＠mac.com

3.7-1 on OS X, 3.9 on the Linux ones - might explain the difference. Ohhhh, just did a 'file' on the binary I've been using (it worked so didn't feel the need to compile a new one): bash-3.2$ file simh-vax simh-vax: Mach-O executable i386 In any case, I don't mind the overhead of the small Linux VM underneath them and they will soon all be on a large-ish server in a colo rack as I sell my apartment.

I thought there was a way to get DUMP to dump the raw blocks in the file and bypass RMS completely, but I can't find it anymore. As I remember, on RSX it's fairly easy to bypass RMS and read the raw blocks in a file. In fact, RMS is technically optional on RSX, so it's not uncommon to do so. On VMS, however, RMS is always there and it's not that easy to read a file without it. Vaxman can tell me if I'm wrong, but I think you have to resort to logical I/O in order to bypass RMS, which would require LOG_IO privilege. The default DECnet account doesn't have that, so I'm not sure how the FALSERVER would even be sending raw blocks from the file to RSX. Bob
