Status of my Work with GCC
by Nicholas Krause 07 Jan '20

07 Jan '20

Greetings All, I've sure some of you are aware of my work with the GCC folks but if not I've coordinating and figuring out how to scale/implement multi-threading in GCC to support it. In addition I've in contact with the LLVM side to see if there interested as well. I may be at the next meeting as I believe some of had unanswered questions about a) my work or b) compilers in general. My wiki article will be posted soon after I do final edits and heard back from some people, Nick P.S. I'm attaching a rather rough draft as I've rereading it carefully for grammar and issues but if people want to read it earlier that's fine with me. The ideas and writing may change but its a earlier draft.

Remove drive, system won't boot
by Evan Leibovitch 04 Jan '20

04 Jan '20

Hi again, Sorry for two system problems over the holidays, but this last one truly has me stumped. Last week I had a problem trying to back up files onto a large drive using a USB enclosure. This week I've tried to complete the install, and of course it could not go without problems.... The config is: SDD with /boot and / HDD1 with /var, /home and swap HDD2 has one data partition HDD3 has one data partition I am trying to replace HDD2 with HDD3. HDD3 installs and mounts just fine. But if I unplug HDD2, the machine refuses to boot. Taking it to recovery mode eventually ends up in a hardware freeze. Plugging it back in goes to a normal boot, even though the HDD2's partition is no longer mounted to anything. I've tried to eliminate the BIOS as a source of the problem, have updated it to the latest version and ensured that the disk-to-be-removed is not seen in any BIOS configurations. I attach the one log file I am able to capture, since it freezes before mounting /var. As best as I can tell the freeze happens during the point of the bootup where it's running fsck on the drives. It may be looking for the removed HDD2 but I don't know where it's remembering to look for it. HDD2 is no longer in /etc/fstab and I searched in vain for any instance of the UUID of HDD2 in either /boot or /etc. Any suggestions? -- Evan Leibovitch, Toronto Canada @evanleibovitch or @el56

Open CAPI Standard
by Nicholas Krause 03 Jan '20

03 Jan '20

Greetings, I mentioned this to some of you at the meeting in December but IBM and others are working on creating a new standard to replace PCI express and some of its limitations called Open CAPI. The current versions is as fast as NVLink at 50GBs in a x16 lane from memory which future versions being able to hit over 100GBs in the same lane speed and 250ms latency guaranteed as compared to the 500ms to 750ms in PCI express. This is a link:https://opencapi.org/ to anyone who wants to read the spec, through you will have to give them a email and I believe where you work. Currently POWER is the only real architecture supporting it through or NVlink for that matter. Nick

The Computer Chronicles - UNIX (1985) - YouTube
by James Knott 03 Jan '20

03 Jan '20

I used to watch this series when it was on Ch 23, Buffalo, then the 2nd PBS station. Since it wasn't carried on Rogers, I had a small set top UHF antenna, which worked very well sitting in the window of my 14th floor apartment, facing south from the Port Credit area of Mississauga. https://www.youtube.com/watch?v=0DdoGPav3fc

Rust intro tonight (free)
by D. Hugh Redelmeier 03 Jan '20

03 Jan '20

I don't know anything about General Assembly but they are hosting a "Practical Introduction to Rust" at 18:30 Thursday (today). You need to register. <https://generalassemb.ly/education/practical-introduction-to-rust/toronto/9…> It is given by a Blad Filippov of Mozilla Preparation: "Bring a laptop with a code editor installed. Bonus points for installing the Rust toolchain: https://rustup.rs/" I'm going to go. I assume that the text editor I use qualifies as a code editor.
