    Interview with Tim Dettmers: Which RTX 3000 GPU(s) to get for Deep Learning?

    Posted: 11 Oct 2020 07:47 PM PDT

    Hi Everyone!

    I run a non-monetised, Ad-free interview series as a service to the ML Community where I interview my ML Heroes.

    I had interviewed Tim Dettmers about his GPU advice now that the 3000 series is released:

    Audio, Video

    Edit: For all interviews, I add an intro and some details, this one starts at 2:40 if you'd like to skip the intro. (Thanks to u/PhoBoChai)

    I hope you find this useful and if you've any feedback for me, or guest suggestions, I'd be very grateful. Thanks!

    A review of some cheap 240 GB 2.5" SATA SSDs you'll find on Amazon

    Posted: 11 Oct 2020 12:51 PM PDT

    Why bother?

    I occasionally refurbish and upgrade old PCs and laptops in my spare time. A typical system is 5-10 years old, has a 250GB-1TB HDD, and benefits greatly by installing a cheap SSD. Obviously, I'm not going to buy a high end or NVMe SSD for a system that is worth only a couple hundred dollars. I've yet to find a better source for cheap SSDs than Amazon with Prime delivery. (If you know of one, please let me know, as I'd love to support a smaller business. Newegg has some pretty good free shipping options lately, but their delivery speed and return policy still can't beat Amazon.) But I've noticed a lack of reviews online for cheap or low-end hardware, particularly cheaper SSDs at lower capacities.

    I try to avoid the more obscure, flavor-of-the-month brands if they are only a couple dollars cheaper, but in general, I'm going for whatever is the cheapest at a given "sweet spot" of capacity. Lately the sweet spot for a cheap SSD seems to be 240-256 GB. (It's not much more money to get 480-512 GB, but probably not necessary for most people's boot drives.)

    It's hard to tell which controller and DRAM cache (or lack of cache) is used in these cheaper drives without dismantling them. The specs aren't always revealing. Manufacturers have even been known to swap to a different controller without changing the model number. Apparently the Kingston A400 and the Patriot Burst use the Phison S11, which has some bad reliability reports online.

    Here are some benchmarks on a few popular 240 GB SSDs, as well as a WD Blue 1TB for comparison.

    Test setup

    • Dell Optiplex 790, i5-2400, 8GB DDR3, Q65 chipset
      • Doing these benchmarks taught me that some older motherboards, like the one in my business-surplus Dell, only have 6 Gbps in a few select SATA ports. And sometimes a motherboard will downgrade a 6 Gbps port to 3 Gbps if another drive is plugged into a port on the same "channel". So you have to be careful!
    • Windows 10 Pro + AS SSD + ATTO Disk Benchmark
    • Closed all running applications before each test and closed background apps where possible
    • Cloned my boot drive (about 80GB of OS, apps, and games) to each SSD to test under "real world" conditions
    • I also made a half-hearted attempt at testing garbage collection
      • Filled each drive to 100% with random data and then re-ran the benchmarks
      • Then wiped each drive and re-ran the benchmarks again
      • I didn't save the raw numbers but just made a note of how the drive "felt" and how long it seemed to take to recover back to normal performance.

    Kingston 240GB A400 SATA 3 - SA400S37/240G

    • $27.99 USD (I'm in Canada but will quote all prices in USD.)
    • Cheap, popular and reliable, at least according to Amazon's 4.7/5.0 review rating.
    • Benchmarks:
      • AS SSD: 326 total score
      • ATTO: Very slow random write performance, reaching a max of ~230MB/s only at the 32KB block size.
    • Garbage collection: Mediocre

    Patriot Memory Burst 240GB SATA III - PBU240GS25SSDR

    • $31.99 USD
    • Affordable and reliable (4.7/5.0 Amazon review rating)
    • Well known brand
    • Benchmarks:
      • AS SSD: 1319 total score
      • ATTO: Fast and consistent
    • Fast and stable
    • Garbage collection: Very good. Maintained high speed even after random fill. Perhaps this is because of having more "spare area" compared to the SP A58, which offers a full 256GB of space.

    Silicon Power 256GB SSD 3D NAND TLC A58 Performance Boost SATA III

    • $31.25 USD (based on current exchange rate; seems to only be available in Canada right now)
    • Affordable and reliable (4.6/5.0 Amazon review rating)
    • Relatively well known brand
    • Benchmarks:
      • AS SSD: 1644 total score (Fastest 4K threaded random burst speed of the bunch, but this might be a caching artifact with AS SSD.)
      • ATTO: Fast
    • Slightly higher capacity (256GB vs 240GB).
    • Garbage collection: Good. Performance declined temporarily once the drive was full of random data, but recovered a few minutes after wiping.

    Western Digital 1TB WD Blue 3D NAND SATA III - WDS100T2B0A

    • $104.99 USD
    • Very reliable (4.8/5.0 Amazon review rating)
    • Very well known brand. (Despite the recent Red NAS ZFS performance fiasco with their HDDs, they are still a venerable brand and one of the few pure storage companies left. I also really like their blog. They have a lot of interesting stuff to say about SSD testing, benchmarking, endurance, etc. They obviously put a lot of thought into their products.)
    • Benchmarks:
    • Garbage collection: Didn't test that on this drive.

    Conclusion

    From the three 240 GB class drives I tested, I'd pick the Silicon Power A58. It was slightly larger and faster than the Patriot Burst, at the expense of a little shakier garbage collection. Since few people I know run their system drives at > 90% capacity, I'd say the garbage collection is not a crucial issue.

    I would avoid the Kingston A400. It just seems overrated for what it brings to the table, and is riding on its strong consumer brand recognition.

    Amazon often offers ~$5 discount promos on these drives, so if you can get the Patriot Burst for significantly cheaper than the Silicon Power A58, that's probably a better deal. I'll also continue to look at alternatives and try to update this post with test results if I get the opportunity. (I'm interested in benchmarks for the Crucial BX500, PNY CS900, and ADATA SU635, SU655, and SU800, if you know of any sources for those.)

    Can FPGAs be used to cache instructions run by a CPU?

    Posted: 11 Oct 2020 02:19 AM PDT

    Sorry if this seems like a dumb question. I'm not familiar with FPGAs and recent rumors of AMD acquiring Xilinx has made me wonder if it is possible for an FPGA to automatically cache and accelerate frequently run instructions of a CPU like how a memory cache would store frequently accessed bits of memory used by the CPU?
