There s something else going on here. I m not sure who originally analyzed the file to decide that the format was Stream-CR (although given that the analysis was done on RSX, we can probably guess :-) >On 2012-12-31 14:59, Brian Schenkenberger, VAXman- wrote: >> Johnny Billquist <bqt at softjar.se> writes: >> >>> On 2012-12-31 08:08, sampsa at mac.com wrote: >>>> Funny thing about LEGATO's INFO.TXT - my parser looks for the .BEGIN-HECNET-INFO tag and deletes all text after that. >>>> >>>> I should probably make a manual HLP file for LEGATO, Bob you OK with that? >>> >>> LEGATO's INFO.TXT have real yucky file attributes and a real yucky >>> file format. :-) (What on earth was used to produce it???) >> >> Stream_CR typically surfaces with files coming from WEENDOZE. > >Ah.

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

SIMH performance on OS X vs Linux

by jg＠jordi.guillaumes.name

El 31/12/2012, a les 16:01, Clem Cole <clemc at ccc.com> va escriure: For this reason, besides making sure the HW is that I would standardize the compiler if you can. FYI: The Intel C/C++ compiler for both Linux and OS X are the same compiler, although sometimes slightly different libraries. Tends to be a better Apples to Apples test than GCC because of some of the variations introduced into gcc by different players (plus Apple is moving away from gcc to LLVM due the silliness caused the GPL restrictions). Hmmm if I'm not mistaken, nowadays MacOS defaults to use the clang compiler... Anyway that does not justify that performance difference.
