Hello, Sophia;<br>
<br>
3) Yes, I understood that from Christoph's message.<br>
<br>
4) the source is in current directory. The message comes: "Cannot
generate the binary analysis file!". Opening the sources from
File->Open Sources does not locate the calls from the viz files, and
therefore impractical.<br>
<br>
5) I do not use MP profiler.<br>
<br>
with best regards,<br>

3) What is IHPCT_BASE env. variable? When I should use it?<br>
</font><br>
<font size="4">Answer: It is recommended to set up the IHPCT_BASE
environment variable. It may be required for some of the components in
the toolkit. It is safe to always set this variable first. Please refer
to the env_csh file in the hpct installed directory. For example, if
you install HPCT at /usr/local/ihpct_2.1, the IHPCT_BASE env. variable
should be set to this installed path.</font><br>

4) peekperf does not show sources for Fortran program.<br>
</font><br>
<font size="4">Answer: peekperf will try to open the sources. If
peekperf cannot find the files in the current working directory, it
should pop up a dialog to ask where the top-level source code directory
is. If peekperf still fails to locate, you can always use File->Open
Sources to open the files.</font><br>
<font size="4"><br>
5) Fortran instrumented program generates "Error getting the executable
name, line number information will not be available" message.</font><br>
<br>
Answer: Did you use the mp profiler? The MP profiler should be able to
get the executable name. If not, there may be some problem here.<br>

<font size="4">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>

hi Vitali,<font size="4"> <br>

</font><br>
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 size="4"> <br>
</font><br>
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 size="4"> <br>

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><br>
1. <font size="4">Load Files, Filter -> Uncluster functions, File
-> Screen Dump -> Select Target Window, </font><br>
1. <font size="4">clicking now on the main window may occasionally
cause crach </font><br>
2. <font size="4">resulting file Xprofiler_screenDump.ps.0 is a
balack-box Postscript </font><br>
2. <font size="4">The meaning on exterior scroll bars in not clear,
they never scroll. </font><br>
3. <b><font size="4">Removing Histogram functionality is unacceptable</font></b><font
size="4"> A more complicated multistep example </font><br>
1. <font size="4">Load Files </font><br>
2. <font size="4">Report -> Flat Profile </font><br>
3. <font size="4">Code Display -> Show Source Code </font><br>
4. <font size="4">File -> Save as; File -> Close </font><br>
5. <font size="4">Code Display -> Show Histogram w/Source Code </font><br>
6. <font size="4">crash </font><br>
4. <font size="4">Load Files, Report -> Flat Profile, Code Display
-> Show Source Code, File -> Save as </font><br>
1. <font size="4">Close the window by clicking X (not File ->
Close) </font><br>
2. <font size="4">Select another function in Flat Profile </font><br>
3. <font size="4">Code Display -> Show Source Code; File -> Save
as; crush </font><br>
5. <font size="4">Load Files, Report -> Flat profile, Show Source
Code, search anything non-existent, press enter, crash </font><br>
6. <font size="4">Load Files, Report -> Flat Profile, try to search
anything like 'asfsafd', once not found press Enter, crash <br>
