My computer
We like to mess around with hardware and stuff. We think it would be interesting if other people posted about their hardware/software setup. There is always some new stuff we can learn!
We use our computer for the usual boring things and also for playing Factorio and running msieve. Our primary criteria when choosing parts is reliability. If a part is flaky it is immediately replaced. Once we find something reliable we rarely deviate from that part. We will (eventually) post followups to this thread with our thoughts regarding certain parts in the list below. And maybe some pictures since those are fun! Code:

My daily driver is a cheap Celeron laptop running Kali Linux. It is based on eMMC but has a SSD fitted for "home". I chose it because it does not use much juice but I am able to get things done with it, unlike somewhat under-performing ARM devices.
I also have an eclectic mix of crunching hardware, mostly self built or mutilated. For example an i3 9100f running in a case which originally belonged to a Athlon 1000MHz setup. I have a 550w total Mersenne crunching box with an 850w Corsair PSU consisting of a Xeon Phi and a Radeon Vii. Pride and joy is the 64 core 3990x which is water cooled and has a basic SSD -- nothing special except the chip. I have other stuff in various stages of functionality, for example: An AMD 1090T connected to a projector, a Raspberry Pi 3B+ which is destined to run retro gaming, a Longan Nano RISC-V microcontroller with display, a not-used-enough Xilinx Spartan 6 FPGA development board -- I need to get some decent literature on how to program it properly -- and various USB disks, caddy and pens connected to a couple of hubs, a 1000Mbs switch, a cheap EdgeIO 1080p monitor. Apart from running Kali on my laptop I opt for Debian all the way. My dream machine is a dual Epyc 7h12 with 256GB RAM. Last fiddled with by paulunderwood on 2023-04-05 at 20:45 |

Besides my work-issued laptop, my daily driver laptop is a Dell XPS 13 Developer Edition from 2013. It's getting very long in the tooth, but still functions. Intel i7-3537U (4 threads, 2 cores, 3.1 GHz turbo) with 8 GB of DDR3 1600. As I replaced the battery about 4 years ago, that still works well. I also replaced the SSD when it died with a 1 TB Samsung 860 EVO that made the system significantly snappier.
I've also got a desktop that's an i9-6800k with 128 GB of DDR4 2400. I recently upgraded the memory for doing large P-1. It has a 1070. Then there is my five node cluster of i5-6600 with 32 GB of DDR4 2133. I've been doing a lot of P-1 with this the past 4 months. Three still have 1070 GPUs, two lost to hardware failure. Lastly is my old mining rig. It's got a Pentium G4400. It's got a single 8 GB stick of DDR4. I run mprime on a single core to keep it from freezing. I need to adjust the C-states in the BIOS. Oh, and it had 8 x 3070s. I have an i5-7400 to swap in once I shut that system down for the summer. I should probably buy more RAM. Plus I got about ten more systems I could build out of parts. I need new power supplies, but good ones have gotten expensive. |

As shipped to me, an HP Z820 arrived with dual Xeon e5-2690 CPUs, a 960GB SSD, & 128GB ram (8 16GIB DIMMS, PC3-10900R) installed all to the left of the CPU sockets, resulting in dual-channel mode operation and 8 empty DIMM sockets on the right. Prime95 performance in P-1 seems to have gone up over 60% after spending a few minutes today to move half the DIMMs from white sockets on the left to black sockets on the right. Quad channel after and dual channel before moving the DIMMs were confirmed with CPU-Z. The system also contained a Quadro K620 GPU, which is painfully slow for any GIMPS applications, but adequate for running a console.
This is my second Z820/2x E5-2690. The first has 64GB ram (8x 8GB PC3-12800R), in quad channel mode as received, and has had a variety of GPUs in it, beginning with a Tesla C2075 and Quadro K4000 as received. |

We also post about our setup because it is an easy way for us to document what we have done, in case we have to do it again.
Here is a picture of the guts of our computer. Unfortunately Noctua doesn't make 180mm fans.

For the storage in this system we used 5 Optane drives in a RAID 0 array. The filesystem is BTRFS. (We have the file metadata set up as RAID1.) Optane SSDs are interesting because they are the fastest random-seek reading drives you can get. They also have a ridiculous endurance rating. https://www.storagereview.com/review...-memory-review https://www.pcgamer.com/intel-optane...-need-to-know/ They aren't super fast for sequential reading and writing, but when they are striped together they get a lot faster. Code:
$ sudo btrfs scrub status / UUID: 97b3d1f3-bba2-4eab-95ca-ce76db3c7eda Scrub started: Fri Apr 7 18:30:22 2023 Status: finished Duration: 0:00:14 Total to scrub: 108.03GiB Rate: 7.72GiB/s Error summary: no errors found The splitter card works through a mechanism called bifurcation. The B550 chipset on our motherboard is a bit limited in PCIe lanes so we had to get a bit creative. We used the (traditional) video card slot for the bifurcation board and a slower/narrower slot for the video card. M.2 #1 uses CPU lanes - PCie4 ×4 @ PCIe3 ×4 = SSD #1 PCIe slot #1 uses CPU lanes - PCie4 ×16 @ PCie3 ×16 = SSDs #2 through #5 PCIe slot #3 uses PCH lanes - PCie3 ×4 @ PCie3 ×4 = GPU And after all that we are out of PCIe lanes, so we can't use any more PCIe slots or M.2 slots. Fortunately (?) the video card is "cut down" to only 4 PCIe lanes from the factory so putting it into a 4× slot doesn't kill the performance too badly. We only play Factorio so this GPU is more than adequate even though we play at 4K resolution. Here is some more filesystem info: Code:

My daily driver dedicated to msieve (not anymore at the moment) or NFS@Home since 2012 is an old Toshiba laptop with an i7-3630QM CPU, 16GB of memory. Think it has been running NFS@Home 24/7 for the last 4 years in a row.
