Process Lasso v9.2 has been released! This version adds a Dark Mode theme and has considerable other refactoring of the GUI internals. You can enable Dark Mode by right-clicking on the graph to rotate between the 3 available color themes of Light, Dark, and Custom. Alternatively, you can select it by way of the ‘View […]

Our Coreprio project, an application to optimize performance of the AMD 2970/2990wx CPUs under Windows, is now open source under the MIT license. Visit the repository here. The release of the source coincides with v0.0.6.3 of Coreprio, which includes some important refactoring. As a reminder, you can support my efforts here at Bitsum by purchasing […]

Overclocking is so pervasive that CPU, RAM and motherboard manufacturers cater to it. Modern CPUs are smart enough to self-throttle if they reach a critical temperature, making it safer than it once was. Further, power-saving technologies such as core parking and frequency scaling help resist thermal build-up. Given this, you can probably get away with […]

Process Lasso v9.1 has been released! This new version offers several enhancements over the last v9.0 build and a new feature called the Instance Balancer. Instance Balancer Other Improvements Other product improvements include a better looking graph legend with numerical readings, smoother listview refreshes, bug fixes and a few areas of refactoring. We continue to […]

Coreprio has been updated to allow for inclusion and exclusion patterns (list of applications to target). These apply to all features of Coreprio. Wildcards are allowed. The console mode utility allows these as well, via the new ‘–inclusions’ and ‘–exclusions’ parameters. Since Coreprio’s Dynamic Local Mode works best for applications that do not put a […]

Process Lasso now supports and displays the processor group(s) an application’s threads are running on. We wrote about processor groups a while back. They exist to allow for systems with more than 64 logical CPU cores. In Process Lasso, we refer to Processor Groups as ‘CPU Groups’. By default, an application’s threads are assigned to […]
Read more Coreprio is Bitsum’s custom implementation of AMD’s Dynamic Local Mode. It is more configurable than AMD’s implementation, allowing the user to set the prioritized affinity, thread count and refresh rate. History When the high core count ThreadRipper 2990wx and 2970wx were developed, AMD had to make due with the 4 memory channels available in the TR4 […]

As of Process Lasso v9.0.0.522, NUMA nodes have been added to the CPU affinity dialogs. This is part of an on-going effort to improve manageability of high core count systems.

UPDATE: Bitsum is testing our own Dynamic Local Mode implementation – See this forum thread for more information. Here at Bitsum we’ve been closely following the AMD Threadripper 2nd gen releases. As has been well reported on tech sites, the core heavy 2990wx and 2970wX have an unusual configuration where only 2 of the 4 dies […]

TL;DR – Microsoft hacked in support for more than 64 logical CPU cores by adding ‘processor groups’. Unless an application is written to take advantage of multiple processor groups (group aware), its threads will be scheduled to only a single processor group. See our new groupextend project to enable group unaware apps to make full use […]
