Compiling Scavenger From Source to add OpenCL Support

Hyena Speedracer helmet

Now that I have Scavenger up and running on the ODROID-XU4, it’s time to do a little optimization to see how much I can really get out of it. For this I’m going to use 1.6.0 from the releases page. Download¬†Source code(tar.gz). The development team has some really great information on all of the configuration options on the github wiki, so make sure to check that out if you’re going to try this on your… Read more »

Scavenger 1.6.0 vs. creepMiner 1.7.18 – 32 Bit Showdown

Hyena Staring at You

On October 8th, Scavenger 1.6 was announced, which is pretty exciting for us miners using Linux on a 32-bit ODROID-XU4! Not only does the 1.6 update add support for 32-bit machines using ARM7, but it also has NEON support! Scavenger 1.6 can be downloaded on the PoC-Consortium GitHub page here. Previously, I had started a little work on a few projects that might have sped up my mining rig, including porting Blago’s miner, adding NEON… Read more »

Burstcoin Mining on an ODROID-XU4 and creepMiner OpenCL

ODROID-XU4 Gone to Plaid

This post is a follow-up to a question posted by Anton on my earlier article about setting up the ODROID-XU4 as a Burstcoin mining rig. Anton asked if the ODROID-XU4 could handle running creepMiner with OpenCL, and as it turns out, yes it can! If you look at the ODROID specs on the Hardkernel site, you’ll see that it supports OpenCL 1.2 Full profile. This means I should be able to run creepMiner in that… Read more »

PoC1 to PoC2 Burst Plot Conversion Results

Conversion

These results are from over a month ago at this point, but I thought it would be worth posting for anyone who is still converting (hopefully nobody) and those who read this blog (definitely nobody.) The Seagate conversion went MUCH better than expected and I absolutely recommend converting the SMR drives vs. re-plotting. The final result using Johnny’s converter was a little under 34 hours, which compared with the 190 hours to initially plot is… Read more »

Burstcoin PoC1 to PoC2 Conversion Speed Tests

Converting Hard Drive

Before converting my entire mining capacity, I wanted to do a few tests to see what might make the most sense. Would it be better to convert one drive at a time? Would it make more sense to convert all at once? Is converting faster than re-plotting? To get some results without taking hours or ruining perfectly good plot files, I started creating some 5GB plots with TurboPlotter 9000. From my previous 500GB conversion, I… Read more »

Adding a PoC2 Plot File to the Burst Mining Mix

PoC2 Format Plot Files

The old 500GB Western Digital My Book (USB 2) finished converting from the PoC1 format to PoC2 in 7 hours, 24 minutes. I don’t know why exactly it took so long, but now it’s time to add it to the ODROID-XU4 Burstcoin miner that I have set up. The first step will be to download and compile the new creepMiner that’s compatible with PoC2 plot files. I’ll be using the 1.7.18 version, which can be… Read more »

Valid Deadlines Last 360 Blocks

Valid Blocks

I’ve been mining with three 8TB drives for about a week now and the highest I’ve seen Effective Capacity is around 19TB. Since the actual capacity of the 3 drives is around 21.82TB, I’d like to at least see that number over 20. While writing this, it’s actually down to a little over 16TB with 308 Valid Deadlines in the last 360 blocks. I know that my ODROID-XU4 setup will read all 3 drives in… Read more »

Effective Capacity Test #3

Here we are 5 days after starting the Effective Capacity testing, and here are some results. I’ve seen that the laptop gives better results, and that looks like it’s due to a jump in around 10 valid deadlines. Now, there’s always a bit of chance involved, but it looks to me like the valid deadlines are higher possibly due to a few blocks ending before the ODROID could finish reading the plot… or it could… Read more »

Creating a Dedicated Low Energy Burstcoin Mining Rig with ODROID-XU4

ODROID-UX4

While there are many great benefits to mining Burstcoin, it does share the drawback of other cryptocurrencies like Bitcoin in that you need to leave your machine on, whether it’s your ASIC, GPU rig (which may be obsolete) or just the old PC you had lying around that you decided to mine BURST with. In my case, my 9-5 job is at home doing web development, so my work laptop is on during those hours… Read more »

Optimizing Effective Capacity Test #2

After 24 hours, it looks like my Effective Capacity has actually gone down slightly. The previous screenshot from 24 hours ago had an Effective Capacity of 13.7834 TB. Currently, after my slight Target Deadline tweak, it shows 13.3888 TB. I peeked at it about 11 hours into the test and it was showing close to 15 TB, so I had high hopes.. but it looks like I’m actually down 3.9% from yesterday. So, the next… Read more »
