Charm++ parallel programming system

[Phil Miller <mille121 AT illinois.edu>]

Hi Vijay,

Could you provide a bit more detail, as follows:

- What command did you use to compile Charm++?

- What command did you use to run your test program?

- What is the full output from the runtime's startup preceding the backtrace shown? It should look something like
====
Charmrun> started all node programs in 1.674 seconds.
Converse/Charm++ Commit ID: v6.6.0-rc2-23-g590e140
Charm++> scheduler running in netpoll mode.
CharmLB> Load balancer assumes all CPUs are same.
Charm++> Running on 1 unique compute nodes (8-way SMP).
Charm++> cpu topology info is gathered in 0.005 seconds.
====

Please keep replies on the list, so that others can both offer help and benefit from the outcome.

Phil

Hi,

I get the following error when I try to run a charm++ program which initializes a chare array by the statement "personArray = CProxy_Person::ckNew(numPersons);" (line# 21 in main.C). I have attached my .C, .ci files.

pgm:29995 terminated with signal 11 at PC=4c0ba3 SP=7fffffffcaa0.  Backtrace:

I am not able to figure out why segmentation fault arises. Can you help me in finding out what I am doing wrong?

- Vijay.
