Adaptive Buffer Tuning for Data Intensive Algebraic Operations in Purpose of Parallel and Distributed Processing

Both pervasive directional graphs and intensive algebraic operations require buffer management for stochastic data processes with constrained computing resources. Algebraic computation states in final stages tend to be readily identified within finite time horizon by sensing very abrupt transitions in system and network state spaces. But in early stages of constraints, these changes are hard to predict and difficult to distinguish from usual state fluctuations. Dynamic buffer allocation and replacement are the major techniques to construct structures for algebraic operations to ensure finite resource assesses. Hence, dynamic buffering function and control optimization are the major primitives to construct utilities for stochastic system processes to ensure converged resource accesses. To provide adaptation to large dimensional states, this research proposes a formal model-free buffer utility framework rooted from reinforcement learning methods and dynamic programming techniques to provide self organization of buffers to exploit parallel based buffer tuning processes. To time and space complexity reduction within the large state spaces, dynamic hidden neurons with incremental tuning is proposed for non-linear value function approximation to derive optimization procedures for optimal algebraic computational policies. For numeric and information evaluation, convergence analysis and error estimation are presented. Finally, a simulation test-bed and tuning results are deliberated.

CVS Server Setup on Solaris 10

(1) download cvs binary
(2) init cvs repository
a. create repository root directory /usr/local/cvs-repository
b. create a Solaris system user/group as: cvs/cvs
c. grant ownership of /usr/local/cvs-repository to Solaris user/group cvs/cvs
d. cvs -d /usr/local/cvs-repository init
This will create repository CVSROOT under /usr/local/cvs-repository
(3) create cvs user/password
a. create a password file as "passwd" under CVSROOT directory
b. user pl file below to create encoded password for cvs user
c. assign password to solaris user "cvs"

The CVS password file is CVSROOT/passwd in the repository. It was not
created by default when you ran cvs init, because CVS doesn't know for
sure that you'll be using pserver. Even if the password file had been
created, CVS would have no way of knowing what usernames and passwords
to create. So, you'll have to create one yourself; here's a sample
CVSRoot/passwd file:

::
Here is the perl script to generate encoded password
#!/usr/bin/perl

srand (time());
my $randletter = "(int (rand (26)) + (int (rand (1) + .5) % 2 ? 65 : 97))";
my $salt = sprintf ("%c%c", eval $randletter, eval $randletter);
my $plaintext = shift;
my $crypttext = crypt ($plaintext, $salt);

print "${crypttext}\n";


I keep the preceding script in /usr/local/bin/pass.pl:

pass.pl "passwd"

output : Urmh23wFp1aOs

Then use the output passwd adding line in CVSROOT/passwd file

cvs:Urmh23wFp1aOs:cvs

(Here we create cvs user and solaris user same as "cvs")


The format is as simple as it looks. Each line is:

::

c. in the /etc/inetd.conf add one line as

cvspserver stream tcp nowait root /opt/sfw/bin/cvs cvs --allow-root=/usr/local/cvs-repository pserver


d. On Solaris 10 inetd.conf change does not take effect other than SFM service profile.
using "inetconv" command to convert the inetd.conf as /var/svc/manifest/network/rpc/100235_1-rpc_ticotsord.xml
In addition, add online in /etc/services to give permission
cvspserver 2401/tcp
e. this service file will be auto started by SFM daemon
f. verify pserver service is started
# svcs | grep cvs
online 14:18:27 svc:/network/cvspserver/tcp:default
g. use login test

cvs -d :pserver:cvs@:/usr/local/cvs-repository login

Setup Acer Solaris x86 WIFI

Acer Aspire 9300, Solaris X86, Atheros Wifi NIC
Submitted by spp on Tue, 2006-10-31 12:22.

Got the Atheros 802.11abg NIC working on my new Acer laptop under Solaris X86. I tried to follow the instructions at the atheros driver page, but they are a little out of date. The atheros driver has been integrated into OpenSolaris, so only one or two instructions are correct. However, it did put me on the right track.

First we need to make sure the driver is attached and we can start the interface

1. Find the vendor and device IDs
#/usr/X11/bin/scanpci
pci bus 0x0004 cardnum 0x05 function 0x00: vendor 0x168c device 0x001a
Atheros Communications, Inc. AR5005G 902.11abg NIC
2. Check in /etc/driver_aliases for Atheros (ath) mappings. Format of file is 'alias "pciXXXX,YYYY"' where XXXX is "vendor 0xXXXX" and YYYY is "device 0xYYYY" minus any beginning zeros.
#grep ath /etc/driver_aliases
ath "pci168c,13"
ath "pci168c,1014"
3. update the driver to include the new device (note that the single quotes are needed in order to pass through the double quotes
#update_drv -a -i '"pci168c,1a"' ath
4. now, plumb the interface
#ifconfig ath0 plumb
5. either now, or before the plumb, you can find out what wifi access points are available
#wificonfig scan
essid bssid type encryption signallevel
you should see a list here

At this point, the instructions say that if you aren't running authentication, you can just use "ifconfig ath0 dhcp", but I am using encryption, so I moved on to trying to use wificonfig. Unfortunately, there are some mistakes here (possibly out of date and changed, not strictly incorrect). The biggest issue I found was that the instructions always reference using "-i [interface]", but that option isn't valid for most of the configuration (and the error message doesn't really make it easy to see).

1. create a profile to store my ESSID and WEP information in (write-only profile, non-readable). Names changed for security... not that wepkey# has to be the actual WEP key, not the passphrase, which makes life significantly more difficult.
#wificonfig createprofile home essid=HOME encryption=WEP wepkey1=10hexkey
2. activate the profile
#wificonfig connect home
wificonfig: connecting to profile 'home'
3. Now, like the earlier instructions, you can start dhcp
#ifconfig ath0 dhcp
4. And, make sure we have connection
#ifconfig ath0
ath0: flags=201004843 mtu 1500 index 3
inet 192.168.21.100 netmask ffffff00 broadcast 192.168.21.255
ether 0:16:cf:6f:a:92

LDAPv3 Unauthenticated binding

LDAPv3 specifications have introduced a unituitive feature with regards to authentication : the unauthenticated bind.
When an LDAP application provides a DN but no password, the Bind request is succesfull, BUT the user is not authenticated and has the same access rights as an Anonymous user.

Note that DS 6.0 now has a configuration parameter to disable unauthenticated Binds, and remove this unconventional authentication "feature" of LDAPv3.

LDOM Virtual Disk

LDom vdisks are not SCSI disks . Therefore, the missing SCSI target ID
and disks have the name cNdNsN.

Bind raw or block disk to disk service

bind a raw disk (/dev/rdsk/c1t1d0)
bind to a block disk (/dev/dsk/c1t1d0) to a disk service.

Zones and ZFS Pool

Two zones created on a cluster in node 1 in a ZFS pool, since I need to have the zones in an installed state on each node in the cluster. There is a way to bypass having to install the zones on each node in the cluster? It is using shared storage and moving the zfs pools back and forth.

Just three simple steps

1. zonecfg -z zone1 export>myfile
2. failover the storage with the root path to the second node
3. get myfily over to the second node
4 configure the zone with zonecfg export -f myfile
5 attach the zone with -F

FIPS compliance Security Crypto Module

Federal Information Processing Standards (FIPS) are publicly announced standards developed by the United States Federal government for use by all non-military government agencies and by government contractors. Many FIPS standards are modified versions of standards used in the wider community (ANSI, IEEE, ISO, etc.)


The National Institute of Standards and Technology (NIST) issued the 140 Publication Series to coordinate the requirements and standards for cryptographic modules which include both hardware and software components for use by departments and agencies of the United States federal government. FIPS 140 does not purport to provide sufficient conditions to guarantee that a module conforming to its requirements is secure, still less that a system built using such modules is secure. The requirements cover not only the cryptographic modules themselves but also their documentation and (at the highest security level) some aspects of the comments contained in the source code.

http://en.wikipedia.org/wiki/FIPS_140
http://en.wikipedia.org/wiki/Federal_Information_Processing_Standard

Sun's Cryptographic Accelerator 6000 provides exactly such a storage mechanism and API/tool set. The Cryptographic Accelerator is available for Solaris (SPARC and x86/x64) and Linux and is FIPS 140-2 Level 3 certified. It's key storage mechanism is also RF shielded and tamper-proof. It's probably one of the fastest cards on the market for accelerating SSL, IPsec/IKE and other general crypto and it's inexpensive (less than $1500 list).

ld: fatal: symbol is multiply-defined:

ld: fatal: symbol `bar' is multiply-defined:
(file foo.o and file bar.o);
ld: fatal: File processing errors. No output written to int.o

foo.c and bar.c have conflicting definitions for the symbol bar. Because the link-editor cannot determine which should dominate, the link-edit usually terminates with an error message. You can use the link-editor's -z muldefs option to suppress this error condition, and allow the first symbol definition to be taken.

fatal: relocation error: R_AMD64_PC32

I am developing a c simulation tool. I am invoking one of dynamic library
(my home grown library named as: randlib.so)

It has a function as

double unifrand(double, double, long*);

In my simulation application, I invoke the above function with

seed = 1236537;
ran_no = unifrnd(0.0,1.0,&seed);

I have flag below to build

cc -m64 -o dist/Debug/Sun12-Solaris-x86/simperturbation build/Debug/Sun12-Solaris-x86/estimator.o build/Debug/Sun12-Solaris-x86/spoptimze.o -R/SunStudioProjects/randlib/dist/Debug/Sun12-Solaris-x86 -R/usr/sfw/lib/64 -lm /SunStudioProjects/randlib/dist/Debug/Sun12-Solaris-x86/randlib.so


However, during runtime, I have error blow:

ld.so.1: simperturbation: fatal: relocation error: R_AMD64_PC32: file /SunStudioProjects/randlib/dist/Debug/Sun12-Solaris-x86/randlib.so: symbol unifrnd: value 0x2800112fedf does not fit


If I run list dynamic dependencies with the target simulation application binary,

NIO or IO

It seems block or non-blocking address the FD limitation previously existing on the server. There is a work around to improve the FD limitation. However, from server socket processing with sequential by nature. I tend to suggest to take blocking IO for normal mid-large workload but small-mid workload take unblocking approach since it functionally replicate Queuing algorithms

Inetmenu good for Laptop

It is a good tool to assign IP for laptop

It requires root to run then get IP from DHCP server or Wireless Access Points.

S11 NV build Laptop

(1). Solaris Express, Developer version build installation
(2). If it is under SWAN, it will bypass a lot of setup to go straight with default
NIS process.
(3). It requires sys-unconfig process if you want change other things. Do not enable DHCP here
but use inetmenu

However, sys-unconfig will not give you option to change host name

So, it is important to get hostname change process.

To change the hostname on a Solaris system:

1. Change the hostname in /etc/nodename
2. Run uname -S new_hostname to change the nodename for your current session.
3. Change the hostname in /etc/hostname.network_interface (e.g. /etc/hostname.hme0)
4. Run hostname new_hostname to change the hostname for your current session.
5. Change the hostname in /etc/hosts
6. Change the hostname in /etc/net/*/hosts (/etc/net/ticlts/hosts, /etc/net/ticots/hosts, /etc/net/ticotsord/hosts)
for directory in ticlts ticots ticotsord
do
cd /etc/net/$directory
sed 's/old_hostname/new_hostname/g' hosts > hosts.new
mv hosts.new hosts
done
Solaris 7 or later additional instructions:
7. Change the hostname in DUMPADM_SAVDIR= line in /etc/dumpadm.conf

Solaris 10 additional instructions:
8. Change the hostname in /etc/inet/ipnodes
