....operating system or multiple processes easily. The latest release of ATOM, however, does provide this capability [8] More recent work, which builds upon the work of Eustace and Chen as described in [11] extends ATOM to study the effects of the operating system impact on cache performance [14]. Some of the limitations of this work were: 1. the operating system could only run in single user mode, 2. substantial slowdown (10 100X) was introduced, 3. portions of the OSF kernel could not be traced, 4. floating point numbers or system calls can not be used in analysis routines, and 5. ....

....traces. The slowdown when capturing traces is on the order of 10X. Adjustments to timers and system services have been made in order to account for this slowdown. The only difference is how we access the data structure in the kernel. Due to the limited space in this paper, we point the reader to [12] for a complete description of operating system tracing using ATOM. 4 PatchWrx The PatchWrx Tracing toolset was developed to capture activity of Microsoft NT workloads and kernel execution, as run on a DEC Alpha platform. The goal was to capture a rich set of traces without introducing a large ....
....(only GCC experiences a significant increase) we do see a dramatic change in the data cache miss rates. This effect is fairly consistent, independent of application. A full set of cache simulations, including results for capturing multiple programs and the operating system, can be found in [12] Next we present results for Microsoft NT 4.0 workloads, as captured by the PatchWrx tool. Note that the length of the traces that we have captured to date is only bound by the limited storage provided on our tracing system. PatchWrx allows for nearly unlimited length traces, given sufficient ....
