 Posted: Thu Sep 22, 2005 6:38 pm Post subject: PGI compilers on Dual Dual-Core Opteron Segfault! |
 |
|
I am struggling with getting PGI (Portland Group Fortran Compilers - pgf90 and pgf77) running on a dual dual-core Opteron box (2x 270's) with a Tyan Mobo (K8SD-Pro --> S2882-D).
I keep getting Signal 6 and Signal 11's (Segfaults). I have tested the crap out of this RAM (I compiled the Gentoo AMD64 install from Stage 1) and have run Memtest86 for like 40hrs straight with no problems reported (I'm running 8 1-Gig Corsair XMS ECC Registerd DDR400 RAM modules)
Anyway, I had the PGI running on this system and compiled a simple fortran program. Then I installed libstdc++-v3 to satisfy another app and now PGI is broke - giving me the signal 6 (pgf90) and signal 11 (pgf77) errors.
Any thoughts would be appreciated.
This is my system:

Just in case anyone is interested. The PGI fortran compilers segfault without fail after running pamstamp 2g (the commercial app that needs PGI)
It's crazy, but PGI will work fine on a fresh system, but after I execute the pamstamp solver, they segfault. Reboots do not help. ldconfig does not help. 
I've tried this on Red Hat Enterprise 3 AS, RedHat Enterprise 4 AS, and Gentoo. Some results on all.
So the problem is in the pamstamp product, not PGI. They are currently looking into the problem, but so far, no luck.
