Has anyone here gotten the new Matlab 7.01 for x86_64 to work? I loaded it up on a 9.2Pro machine and a SLES9 machine and it segfaults on both. I noticed on the mathworks site that it was built using a 2.4 kernel. Could that be the cause?
Thanks, Joe
It works fine for me...
Im using SuSE 9.1pro and uname -a gives Linux v 2.6.5-7.145-smp #1 SMP Thu Jan 27 09:19:29 UTC 2005 x86_64 x86_64 x86_64 GNU/Linux
And the command ver in matlab gives ver ------------------------------------------------------------------------- ------------ MATLAB Version 7.0.1.24704 (R14) Service Pack 1 MATLAB License Number: xxxxx Operating System: Linux 2.6.5-7.145-smp #1 SMP Thu Jan 27 09:19:29 UTC 2005 x86_64 Java VM Version: Java 1.4.2 with Blackdown Java-Linux Team Java HotSpot(TM) 64-Bit Server VM ------------------------------------------------------------------------- ------------
The machines by the way are dual opterons 1.8GHz (4GB) and 2.4GHz (12GB)
SP1 works fine for me as well on SuSE 9.1. Since I've only just started migrating to 9.2 I hadn't noticed, but it segfaults there. Even with -novjm and -nosplash. Fujitsu Siemens desktop with AMD 64 3200+, SuSE 9.2 Pro and 2.6.8-24.11-default.
I've been comparing strace outputs on SuSE 9.1 on Opteron, SuSE 9.2 on Athlon 32 (both work fine) and SuSE 9.2 on AMD64 (which segfaults). The latter strace output is _littered_ with gettimeofday() and time() calls which aren't in the other two outputs.
Googling reported something similar on RHEL 3, where it was a kernel bug. Neither acpi=off nor various perturbations of clock= (tried tsc, pmtmr, and pit) had any effect.
Matlab R14 SP2 is out, I'll have to give that a try to see if it solves the problem - I'm just glad I found out before I went into production with 9.2 on my desktop machines. Thanks Joe.
