Applies to AQTime 8.80, last modified on June 13, 2019

As the System Requirements topic states, AQTime can operate on computers that include any of the following processor models if the processor provides appropriate performance:

  • Intel Processors
    • Processors of the Intel Core family (Intel Core i7, Intel Core 2 Duo, Intel Core Duo and others)
    • Intel Xeon and Intel Xeon MP

      Some counters are not supported on the Intel Xeon multi-core processors with the Hyper-Threading technology, for instance, on Intel Xeon Duo Core processors with hyper threading. See below).

    • Intel Pentium II
    • Intel Pentium III
    • Intel Pentium 4 (including Intel Pentium 4 supporting Hyper-threading Technology and Intel Pentium 4 Extreme Edition supporting Hyper-Threading Technology)
    • Mobile Intel Pentium 4
    • Intel Pentium Extreme Edition
    • Intel Pentium D
    • Intel Pentium M
    • Intel Celeron
    • Intel Celeron D
    • Intel Celeron M
  • AMD Processors
    • AMD Phenom
    • AMD Athlon 64 FX
    • AMD Athlon 64 X2 Dual-Core
    • AMD Athlon 64
    • AMD Sempron
    • AMD Opteron
    • AMD Athlon XP
    • AMD Turion 64 X2 Mobile Technology
    • AMD Turion 64 Mobile Technology
    • AMD Athlon 64 for DTR
    • Mobile AMD Athlon 64
    • Mobile AMD Sempron

Using some of the processor models mentioned above imposes certain limitations on AQTime’s functionality. These limitations mean that particular profiler counters are not available for these “exclusive” processor models. The Intel Pentium 4 and Intel Pentium D processors are free of these limitations. They support all counters. The currently known limitations of other processors are as follows:

  • The Intel Core i7, Intel Core 2 Duo, Intel Pentium II, Intel Pentium III, Intel Pentium M, AMD Phenom, AMD Athlon XP and AMD Athlon 64 processors support the Elapsed Time, User Time, User+Kernel Time, CPU Cache Misses, CPU Mispredicted Branches, Context Switches, Hard Memory Page Faults, Soft Memory Page Faults and All Memory Page Faults profiler counters, but do not support the Split Load Replays, Split Store Replays, Blocked Store Forwards Replays and 64K Aliasing Conflicts counters.

  • The Mobile Intel Pentium 4 processor and the AMD Opteron and AMD Turion processors only support the Elapsed Time, Context Switches, Hard Memory Page Faults, Soft memory Page Faults and All Memory Page Faults counters.

  • The Intel Xeon and Intel Xeon MP multi-core processors with the Hyper-Threading technology only support the Elapsed Time, Context Switches, Hard Memory Page Faults, Soft Memory Page Faults and All Memory Page Faults counters.

    The single-core Intel Xeon and Intel Xeon MP processors support all the counters.

Note: If you run AQTime on a 64-bit operating system, then in order to use counters other than Elapsed Time, you may need to run the operating system in debug mode. See Profiling Under 64-bit Platforms for more information.
