[vwnc] FW: VisualWorks Multithreading

Stew MacLean

A simple solution would be to fork multiple images and use OpenTalk (say) to control them.

 

I’ve used the Server Smalltalk framework of VisualAge to build a middleware solution based around a Controller ->* Master ->* Slave architecture.

 

Each image is a separate OS process and so can have its own core.

 

Cheers,

 

Stewart

In the Cincom Smalltalk Roadmap 2008 i saw the next:

Research: Leverage Multi Core
What: Make it easier to leverage multi-core computer
How: research & consider different approaches
Why: Taking advantage of ubiquitous multi-core computers is attractive

Are there any news about this topic?

Thanks

Stewart,

 

We have several cases of bulk-testing that follow this pattern.  We run a VW7.6 version of our VW5i client headless and use OpenTalk to implement master/slave techniques.  However, we’ve found that Opentalk saturates at about 80 slaves.  We’re looking at trying multi-tiered arrangement:  a master controls no more than 10 slaves, but a master could really be an intermediary:  a slave to a “higher” master and an overseer to other slaves.  With no trouble we can run a four-tier solution for 1000 clients, which is about 30% more than we need for our testing.

 

Cheers!
