On Regret of Parametric Mismatch in Minimum Mean Square Error Estimation

HPL-2010-10 On Regret of Parametric Mismatch in Minimum Mean Square Error Estimation - Fozunbal, Majid
Keyword(s): Dereverberation, Error, Estimation, Fisher Information, Mismatch, MMSE
Abstract: This paper studies the effect of parametric mismatch in minimum mean square error (MMSE) estimation. In particular, we consider the problem of estimating the input signal from the output of an additive white Gaussian channel whose gain is fixed, but unknown. The input distribution is known, and the ...

pci_eh_enable

pci_eh_enable(5)						File Formats Manual						  pci_eh_enable(5)

NAME

       pci_eh_enable - enables/disables PCI Error Recovery

VALUES

   Failsafe
   Default
	(Enables PCI Error Recovery.)

   Allowed values
       Integer values from to

   Recommended values
	(Enables PCI Error Recovery.)

DESCRIPTION

       HP-UX supports PCI Error Handling/Recovery to ensure that PCI errors caused by bad cards do not crash a hard partition on high end systems.
       This functionality helps in recovering the most common parity errors.  This tunable is made static because it is very hard to modify  hard-
       ware capability at run time.

       is made public so certain service guard users would be able to turn off the functionality.

   Who Is Expected to Change This Tunable?
       Recommended for service guard customers.

   Restrictions on Changing
       Changes to this tunable take effect at next reboot.

   When Should the Tunable Be Turned On?
       This tunable should be turned on to enable PCI Error Recovery functionality

   When Should the Tunable Be Turned Off?
       To disable PCI Error Recovery functionality

   What Are the Side Effects of Turning the Tunable Off?
       PCI Error Recovery functionality will be disabled

WARNINGS

       Even if tunable is PCI Error Handling/Recovery functionality will be disabled if the platform does not have the capability.

       All  HP-UX kernel tunable parameters are release specific.  This parameter may be removed or have its meaning changed in future releases of
       HP-UX.

       Installation of optional kernel software, from HP or other vendors, may cause changes to tunable  parameter  values.   After  installation,
       some  tunable  parameters may no longer be at the default or recommended values.  For information about the effects of installation on tun-
       able values, consult the documentation for the kernel software being installed.	For information about optional kernel  software  that  was
       factory installed on your system, see at
