Chaba Di A Fela Guide

The phrase “Chaba di a fela” did not disappear, but its meaning shifted. It became a reminder of the urgency of life. The village learned that while they could not stop the silent thief entirely, they could ensure that when the "nations" grew back, they would find a harvest waiting for them.

Mme Masechaba stood up, her joints creaking like the old gates of the village. She didn't offer a prayer of mourning; instead, she walked to the center of the circle. Chaba Di A Fela

Mme Masechaba sat on her woven mat, her eyes fixed on the dusty path leading to the graveyard. She had buried her third son that morning. As the village elders gathered under the great Lekgotla tree, the air was heavy with the phrase that had become a bitter greeting: “Chaba di a fela” —the nations are perishing. The phrase “Chaba di a fela” did not

The phrase (or “Ditshaba di a fela” ) translates from Sesotho or Setswana as "Nations/Tribes are perishing" or "People are dying." In Southern African literature and oral tradition, this is a somber and powerful theme often used to describe periods of great suffering, such as the impact of the HIV/AIDS pandemic, war, or social decay. Mme Masechaba stood up, her joints creaking like

That afternoon, despite the grief, the remaining elders of Manyeneng did something they hadn't done in years. They took the children to the communal fields. They taught small hands how to turn the soil and bury the seeds. They sang the old songs, not as dirges, but as rhythms for work.

CPU Stress / Torture Testing

Prime95 has been a popular choice for stress / torture testing a CPU since its introduction, especially with overclockers and system builders. Since the software makes heavy use of the processor's integer and floating point instructions, it feeds the processor a consistent and verifiable workload to test the stability of the CPU and the L1/L2/L3 processor cache. Additionally, it uses all of the cores of a multi-CPU / multi-core system to ensure a high-load stress test environment.

From the most recent "stress.txt" file included in the download:

The Prime95 Wikipedia page has an excellent overview on using Prime95 to test your system and ensure it is working properly. The tips presented there should be helpful regarding how long to run the torture test and provide a solid guideline on how long to run the Prime95 stress test.

Performing a stress test is simple:

1. Download the software and unzip the files to your desired location.
2. Run the Prime95 executable and select "Just Stress Testing" when asked.
3. The default options are sufficient to do a well balanced stress test on the system.

Upgrade Instructions for Existing Users

1. Download the appropriate program for your OS

2. Upgrade the software. Stop and exit your current version, then install the new version overwriting the previous version. You can upgrade even if you are in the middle of testing an exponent.

3. Restart the program.

4. Read WhatsNew.txt

Questions and Problems

Please consult the readme.txt file for possible answers. You can also search for an answer, or ask for help in the GIMPS forums. Otherwise, you will need to address your question to one of the two people who wrote the program. Networking and server problems should be sent to . Such problems include errors contacting the server, problems with assignments or userids, and errors on the server's statistics page. All other problems and questions should be sent to , but please consult the forums first.

Software Source Code

If you use GIMPS source code to find Mersenne primes, you must agree to adhere to the GIMPS free software license agreement. Other than that restriction, you may use this code as you see fit.

The source code for the program is highly optimized Intel assembly language. There are many more-readable FFT algorithms available on the web and in textbooks. The program is also completely non-portable. If you are curious anyway, you can download all the source code (37.7MB). This file includes all the version 30.19b21 source code for Windows, Linux, FreeBSD, and Mac OS X. Last updated: 2024-09-14.

The GIMPS program is very loosely based on C code written by Richard Crandall. Luke Welsh has started a web page that points to Richard Crandall's program and other available source code that you can use to help search for Mersenne primes.

Other available freeware

At this time, Ernst Mayer's Mlucas program is the best choice for non-Intel architectures. Luke Welsh has a web page that points to available source code of mostly historical interest you can use to help search for Mersenne primes.
