Share Your Anecdotes: Multicore Pessimisation

I took a look at the specs of new 7000 series Threadripper CPUs, and I really don't have any excuse to buy one, even if I had the money to spare. I thought long and hard about different workloads, but nothing came to mind.

Back in university, we had courses about map/reduce clusters, and I experimented with parallel interpreters for Prolog, and distributed computing systems. What I learned is that the potential performance gains from better data structures and algorithms trump the performance gains from fancy hardware, and that there is more to be gained from using the GPU or from re-writing the performance-critical sections in C and making sure your data structures take up less memory than from multi-threaded code. Of course, all this is especially important when you are working in pure Python, because of the GIL.

The performance penalty of parallelisation hits even harder when you try to distribute your computation between different computers over the network, and the overhead of serialisation, communication, and scheduling work can easily exceed the gains of parallel computation, especially for small to medium workloads. If you benchmark your Hadoop cluster on a toy problem, you may well find that it's faster to solve your toy problem on one desktop PC than a whole cluster, because it's a toy problem, and the gains only kick in when your data set is too big to fit on a single computer.

The new Threadripper got me thinking: Has this happened to somebody with just a multicore CPU? Is there software that performs better with 2 cores than with just one, and better with 4 cores than with 2, but substantially worse with 64? It could happen! Deadlocks, livelocks, weird inter-process communication issues where you have one process per core and every one of the 64 processes communicates with the other 63 via pipes? There could be software that has a badly optimised main thread, or a badly optimised work unit scheduler, and the limiting factor is single-thread performance of that scheduler that needs to distribute and integrate work units for 64 threads, to the point where the worker threads are mostly idling and only one core is at 100%.

I am not trying to blame any programmer if this happens. Most likely such software was developed back when quad-core CPUs were a new thing, or even back when there were multi-CPU-socket mainboards, and the developer never imagined that one day there would be Threadrippers on the consumer market. Programs from back then, built for Windows XP, could still run on Windows 10 or 11.

In spite of all this, I suspect that this kind of problem is quite rare in practice. It requires software that spawns one thread or one process per core, but which is deoptimised for more cores, maybe written under the assumption that users have for two to six CPU cores, a user who can afford a Threadripper, and needs a Threadripper, and a workload where the problem is noticeable. You wouldn't get a Threadripper in the first place if it made your workflows slower, so that hypothetical user probably has one main workload that really benefits from the many cores, and another that doesn't.

So, has this happened to you? Dou you have a Threadripper at work? Do you work in bioinformatics or visual effects? Do you encode a lot of video? Do you know a guy who does? Do you own a Threadripper or an Ampere just for the hell of it? Or have you tried to build a Hadoop/Beowulf/OpenMP cluster, only to have your code run slower?

I would love to hear from you.

Garbage Truck Driver Saves Discarded 32-Core Threadripper PC with RTX 2080 Ti

Threadripper PC with RTX 2080 Ti found in the trash? Garbage collectors often come across valuable or intact items, but discovering a largely functional, premium PC might be one of the luckiest finds in recent memory. Despite the components being a few years old, the system booted up perfectly after some clever repairs and minor upgrades. Reddit user and garbage truck operator "Siezio" recently shared (and then deleted) photos of a gaming PC he reclaimed from the dumpster and successfully restored. The setup featured an AMD Ryzen Threadripper 3970X, a GeForce RTX 2080 Ti with 11GB of VRAM, and 32GB of DDR4 RAM. The only missing part was internal storage, and as a precaution, Siezio replaced the water-damaged power supply unit (PSU). After thoroughly cleaning the other components with isopropyl alcohol and allowing them to dry for two days, the system powered on without any issues.

While Siezio had found other PCs in the trash before, they were either irreparably damaged or decades old. In contrast, the 3970X and 2080 Ti are fairly recent, being just five and six years old, respectively. Both were top-tier components at launch and still perform admirably today. The Threadripper 3970X is a powerhouse with 32 cores that was launched in 2019 with a hefty price tag of $1,999. We gave the workstation processor high praise in our review at its release. On the other hand, the GPU, which originally retailed for $999, was a leading contender when it hit the market in 2018. It was last tested in our benchmarks for Warhammer 40,000: Space Marine 2 last September, where it performed on par with contemporary mid-range graphics cards like the RTX 3060 Ti. Acquiring a used 3970X and 2080 Ti together in 2024 would likely set you back around $1,000.

Not surprisingly, many users reacted to Siezio's discovery with envy, questioning why someone would discard a computer that likely cost over $3,000 without making an attempt to sell it. The hardware was released shortly before external factors like the cryptocurrency boom, import tariffs, and supply chain issues inflated electronics prices. While this PC is the most valuable find in Siezio's three-and-a-half years of work, it isn't the only useful item he's salvaged. He has also discovered a power drill worth €250, multiple ratchet sets, an unopened Bluetooth keyboard that now operates his TV and a chainsaw that needed only a new spark plug. Moreover, almost all of Siezio's tool collection for his car was rescued from the trash. While many of the items were initially broken, tutorials on YouTube made the repairs straightforward.

The company reported for the third quarter of fiscal year 2023 A few days after Intel, AMD also published its financial report. The company has completed the third quarter of fiscal year 2023. [caption id="attachment_78911" align="aligncenter" width="780"] AMD's[/caption] If Intel's revenue decreased and net profit fell by more than 70%, then AMD's situation is better. Revenue rose 8% to $5.8 billion, and operating profit amounted to $224 million versus a loss of $64 million a year earlier. Net income rose more than 1,000% to $299 million. AMD's net profit grew by 1000% and equaled Intel's net profit By the way, Intel's net profit was only $1 million higher, which is very interesting. At the same time, Intel's revenue is almost 2.5 times higher than that of its competitor. It’s also worth noting that the data center products segment did not grow year-on-year in the past quarter, although it has been actively driving AMD’s revenue upward in recent years. But sales in the consumer segment increased by 42%, mainly due to the full entry into the market of Ryzen 7000 mobile APUs. AMD's gaming business fell 8% due to lower revenue from sales of semi-custom products.

i can't take AMD "Threadripper" CPUs seriously because Threadripper the Hedgehog sounds like the name of a Sonic OC whose whole deal is that he's like a more edgy version of Shadow.

AMD’s Next-Gen TRX50 Motherboards

AMD Threadripper 7000 central processor units will be supported by the next-generation TRX50 motherboards that are currently being developed by AMD’s board partners. These motherboards are now in the process of entering mass production.

Threadripper 7000 HEDT & Workstation CPU AMD TRX50 Motherboards Have Been Found

This time around, ASRock is working on the TRX50 WS, a motherboard that will employ AMD’s TRX50 socket and WS chipset and will provide compatibility for the most current Threadripper 7000 “Storm Peak” processors.

ASRock always has its full stack prepared, regardless of whether they are working with mainstream or workstation systems. This motherboard has been listed by the EEC (Eurasian Economic Commission), and it is projected that it will be accessible in the fourth quarter of 2023, when the lineup is expected to be on shop shelves.

As suggested by its name, this particular motherboard appears like it will be focusing on the workstation side of things as its primary market. ASRock’s current TRX40 product portfolio included the Taichi and Creator products. These weren’t only geared at providing workstation-class functionality, rather, they were also influenced by gaming aesthetics.

It has been four years after the debut of the TRX40 series. However, at the same time, ASRock was also releasing the WRX80 series as part of the Creator family. This series was built specifically for “WX” PRO chips. This motherboard had support for eight channels of RAM and included a generous number of PCI Express lanes.

It’s possible that the same thing will happen here with the AMD TRX50 motherboards, which will keep the lineup basic and make it more user-friendly for high-end desktop computers, while the WRX series range will concentrate on providing customers with an abundance of functionality to meet the needs of the workstation market. That there will be two platforms for the Threadripper 7000 CPUs is something that we are aware of, and something that we have also very recently verified with a variety of motherboard manufacturers.

One will support 4-channel memory, while the other will support 8-channel memory. While the HEDT platform is expected to have the LGA 4844 “SP6” socket with 4-channel memory and 64 PCIe Gen 5 lanes support, the WS platform is expected to have the LGA 6096 “SP5” socket with support for up to 8 channels of memory and 128 PCIe Gen 5 lanes. Similarly, the majority of motherboard manufacturers specialized on HEDT “TRX” components rather than the Workstation SKUs. With the next-gen lineup, it may be the case as well.

Late in the year 2023 is when it is projected that the next-generation AMD Ryzen Threadripper 7000 “Storm Peak” central processing units would be introduced for the first time, provided that all goes according to plan. You should prepare to get further information sometime during the next several months.

Already next week The Starfield game, as you know, was created with the active support of AMD and works much better on Radeon video cards. However, owners of GeForce adapters will soon have a reason to rejoice, as DLSS will be added to the game. [caption id="attachment_78515" align="aligncenter" width="780"] AMD's[/caption] AMD's Starfield Game Will Get DLSS 3 Before FSR 3 Next week the developers will release a beta version of the update, which will bring many changes. True, it’s not very clear why the beta version, but we just have to wait for the release. Among other things, the update will bring support for DLSS, and judging by the mention of frame generation, it will be DLSS 3. Bethesda also promised to add FSR 3 to the game, that is, frame generation technology will become available for Radeon adapters. Considering that Starfield turned out to be very demanding, such improvements will clearly not be superfluous.

✨Hello im here to jump scare you with my shitpost doodle✨

This is a drawing based off smth i wrote down in the draft for my fan continuety for my fanfic, yeah i know this is a crack ship gone wrong but i rather embrace my ideas than live in fear of never knowing if they were good or not plus anyways i love drama.

This is a really sort version of the lore because i started typing it whilst in uni so i didn’t have enough time to fully type out the lore that i came up with during a rp i did with a friend about it.

Shockwave divorced Imperious delirious and took the kids after imperious delirious failed to look after them tbh the screenshot explains better what happened.

The tf ocs in the drawing are my ocs the threadrippers or what’s left of them Quipfire, Grailchaser, Gingersnap and Rainwhisper.

This might look like a shitpost but some part of it is true which is the part where shockwave locks away imperious delirious.

I might do more mini lore doodles like this in the future to atlest have proof that im working on my fanfic.

I don’t have anymore to say cause the screenshots speak for themselves.

Doing server maintenance tonight. At the end of the night I should have 7 different computers all hooked up together. Only problem is I have no idea what I want to do with all this computing power. I essentially have a cheap AMD Threadripper at my disposal.

Maybe I'll keep banging my head against Fortran to try and get my neural network to actually function. I'm running into problems with how to store the neural network data. Fortran doesn't have dynamically sized arrays so I have to either put in a big high rank array or have a bunch of smaller arrays with less manageable code.
