Parallelism Should Inspire You
We struggle to think in parallel and develop models and paradigms that imitate behavior with innate parallelism. Peer-to-peer, workpile, boss worker, consumer producer describe models for concurrent work and communication. But are these models sufficient to model the behavior of complex systems that utilize massive parallelism?
Paradoxical Threading
Some threading semantics are desirably non-rigorous. What happens when we have to define every aspect of the parallel execution of our program?
Down in the Weeds of Concurrency
Contrary to a few dozen e-mails we've received, we are not against Apple's Grand Central Dispatch. We are not against black box parallelism and we're not against single-source-single-vendor end-to-end parallelization solutions. It's just that in some cases we have unresolved questions (e.g. Grand Central Dispatch's approach to modularity), in other cases we want to believe but it's just not working for us yet.
Process Monitor v2.7: A New Release to Watch Processes and Threads in Windows
Process Monitor is a very complete advanced monitoring tool that shows and logs real-time activity for the file system, the Registry, the running processes and their threads in Windows. Yesterday, the Windows Sysinternals team made the new version v2.7 of Process Monitor available for download.
One Man's Parallelism is Another Man's Breakfast
The product was absolutely cool and the breakfast spread impressive but I still felt snookered.
All CPU Meter: A Simple Windows Gadget to Monitor Cores
All CPU Meter is a very simple sidebar gadget available for Windows Vista and Windows 7. It allows developers and users to check the microprocessor's usage and it shows an independent graph for each available logical core (hardware thread).
TMonitor: Understanding What Happens With Each Hardware Thread
TMonitor, a new tool developed by the CPUID team, offers the possibility to understand what's going on with each hardware thread (logical core) on some modern multicore microprocessors.
Snow Leopard's Grand Central Dispatch and the Gift Horse's Mouth
First a disclaimer or at the very least an acknowledgment. We are heavy consumers of Mac technology at Ctest Labs. Our Pantheon cluster boasts several fully loaded multicore Macs. We combine Macs with Sun boxes and Linux boxes in a way that makes for a very formidable cluster-based supercomputer that we call the Pantheon. So right off the bat let me say that we have much love for the Mac.
