Re: WLUG Meeting Feb 11th 2021! Topic: Good question!

by Jon "maddog" Hall

John, I read what Linus wrote and I think the most important paragraph is the last two. This "deficiency" in the Alpha design was not that consequential to anyone but a very small number of people, and still allowed the Alpha to be the world's fastest microprocessor for (if I remember correctly) eight years in a row according to the Guinness Book of Records. As to the little vs big endian issues, the worst part was in reading undefined data across the network. What do I mean by "undefined data"? o The union statement in "C" o The equivalence statement in FORTRAN o The Linkage section in Cobol All statements that allow you to write the same data looking at it in different ways. If you write out a "block" of Integers into a file, there is no way that a system reading that file some time later could tell if those integers were written by a little endian system or a big endian system, so the Integers would be read incorrectly. NFS made it worse....much worse, but it was bad before NFS. md On Thu, Feb 4, 2021 at 5:37 PM John Stoffel <john(a)stoffel.org> wrote: > >>>>> "Jon" == Jon \"maddog\" Hall <jon.maddog.hall(a)gmail.com> writes: > > Jon> John, > >> Yes, but I don't properly recall if the Itanium design was started > >> before AMD64 came or as a reaction to the AMD64.

dual PII/PIII motherboard of questionable origin up for grabs

by Brian J. Conway

The WPI Linux Association received a donation of a SuperMicro SUPER P6DBE dual PII/PIII 440BX motherboard (http://www.supermicro.com/PRODUCT/MotherBoards/440BX/p6dbe.htm) The original owner upgraded because it was flaky and thought the parallel port was bad, but upon buying a new motherboard found that it was his fubared sound card causing flakiness, so I'm under the assumption that this motherboard should be good or at least workable, but of course there are NO GUARANTEES. As we currently have no use for it and I'd hate to see it go to waste, get back to me if you'd like it, but please only do so if you'll put it to good use, I'd hate to see something like this go to waste. I'll bring it to the next WLUG meeting to hand off. Brian J. Conway dogbert(a)clue4all.net Geek for hire: http://clue4all.net/resume Power Mac G4 Cube. Some of us are getting laid tonight. (http://www.pvponline.com/archive.php3?archive=20010509) P.S. I'm also told the screen at POST looks a little garbled, but that's due to the latest BIOS update and performance should be unaffected.

If it does not, please let me know and I'll investigate. I believe that the Night Life program in Worcester offers a class in Linux, taught by a WLUG member. However, I don't know what Night Life's policy is regarding a student's age. In addition, The Town of Chelmsford has a Community Education program which offers Linux classes (taught by another WLUG member), but that's probably too far away for you.

Re: [Wlug] large file performance on linux

by brad noyes

All, here's a summary of what i have tried so far. I have tried using the O_DIRECT and O_SYNC flags with open(2) and i have been using a non-journalling filesystem, ext2. None of these options have yielded any better performance at the rates i'm looking for. I have not tried AIO. I don't think i can use a non 32-bit kernel on the xeons. Correct me if i'm wrong (it's happened before). As a temporary solution i created a memory filesystem, by $> mount -t tmpfs tmpfs -o size=6G /data/memory The writes are fast however i need another process to progressively move data out of the memory filesystem since i don't have enough memory to hold all 22GB of data i need. For those interested i have attached a small program which will use different options to open and profile the fwrite calls. To compile simply do $> sh ./testwrite.c $> ./testwrite -h $> ./testwrite -l 16 file.out I just wanted to keep you all updated. Thanks for all your help. I'll keep trying various ideas. I wish i could make it to the meeting to buy you all pizza for your help. Perhaps next month. Thanks, -- Brad
