Hello,


About modelizations and detection of race conditions and deadlocks in parallel programming..

I have just taken further a look at the following project in Delphi called DelphiConcurrent by an engineer called Moualek Adlene from France:

https://github.com/moualek-adlene/DelphiConcurrent/blob/master/DelphiConcurrent.pas

And i have just taken a look at the following webpage of Dr Dobb's journal:

Detecting Deadlocks in C++ Using a Locks Monitor

https://www.drdobbs.com/detecting-deadlocks-in-c-using-a-locks-m/184416644


And i think that both of them are using technics that are not as good
as analysing deadlocks with Petri Nets in parallel applications ,
for example the above two methods are only addressing locks or mutexes
or reader-writer locks , but they are not addressing semaphores
or event objects and such other synchronization objects, so they
are not good, this is why i have written a tutorial that shows my methodology of analysing and detecting deadlocks in parallel applications with Petri Nets, my methodology is more sophisticated because it is a generalization and it modelizes with Petri Nets the broader range of synchronization objects, and in my tutorial i will add soon other synchronization objects, you have to look at it, here it is:

You have to get the powerful Tina software to run my Petri Net examples inside my tutorial, here is the powerful Tina software:

Also to detect race conditions in parallel programming you have to take a look at the following new tutorial that uses the powerful Spin tool:

This is how you will get much more professional at detecting deadlocks and race conditions in parallel programming.


Thank you,
