Having gotten boinc running on my desktop, I installed
on my Linux laptop (P4 with HT, kernel 2.6.6 compiled
with SMP, Fedora core 2 with updates).

The hadsm3um_4.10 processes (it sees the system
as a 2 CPU system) core dump with signal 11
after running for only 90 CPU seconds or so.
They show up as defunct processes in ps.

The gdb output from the core doesn't say much:

Program terminated with signal 11, Segmentation fault.
0x0857e64c in trans_source_coeff_.H()
Cannot access memory at address 0xbfff9a94

This happens consistently every time I stop and
restart the client (four times now). Well, the
crash is as the same spot although sometimes the
bad address is 0xbfff9584 instead of 0xbfff9a94.

Any suggestions?

Thanks in advance,
Ben

P.S. This same machine has run SETI Classic for 2 weeks at
a time 24x7 so I don't think it's a hardware problem.

I too am having problems with hadsm3um_4.10_i686-pc-linux-gnu
running on Mandrake 10.1. Its a dual CPU machine and one
thread downloaded a new packet a couple days ago, still
running 4.04, and its running fine. The new thread
just downloaded a packet today and got 4.10. It will
stop after timestamp 85.

Does anyone from the project actually read these forums?

Yep, at least sometimes. My earlier post about 'new participant finds no
work available' was answered by "Tolu" as a Project Admin.

Climateprediction works fine on my single processor desktop. When I see a
new version of hadsm3um get downloaded onto it, I'll try climateprediction
again on the SMP laptop. Till then the laptop is 100% setiathome (which I
recently converted from classic to BOINC with no problem, except the power
outages SETI has been experiencing this week).

4.11 has been released for Linux. I think you have to do a project reset on climateprediction.net to get the new version, which would likely drop your 4.04 model as well. Does 4.11 fix the problem you are seeing? I don't know.

Thank you. That seemed to do the trick.
