Highload ++: How to help the ERP system deal with 50?000 requests per second

We at X5 process a lot of data in the ERP system. There is an opinion that no one processes more than us in SAP ERP and SAP BW in Russia. But there is one more thing - the number of operations and the load on this system is increasing rapidly. 3 years we "fought" for the performance of our ERP-heavyweight, filled a lot of cones, and what methods they were treated, we tell under the cut.

A tenth-grader from Siberia wants to become a processor designer. Why shouldn't she make a FPGA neuro accelerator?

A tenth-grader from Siberia wants to become a processor designer. Why shouldn't she make a FPGA neuro accelerator?Yesterday I received a letter from a tenth-grader from Siberia, who wants to become a microprocessor developer. She has already received some results in this area - she added a multiplication instruction to the simplest schoolMIPS processor, synthesized it for the Intel FPGA MAX10 FPGA, determined the maximum frequency and increased performance of simple programs. She first did all this in the village of Burmistrovo, Novosibirsk Region, and then at a conference in Tomsk.
 
 
Now Dasha Krivoruchko (that is the name of the tenth grader) has moved to live in a Moscow boarding school and asks me what ...

The friendship thanks to which Google has grown to enormous size

The friendship thanks to which Google has grown to enormous size 3r3184. By programming together with one computer, Jeff Dean and Sanjay Gemawat changed the company's course - and the entire Internet. In the illustration: the best Google programmers sometimes seem to be the two hemispheres of one brain. Figure by David Plckert [/i] 3r33434.

One day in March 200? six top Google engineers gathered in a makeshift conference room. There was a state of emergency: since October 199? the crawlers stopped. Although users are still given search results, but they are out of date for five months. More was at stake than engineers had imagined. At the moment, Larry Page and ...

Storage Class Memory in the storage system - if you need even faster

 3r3174. 3r3-31. Storage Class Memory in the storage system - if you need even faster As you probably remember, HPE has long invested in the topic of new types of data warehousing (of course, The Machine ) And in optimizing access to the repositories (our membership in Gen-Z consortium ). 3r3143.  3r3174. 3r3143.  3r3174. The goal of this movement is to speed up the work of our customers' applications. And the movement is multilevel: while the completely new architecture of the computer systems The Machine (the so-called memory-centric architecture) is being forged, we understand that we need to accelerate now. Let's see it can be done today, and what will HPE have ...

Cool the CPU in the data center - laser 3D printing will help

The University of Binghamton (New York) have developed a new technology for cooling processors, which will allow to abandon the thermal paste. Thermally conductive material is applied directly to the surface of the chip using 3D printing. According to experts, their solution can lower the operating temperature of processors in data centers by 10 ° C. 3r? 3175.

Former vice president of Sun and DEC became president of MIPS /Wave, talks about Russia and RISC /V

 3r395. 3r3-31. 15 minutes ago, Art Swift became President of MIPS, before that he was Vice-Chairman of the Marketing Committee of RISC-V, Vice-President of Sun, DEC, Cirrus Logic, President of Transmet. I was the first to take a video interview with him in his new role, and his first words were about Russia. Art said he was familiar with Baikal Electronics, ELVIS-NeoTech. NIISI, MCST and Babayan group, met with Russian RISC-V companies Syncore and CloudBear. Here's a video - it ended at the end, as I ran out of battery: 3r382.  3r395.

I, as a developer, joined the project in 2015-201? I don’t remember exactly, but he worked 2-3 years earlier. The project was very popular in its field, namely game servers. How strange it did not sound, but projects on game servers are being carried out to this day, I recently saw vacancies and worked a bit in one team. Since the game servers are built on the already created game, therefore...
