[9fans] 9grid?

[Don A. Bailey]

Is 9grid still around? Has much progress been made on the viability of 9grid as a production resource in the past few years? Lots of the web data is down, so I'd love to hear from anyone using/working on 9grid resources?

Thanks,

D

That name has referred to at least two, possibly three,
distinct and unrelated projects. I don't believe any of
them are still ongoing. I also don't think any of them
were aimed at becoming what i'd call a "production
resource". What is it you're looking for?

[Don A. Bailey]

I only really considered one project to be substantial. That may be unfair. It was the one that LANL/UCal were involved in. 

I'm interested in the code for managing grid nodes and delegating tasks. 

Best,

D

Real code? talk to charles.

Or now that Go works, you could look at some of those packages.

Go embeds parallel/grid functionality now instead of just lightweight thread execution? Which packages would you point me at?

Thanks,

I would avoid using Go on Plan 9 right now for anything production
because it has issues when using many concurrent tcp connections. If you
do want to use Go, stick with reading and writing files, and let 9P do
it's thing.

I haven't had any problems with Go on other platforms (FreeBSD and Mac
OS X) except for CPU use sometimes and scheduling of goroutines. Both
you can kinda work around.

Does Go have issues in general with TCP connections, or is this a Plan 9 specific issue?

Dear Don A. "D" Bailey, CEO/Cofounder:

You should probably harass the Go people about this.

Cool, thanks. I appreciate the response.

Thankfully, we are very well versed at tuning the Plan 9 kernel. I'll take your advice and develop the benchmark. 

Is your code concealed per work on NxM? Just curious as NxM seems to solve (in what little I know about it) some of the issues we are trying to solve with Go+Plan 9.

I'd post the code for the server I wrote, but it was written as part
of work so I can't. Still, it's not hard to put together a server
which responds only to a GET.

the limit is 1024 for a terminal, and 4096 for a cpu server.
if you get a failure at a lower number, then it's not because
of concurrent connections, but something else.

i know the original nix tcp code had trouble with zero-window
probes. i'm not sure if the same was ever true of the distribution.

Haha, it's good to know the caustic wit of 9fans hasn't changed in the twelve years I've participated in it. Screen names change, but trolls will always persist.

If only Joseph Campbell were around to accurately define this lot. I think he'd get a bigger kick out of 9fans than he did the Grateful Dead. Well, maybe not. But close, I'm sure.

Unlike your desire to look at code? Why have you suddenly begun asking
questions that can easily be answered by opening source files? Are you
under coercion? Are you sending us a signal?

What happens when it fails? /sys/src/9/ip/ip.h:/Nchans isn't that low.
Do you get the "garbage collecting Convs" message from the kernel?

If you have stack traces or profiles, please post them on golang-dev
or send them directly to me. I'll try to get any bugs fixed promptly.

This goes for any other bugs encountered using Go on Plan 9.

Cheers,
Anthony

tcp uses scalednconv() which is basically Nchans*4.
