The modern software trace recording, visualization and analysis tools such as Process Monitor, Xperf, WPR and WPA provide stack traces associated with trace messages. Consider stack traces as software traces we have, in a more general case, traces (fibers) bundled together on (attached to) a base software trace. For example, a trace message, that mentions an IRP can have its I/O stack attached together with thread stack trace with function calls leading to a function that emitted the trace message. Another example is association of different types of traces with trace messages such as managed and unmanaged ones. This general trace analysis pattern needs a name so we opted for Fiber Bundle as analogy with a fiber bundle from mathematics. Here’s a graphical representation of stack traces recorded for each trace message where one message also has an associated I/O stack trace:

For some time I was struggling with finding a good name for memory dump and software trace analysis activities. The name Memoretics I use for the science of memory dump analysis (that also incorporates software traces) seems not so good to describe the whole practical activity that should be transparent to everyone in IT. Fortunately, I timely understood that all these activities constitute the essence of software diagnostics that previously lacked any solid foundation. Thus, Software Diagnostics Institute was reborn from the previous Crash Dump Analysis Portal. This institute does pure and applied research and scientific activities and in recent years was funded mainly from OpenTask publisher and recently from Memory Dump Analysis Services. The latter company also recognized that the broadening of its commercial activities requires a new name. So, Software Diagnostics Services was reborn:
The First Comprehensive Software Diagnostics Service

When depicting trace analysis patterns I used two-dimensional diagrams based on CDF (ETW) traces such as this one for a bifurcation point:
While working today on a new pattern I needed a new expressive way to graphically illustrate the same idea of trace bifurcation points but without too much drawing. Traces from particle chambers and scattering diagrams came to my imagination after draw the first few diagrams illustrating bifurcation points:
Time directional arrow end can be omitted:
Trace variation after a bifurcation point can be indicated by angle partition:
The case when a variation also happens before is illustrated on this diagram:
and the case with several bifurcations:
Are N-bifurcations like on the diagram below possible?
Yes, they are, if the course of execution depends on some non-binary trace message parameter such as a loaded module that implements a required interface differently.

In a week this short full color book should appear in online bookstores:
- Title: Software Narratology: An Introduction to the Applied Science of Software Stories
- Authors: Dmitry Vostokov, Memory Dump Analysis Services
- Description: This is a transcript of Memory Dump Analysis Services Webinar about Software Narratology: an exciting new discipline and a field of research founded by DumpAnalysis.org. When software executes it gives us its stories in the form of UI events, software traces and logs. Such stories can be analyzed for their structure and patterns for troubleshooting, debugging and problem resolution purposes. Topics also include software narremes and their types, anticipatory software construction and software diagnostics.
