Future developments:

1. The inclusion of HFT is necessary, but not urgent, since 
the completion of HFT is aimed for run-14 with Pixel available. 
The HFT hit information will be passed to GL3 machines,
while the TPC information will be passed to SL3 machines,
and the committee is curious about how and where the re-fit 
of the track is carried out.

2. The efficiency study via Monte Carlo seems to focus on
the relative efficiency between HLT and offline data,
instead of the full/absolute efficiency. 
The advantage is that the offline performance is well 
understood, and much less effort is needed than 
the full efficiency study.
The caveat is that the relative efficiency has to be safely
factorized out of the full efficiency.

3. What's the time line for rewriting the SL3 tracking package?

4. How necessary is it to add the HLT information into MuDst?
Once the MuDst is produced, all the information that HLT provides
can be obtained with the analysis code.
And the MuDst production is usually separated into several
physics streams, so some streams can be defined with HLT triggers,
and then the HLT information doesn't need to be written into MuDst.

Manpower:
Hao will graduate next year, and Xiangming could be away.
They both work on tracking, which means the HLT project 
could be badly short of manpower in tracking.
On the other hand, the development of secondary vertex
finder with GPU may be not so urgent.
