To CCK El Khawarizmi

 


Good day

I am Wadï Mami, a computer engineer (ENSI class of 2000).

I'm sharing my idea for sequencing all data ( example DNA and so whatever) in the shortest possible time.

The idea is to use the Java Spring Batch framework to sequence a portion of the database table Data , 

then run multiple instances of this program in parallel to sequence the entire Database table ( see picture above).

This concept can be used in parallel computing across various fields, such as mathematics and

 physics pushing parallel computing to the limits.

To break through the limitation of 20 parallel executions in Spring Batch 2.0, you must modify your 

XML or Java configuration to override the framework's internal multi-threading defaults and resource 

pools.


Now Spring Batch 6 eliminates previous parallel processing limitations by introducing a completely

 rewritten chunk-oriented concurrency model based on a bounded producer-consumer pattern.


Here I will speak about one node think if we have a grid of Pcs or servers. I will use a matrix of SB

 (spring Batch) allowed by RAM memory and disk space the same thing goes for jdk (RAM

 availability and disk storage) I create the following


[PathToJDK1]/jdk1

[PathToJDK2]/jdk2

[PathToJDK3]/jdk3

[PathToJDK4]/jdk4

[PathToJDK5]/jdk5

.

.

.

.

.

.

[PathToJDKn]/jdkn


On every [PathToJDKi]/jdk"i"/bin folder copy spring Batch executable program file generated by mvn

 -package command lets call it SB1 for the first one and then copy it into multiple SB program so we

 have for every jdki/bin the following

[PathToJDKi]/jdk"i"/bin/SB1

[PathToJDKi]/jdk"i"/bin/SB2

[PathToJDKi]/jdk"i"/bin/SB3

[PathToJDKi]/jdk"i"/bin/SB4

[PathToJDKi]/jdk"i"/bin/SB5 .

.

.

.

[PathToJDKi]/jdk"i"/bin/SBn


here n is the number limit allowed by a single jvm jdk"i" memory limit to execute your multiple SB

 java program instance.

Then launch all in parallel with different parameters for all Spring Batch instances on all JDK/bin

 folders like the following in a batch file commmand


 [PathToJDKi]/jdki/bin/java SBl -version"il" like


so we have

 [PathToJDK1]/jdk1/bin/java SB1 -"11"

 [PathToJDK1]/jdk1/bin/java SB2 -"12"

[PathToJDK1]/jdk1/bin/java SB3 -"13"

.

.

.

[PathToJDK1]/jdk1/bin/java SBn -"1n"

[PathToJDK2]/jdk2/bin/java SB1 -"21"

[PathToJDK2]/jdk2/bin/java SB1 -"22"

 [PathToJDK2]/jdk2/bin/java SB3 -"23"

 [PathToJDK2]/jdk2/bin/java SB4 -"24"

....

 [PathToJDK2]/jdk2/bin/java SBn -"2n"

...

..

.

.

.

 [PathToJDKi]/jdki/bin/java SBl -"il"

.

..

. [PathToJDKi]/jdki/bin/java SBn -"in"

..


etc

Goldbach’s conjecture proven

In the name of God, the most gracious, the most merciful Thanks be to God, Lord of all worlds Peace and blessings be upon the noblest of messengers. Goldbach’s conjecture proven By me Wadï Mami Email : wmami@steg.com.tn / didipostman77@gmail.com Date : 30/10/2025   Goldbach's conjecture  is one of the oldest and best-known  unsolved problems  in  number theory  and all of  mathematics . It states that every  even   natural number  greater than 2 is the sum of two  prime numbers . ---------------------------------------------------------------------------------------------- A prime number must be an odd number except 2 The sum of 2 odd numbers is an even number Then The sum of two prime numbers is an even number except 2 (A).

Résolution de la conjecture de Goldbach

  Résolution de la conjecture de Goldbach Auteur : Wadï Mami Date : October 30, 2025 Email : wmami@steg.com.tn / didipostman77@gmail.com Enoncé de la conjecture de Goldbach "Tout nombre pair supérieur à 2 est la somme de deux nombres premiers." Un nombre premier est un nombre impair, sauf 2. La somme de deux nombres impairs est un nombre pair. Alors La somme de deux nombres premiers est un nombre pair, sauf   pour 2. (A) Reste maintenant à démontrer l’autre sens pour la conjecture. En se basant sur le théorème d’Erdös qu’il a établi quand il avait 18 ans : Pour tout entier n > 1, il existe toujours un nombre premier entre n et 2n. Donc il existe Un nombre premier p entre n et 2n n <= p <= 2n      (I) et par analogie il existe un nombre premier q entre n/2 et n n/2<= q<= n       (II) (I)             +  ...
