Jumped over to the Lenovo workstation world RIP Dell

[newwurldmn]

what are you crunching that needs this supercomputer?

i think its worth it. A computer like that will last 8-10 years between computing horsepower and quality of components. So he's amortizing $500-700/year. I did something similar in 2018 and that computer would still be used for my trading. I just reupped because i needed a second computer for work flow.

Building out the new 2024 trading workstations and Lenovo has some really nice systems way better prices (40% lower) than the closest Dell Precision model. And the P7 is a significantly better chassis it even has an IPL diagnostics screen on the front like the IBM AS/400s etc.. Tool less etc..

Its quite big and weighs 50 pounds. A deskside supercomputer.


I will be expanding it to 128gb to fill all 8 memory channels (307gb/s memory bandwidth) adding 2 Radeon Pro VII cards as well (13 teraflops double precision capacity 1024GB/s memory bandwidth with ECC)

adding an SN840 6.4tb SSD as well and a Lenovo PCI card for 4x Optane P1600x drives which will take the heavy random I/Os

P7 model
Processor Intel® Xeon® W7-3445 Processor (2.60 GHz up to 4.80 GHz)
Operating System Windows 11 Pro for Workstations 64
Graphic Card NVIDIA RTX™ A2000 12GB GDDR6
Memory 32 GB DDR5-4800MHz (RDIMM, ECC) - (2 x 16 GB)
Storage 2 TB SSD M.2 2280 PCIe Gen4 Performance TLC Opal
AC Adapter / Power Supply 1400W
Pointing Device USB Optical Mouse
Keyboard USB, Traditional, Black - English (US)
WLAN Intel® Wi-Fi 6E AX210 2x2 AX vPro® & Bluetooth® 5.1 or above
Warranty 3 Years On-site

What is the benefit of Xeon over i9 processor?

Just curious what needs so much computing power. Most modern applications don't utilise all cores. Also a very well built and cooled overclocked system can go a long way

But a warranty and a standard system reduces risk. That’s my opinion.

Running optimizations. I have a Lenovo ThinkStation P7 with dual Xeon. Some optimizations take 4-5 hours.

TLC SSD won't work for long time.

Absolutely agree. I built my Win-10 Pro system back in April/2016 using all high quality components at a cost just shy of $3k. Originally built it to edit videos using Adobe's suite of products. I don't edit videos anymore, just use it for trading. Next month will be eight years and it's still going strong. I did have to replace the display panel last summer but, other than that, no issues. Money well spent.

Thats just going to be used for Boot. Thats why my Storage for the workloads are SN840 6.4tb SSDs They have PLP so you can disable fsync() for max write IOPS and will do 3 drive writes per day.

For ultralow latency the Optanes get leveraged, those work on phase change so you can directly write on top of data just like magnetic DASD. They can be slammed with random writes all day long.

What is the benefit of Xeon over i9 processor?

ECC
AVX-512
High memory bandwidth due to 8 channels you get 307 Gbyte/sec which is critical for HPC
And a few other things.

even top shelf i9 could only do about 89 Gbyte/sec. Xeon gets you a bit over 3x the performance to feed the beast.

In the early 90s a Cray C916 could do 245 Gbyte/sec memory bandwidth and those systems cost millions and required lots kilowatts to run. Amazing that you can build a machine today that destroys that in performance and consumes a few hundred watts.
