hello everyone ,
Im new to HPL. i wanted to know whether High performance linpack solves linear
system of equations for single precision airthmatic on LINUX.
it works for double precision , so is there any HPL version which is for single precision.\
thanks . (0 Replies)

mcxquery(1) BSD General Commands Manual mcxquery(1)NAME
mcxquery -- Managed Client (MCX) compositor query tool
SYNOPSIS
mcxquery [options] [-user recordName] [-group recordName] [-computer spec]
options:
-o path Writes output to a file at the specified path.
-format space | tab | xml Specifies the format of the output.
-computerOnly Ignore values for -user and -group.
-useCache Return the cached computer settings in the local node if they are available.
-raw Dumps Directory Service data for records contributing to managed preferences.
-forApple Convenience for specifying options when sending bug reports to Apple. Currently enables "-raw" and "-for-
mat xml". See usage example below.
DESCRIPTION
mcxquery is a utility to determine the effective managed preferences for a user logging in to a workgroup from a specific computer.
-user Specify the short name of the user record to read managed preferences from. If this parameter is omitted, or a value of "=" speci-
fied, the short name of the currently logged in console user will be used.
-group Specify the short name of the group record to read managed preferences from. A value of "=" may be specified to mean the name of
the workgroup (if any) chosen for the current login session.
-computer Specify the computer record to read managed preferences from. The computer can be specified using either an Ethernet MAC address
(e.g. "11:22:33:44:55:66"), a Hardware UUID (e.g. "00112233-4455-6677-8899-AABBCCDDEEFF") or the short name of the computer record
itself (e.g. "lab1_12"). If this parameter is omitted, or a value of "=" specified, the record for the current computer will be
used.
EXAMPLES
mcxquery -user jane -group science -computer lab1_12
Displays the managed preferences that would be in effect if user "jane" logged in using workgroup "science" from the computer speci-
fied in the "lab1_12" computer record.
mcxquery -user jane -group science -computer 11:22:33:44:55:66
Displays the managed preferences that would be in effect if user "jane" logged in using workgroup "science" from a computer with an
Ethernet MAC address of 11:22:33:44:55:66.
mcxquery -user = -group = -computer guest
Displays the managed preferences that would be in effect if the current user logged in using the current workgroup into a computer
not specified by any computer record (i.e. a "guest" computer).
mcxquery -user jane -group math
Displays the managed preferences that would be in effect if the user "jane" logged into the "math" workgroup on the current com-
puter.
mcxquery -o /tmp/report.txt -format xml -user jane
Writes the managed preferences that would be in effect if user "jane" logged into the current computer without a workgroup. The
report is written in XML format to /tmp/report.txt.
mcxquery -computerOnly -computer lab1_12
Displays the managed preferences for the computer specified in the "lab1_12" computer record only. Useful for determining managed
settings when computer is at login window.
mcxquery -computerOnly -computer 00112233-4455-6677-8899-AABBCCDDEEFF
Displays the managed preferences for the computer with the Hardware UUID "00112233-4455-6677-8899-AABBCCDDEEFF". Supported on Mac OS
X 10.6 and later.
mcxquery -forApple -o results.plist
Creates a plist, suitable for submitting along with bug reports to Apple, containing the managed preferences for the current user on
the current computer. Also includes relevant records from Directory Services. Supported on Mac OS X 10.7 and later.
