Vector Addition using SIMD

#include 

#define VECTOR_SIZE         4
typedef float v4sf __attribute__ ((vector_size(sizeof(float)*VECTOR_SIZE))); // vector of four singl
e floats

typedef union f4vector
{
    v4sf    v;
    float   f[VECTOR_SIZE];
} f4vector;


void print_vector (f4vector *v)
{
    printf("%f,%f,%f,%f\n", v->f[0], v->f[1], v->f[2], v->f[3]);
}

int main()
{
    union f4vector a, b, c;

    a.v = (v4sf){1., 2., 3., 4.};
    b.v = (v4sf){5., 6., 7., 8.};
    c.v = a.v + b.v;

    print_vector(&a);
    print_vector(&b);
    print_vector(&c);
}

Compile with the following command:

gcc -ggdb -mtune=pentium3 -march=pentium3 -c -O3 -ffast-math -mfpmath=sse -msse5 sse.c

To test, just link the object code to binary:

gcc -lm sse.o -o sse

$ ./sse
1.000000,2.000000,3.000000,4.000000
5.000000,6.000000,7.000000,8.000000
6.000000,8.000000,10.000000,12.000000

The assembled code:

$ objdump -dS ./sse.o | grep -2 c.v | tail -8
  7c:   0f 58 c1                addps  %xmm1,%xmm0
  7f:   0f 29 45 c8             movaps %xmm0,-0x38(%ebp)
--
 120:   f2 0f 11 44 24 04       movsd  %xmm0,0x4(%esp)
 126:   e8 00 00 00 00          call   12b <_main+0xdb>
        c.v = a.v + b.v;

        print_vector(&a);

As we can see, it's very optimized where adding 4 components of vector a and b is done in one SSE instruction (addps) instead of multiple instructions if we don't use -msse and -mfpmath=sse



How fast is the program?

$ time ./sse
1.000000,2.000000,3.000000,4.000000
5.000000,6.000000,7.000000,8.000000

Mac OSX Lion: Another Windows remake?

Apple has just updated its website and now it announces that they plan to release another Mac OS-X named "Lion".  A sneak peak to the features, some of the features are not really "wow" me and even seems too-old to be a breakthrough.  For example, "LauchPad".  Windows xx has had it for long time as "Desktop icons".  Another one is "Mission Control" which the similar feature has been in Windows 7 for awhile.

Unfortunately, Apple has not revealed all the features they plan to put in OS-X.  Not sure if the upgrade worth the cost of upgrade (well, if it is only $25 upgrade I'll just go ahead and upgrade mine).

PAM Security explained

PAM Security: http://articles.techrepublic.com.com/5100-10878_11-1055269.html

Login restriction/Limitation based on time schedue

This is how to limit a user (in this case, his name is "Joko") to access computer during weekdays and weekends at certain time duration.

1. Edit file

   /etc/pam.d/common-account

   and add a line "account required pam_time.so"
2. Edit file

   /etc/security/time.conf

   and add the following lines to the end of file.

#services  ttys users   times
#
# allow Joko to use computer during weekdays 3 pm-8:30pm OR weekends 9:00am - 9:00pm
* ; * ; joko; Wk1500-2030 | Wk0900-2100

This will not allow joko to login during weekdays before 3 pm or after 8:30 pm or weekends outside 9 am - 9 pm. To disallow certain service, replace '*' in the first entry with a PAM service name (e.g, login, etc.). Files in /etc/pam.d reflect the service names.

On my computer, the following files are the service names can be used:

Xen Installation & Compilation

Installation from source

Xen 4.0 source code mercurial (hg) repository and changelog: http://xenbits.xen.org/xen-4.0-testing.hg

You can get Xen 4.0 with mercurial using the following command:

hg clone http://xenbits.xen.org/xen-4.0-testing.hg

Note that this will give you the LATEST version in xen-4.0-testing.hg repository! It might be a release candidate for next release or just some developer snapshot. See the changelog above for current status. You can also get a specific 'tag' from the repository like this:

hg clone -r RELEASE-4.0.1 http://xenbits.xen.org/xen-4.0-testing.hg

Alternatively you can download the Xen 4.0.x source tarball from http://www.xen.org/products/xen_source.html . Note that if you're planning to use Xen 4.0.0 tarball please see the Known Issues below for a note about supported pvops dom0 kernel versions.

NOTE!! during the Xen build process outbound git-protocol needs to be open in your network firewall! Xen build scripts need to access git:// repositories on git.kernel.org and xenbits.xen.org. Some people have reported issues accessing the remote repositories - these problems are most often caused by a broken Internet connection, broken firewall, or a broken NAT router you use.

This example will only build the new Xen 4.0 hypervisor and tools. This method does NOT download or build a (dom0) kernel from the xen.git repository. "make tools" part will download the xen qemu-dm ioemu for hvm guests from xenbits git repository and tools tarballs (unless you've already downloaded them yourself before building).

cd xen-4.0-testing.hg 
make xen 
make tools 
make stubdom

When the compilation process finishes you'll have the Xen hypervisor/tools binaries in "dist/" directory ready for installation:

make install-xen 
make install-tools 
make install-stubdom

And then compile your chosen new dom0 kernel, or use your existing dom0 kernel. Also update grub.conf to use the newly installed Xen 4.0 hypervisor.

See XenDom0Kernels wiki page for information about all the available Xen Dom0 capable kernels, and XenParavirtOps wiki page for more detailed information about Xen pvops dom0 kernels.

You can also compile Xen 4.0 together with the new default pvops dom0 kernel (Linux 2.6.32.x in Xen 4.0.1 and newer versions). This method downloads the kernel sources from xen.git repository during the build process:

make world

This will download the latest pvops dom0 kernel 2.6.32.x from Jeremy's xen.git repository during the build process. See the XenParavirtOps wiki page for more information about different pvops dom0 kernel versions. Also see the Known Issues below for supported pvops dom0 kernel versions.

NOTE about the old Xenlinux linux-2.6.18-xen kernels:

make kernels KERNELS="linux-2.6-xen0 linux-2.6-xenU"

The quick solution is to modify <XaraLX directory>/wxOil/ftfonts.cpp.  Edit this file and change from:

#ifdef __WXGTK20__
#include <gtk/gtk.h>
extern GtkWidget *wxGetRootWindow();
#endif

to:

#ifdef __WXGTK20__
//#include <gtk/gtk.h>
extern PangoContext *gtk_widget_get_pango_context    (GtkWidget   *widget);
extern GtkWidget *wxGetRootWindow();
#endif

3D Entertainment

While 3D televisions are more available in the stores, their price is still high and not many people are getting into it.  Perhaps because there is still few BD 3Dd movies.  But now 3D camcoders are going into the market.  We will see if this change how people buy LCD TVs.

Today, when I went to Costco, the 42" 120 Hz LED 3D TV is already below $2000.

Power consumption and Cost saving of Using Ooma (revised)

After awhile, I observed that this Ooma + router consume less power when the temperature is lower.  In the previous blog, I said the average power when its idling is 27 W @ 25 C, but in the early morning when temperature is lower (at about 20 C), the idling power is only 14 W and 17 W when the handset is off-hook.

Power consumption and Cost saving of Using Ooma

Devices measured:

1. Ooma hub
2. Linksys WRT54g wireless router
3. Traditional wired phoneset connected to Ooma

Power-meter: Kill-A-Watt EZ

Result:

• System idle: 27 watt
• Phone is off hook (dial tone): 30 Watt
• Phone is dialing: 30 Watt
• During talk: 30 Watt
• Check voice mail tru the hub: 28 Watt

How much the electricity cost we pay monthly?
For Northern California, PGE has a chart describing the rate.  The average KWH rate for residential seasonal schedule E-8 is $0.22832 (this is just an average, the actual calculation depends on the tier/how much we consume electricity above its baseline).  So, the maximum KWH for Oma in a day is: 30 Watt * 24 hours = 720 WH = 0.72 KWH.  In a month (30 days) = 21.6 KWH or it costs = $4.32

If we don't subscribe to Ooma premier service, there is no additional cost, so it is the actual monthly cost we pay.  If we subscribe to annual Ooma premier service which $119.99/year, we end up paying: $119.99/12 + $4.32 =  $14.32 (rounded up) per month.

As a comparison, when I subscribed to AT&T landline local service (local unlimited), I paid (total, including all the fees and taxes) $27.15.  This did not include caller-ID and all other features.  It was just bare minimum.  With Ooma premier, besides we get caller-ID, we also get two lines, call forwarding (or simultaneous ringing to another number), broadband voice mail (with MP3 file can be sent to email we specified), and other features.  AT&T could have charged those features for additional $15 or more.

Now, how much we save by using Ooma?  OK, first we need to take to the account the broadband portion used for Ooma.  For example, I pay AT&T U-Verse 10 Mbps/1 Mbps (downstream/upstream) $45 a month.  In average, Ooma uses a fractional bandwidth, which is about 256 Kbps.  The max fraction of cost (hypothetically) is then = 0.256/10 * $45/month = $1.152, or about $1.2/month.  Assume we use Ooma premier, the total monthly cost is then $14.32 + 1.2 = $15.52/month.  The saving is = $27.15 - $15.52 =  $11.63/month.


The price of Ooma hub (including one Ooma scout) is $219.99 (at www.ooma.com) +sales tax (which is 9.25% in my area) or $240.34.  The number of months to recover the cost using the amount of money we save above is then $240.34/$11.63 = 20.66 months, or say 21 months (1.75 years).  After that, the saving we collect is going to our pocket.  If you decide not to use Ooma more than 1.75 years, you won't save any.

Note: the calculation above does not include power consumption of Ooma scout, but I surely is smaller than the hub's.
