Hi Guojing;<br>
<br>
Thank you very much for a quick response. I am also copying this
message to the list so that everybody know we have been working on some
mentioned issues.<br>
<br>
1) I confirm, 5 is fixed. Great job!<br>
2) I confirm, 6 is fixed. Very good!<br>
<br>
A related question is how to search for a second occurrence?<br>
<br>
3) We had the histogram capability in previous releases, so why cannot
we continue having it? What has changed since, say, March?<br>
<br>
4) Please take a look at the picture you sent me in the next message:
there are two scroll bars: internal, which is what you are looking at,
and external, which never scrolls.<br>
<br>
Issue 1) Agree - difficult to repeat. But there is second part - broken
PostScript output.<br>
Issue 2) Open<br>
Issue 3) In discussion<br>
Issue 4) Open<br>
Issue 5) Fixed<br>
Issue 6) Fixed<br>
<br>
Basically we have 3 issues, and one discussion.<br>
<br>
Thanks again,<br>
<br>
Vitali<br>

<font face="sans-serif" size="2">I believe I fixed 5, 6, and 3. Note
that the histogram capability would have to depend on another software
that we (IBM) do not own. Besides, the original Xprofiler on AIX
does not have this capability either. If you insist on having that,
we can open another chanel for discussion, and see how we might get
that
for you. There is no technical problem, the issue I believe is purely
legal.</font>
<br>
<br>
<font face="sans-serif" size="2">Now for 1, as it is sporadic,
we will need to find a way to reproduce that in a repeatable manner.
It
might take more time to fix. For 4, there is a partial fix, and we
are working to get it in there. For 2, I am investigating. I
remember the scroll bar is used when there are many function calls. I
will send you a separte note with the xprofiler attached.</font>

<font size="3">Sept 4, 2008: HPCT: Summary of the issues<br>
<br>
1) We want to be able to reduce statistics, generated in mpi_profile.*
files, by some sort of MPI_Start_Statistics()/MPI_Stop_Statistics()
function
calls. As we know from I-hsin, MPI_trace_start()/MPI_trace_stop() calls
control tracing part only.<br>
<br>
2) According to I-hsin, "mpi_profile.<rank number> are generated
per each MPI rank." We do not see this behavior: 4 files are generated
instead with minimal, maximal, mean communication time, and collective
over all tasks statistics file called mpi_profile.0. Please clarify 1)
what is printed at the end of the run, 2) how to print statistics from
a particular MPI task. Examples of the test run would be very useful to
have.<br>
<br>
3) What is IHPCT_BASE env. variable? When I should use it?<br>
<br>
4) peekperf does not show sources for Fortran program.<br>
<br>
5) Fortran instrumented program generates "Error getting the executable
name, line number information will not be available" message.<br>
<br>
6) peekview single_trace gives the node 0, 8, and 15. Example program
was
sent to the list already and contains 2 Sends and 2 Recvs. Where are
the
other communications? See attached screenshot.<br>
<br>
7) peekview on selective instrumentation does not show correct number
of
calls. From 1 Send and 1 Recv, we see nothing on peekview screen.<br>
<br>
8) HPM part does not work: core file at runtime. Please, give us
example
of 1) how to compile HPM-instrumented program, 2) what is the result of
the run.<br>
<br>
9) Xprofiler has 6 open issues:</font>
