The h1iopomc0 model changes I prepped this morning LHO:78956 have been installed.

Further, one at at time, I've installed copies of the primary OMC DCPD A0 and B0 filter bank filters into the A1, A2, and B1, B2 filters in order to test the consumption of computational turn around time (see preliminary discussions in LHO:78958). Finally, I've added a reasonably high-order high-pass filter into the A1 and B1 banks to test whether we can add even *more* filters enough to accomplish the tests discussed in LHO:78956.

Attached is an annotated time series of the CPU meter channel (H1:FEC-179_CPU_METER) as each of these things happened.

In short -- even with new the filters "fully loaded," the model computational turn around time runs at 12 [usec], occasionally popping up to 13 [usec] -- under the ideal limit of 15.3 [usec].
In addition, we don't see any IPC timing errors in either the OMC user model or the end station PI models that are receiving IPC from the h1iopomc0 model.

So, we'll leave this diagnostic infrastructure in place for a few weeks, until we decide we don't need it anymore.
