Re: [Pharo-users] What can we look forward to in 2017?

by horrido

You've inspired me to consider a new subproject. It's tentatively called "Smalltalk Showcase" (although I'll try to come up with a better name) and it will present a series of stories about Pharo/Smalltalk developments that demonstrate the incredible versatility and usefulness of Smalltalk. (It doesn't have to be Pharo, but I'll be pleasantly surprised if there are cool developments in Squeak, Cincom, Dolphin, GNU, etc.) Here's an open call to Pharoers (and Smalltalkers) everywhere: Submit a favourite project, including a URL to a website or repository that shows the project in the best light, as well as an "abstract" that nicely summarizes what the project is trying to accomplish. I'll select the ones that are most interesting and do work-ups on them. If necessary, I'll query for more details in an email reply. Send all submissions to: richard.eng(a)outlook.com Most appreciated. By the way, the first story will be on Grafoscopio. -- View this message in context: http://forum.world.st/What-can-we-look-forward-to-in-2017-tp4926791p4926986… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

I can try that: I've some 48-core 500+ GB RAM boxes around at the moment. If someone can make me a test script, can run it.

Sure eventually, but you don't run more than a 2 or so per core so that'll never be a problem.

In a dual > core server. That's barely a server, most laptops these days have more cores. Rent a virtual server with a dozen or more cores, then you can run a few images per core without the idle mattering at all and run 2 dozen images in total per 12 core server. Scale by adding cores and ram allowing you to run more images per box; or scale by running more boxes, ultimately, you need to spread out the load across many many cores. -- Ramon Leon

In my case I served up to 20 concurrent users (out of ~100 total) with only 5 images. Plus another two images for the REST API. In a dual core server. Regards. Esteban A. Maringolo
