[LLVMdev] Performance problems with FORTRAN allocatable arrays
I've noticed that LLVM does a bad job of optimizing array indexing
code for FORTRAN arrays declared using the ALLOCATABLE keyword.
For example if you have something like the following:
DOUBLE PRECISION,ALLOCATABLE,DIMENSION(:,:,:,:) :: QAV
...
ALLOCATE( QAV( -2:IMAX+2,-2:JMAX+2,-2:KMAX+2,ND) )
...
DO L = 1, 5
DO K = K1, K2
DO J = J1, J2
DO I = I1, I2
II = I + IADD
IBD = II - IBDD
ICD = II + IBDD
QAV(I,J,K,L) = R6I * (2.0D0 * Q(IBD,J,K,L,N) +

Boot Failure Lastest CEntos 7 Kernel on X9SBAA-F Board
...kernel kernel-3.10.0.229.1.2.el7.x86_64 appears not to like
our Supermicro X9SBAA-F board. It fails on boot with the last message
before panic being apic_timer_interupt . Previous kernels load very well.
We erased and reinstalled the kernel, it verifies good as does everything
else using "rpm- qaV".
Anyone have any ideas?? Pretty hard to troubleshoot when you just get the
last few lines on the screen.

Corrupted RPM DB can't be rebuilt.
Alle,
I have a major problem. I'm running CentOS 5.5 on some rather old
hardware (Dual Celeron 500MHz with 768MB of memory). Sometime in the
last week, the DB became corrupted (I noticed when yum update would hang).
I've tried running rpm --rebuild with both the 2.6.18-194.17.4 and
2.6.18-194.26.1 kernels and get a segmentation fault each time.
Consequently, I'm pretty much stuck

Yum update corrupted something badly - can only get access through SSH terminal or Webmin
Hey there -
This morning I ran the yum updater through Webmin as I do every month
or so - after about two hours I realized that I still had the same
updating screen going - and no response. Seemed strange.
Simple attempts to kill it didn't work so I sent a command to reboot
the system - that seemed to work, till I turned on the monitor
directly connected to the server -
I saw this
