Abacus

Abacus is a C++ metrics library. We wanted to create a library that allows us to create counters in our other libraries that:

• Are fast to increment/update
• Are fast to copy/transfer between dependencies
• Can separate hot and cold memory
• Can keep everything in one contiguous memory block

With this, you can create metrics for a library that can be carried through dependencies all the way to the top-level application like so:

|    Library    |          Dependency         |    Library    |
|       1       |            ----->           |       0       |
+-------+-------+                             +-------+-------+
        |                                             |
        |                                             |
        |  Library specific metrics                   |  Library specific
        |                                             |      metrics
        v                                             v
+-------+-------+                             +-------+-------+
