BitMinter client v1.3.0beta2 is ready for testing.

News since beta1:

Improved automatic timer tuning and hash rate detection for Icarus FPGAs.
Improved FPGA error handling, should fix lockup that could happen with beta1.
Fix bug introduced in beta1, crash when unplugging FPGA while mining.
Bugfix: detect CPU model on Raspberry Pi, and hopefully other ARM systems.
Only scan USB ttys on Linux - prevents many error messages about ttySxx.
Bugfix on Linux: devices detected by a full probe and devices added
through probing a specified port were named differently and it was possible
to add the same device twice.
Sort devices alphabetically when dynamically adding external devices
to device display.
Default to compact display for anything but the bottom "total" display.
Do not start CPU when clicking "total" display's start button for the first
time after starting the program, unless it is the only device. Would
previously start all visible (non-hidden) devices.
Added X-Mining-Hashrate HTTP header to report hash rate to server.
Staggered start of devices when multiple devices are started with the button
on the status line or the "total" display's start button. Should give
a smoother start up of (multiple) BFL minirigs.
When going to performance mode remember the old window size and restore it
when going back to detailed mode.

Yeah, I went to that link, but it said if you want the mac drivers to contact them... should I do that?

Just click the version number in the table for 32-bit, 64-bit or PowerPC depending on your CPU. I don't think you need "VID/PID combination" (whatever that is), so no need to contact them.

Is it possible to mine on a Butterfly Labs single FPGA unit from a Mac? I've been unable to do this... it says "No COM ports found" when I try to scan for FPGA devices. Device works on Windows, have yet to test on Linux.

Yep, when you scan for devices and it doesn't find any it will give you some hints in the log.

Try grabbing Mac drivers from http://www.ftdichip.com/Drivers/VCP.htm

Edit: The stable version runs fine on Mac. But if it's not too much bother I'd love to hear how the beta runs (look a few posts back). Hopefully it still runs fine and with low CPU usage.

The beta version runs great from what I can see, aside from the FPGA issue it seems great and fast, low CPU...

Beautiful screenshot, Fefox. I have to wipe a tear from my eye. Grin

Will BitMinter have BFL SC support before they are released?

I have contacted BFL about that, and it's what I'm aiming for, yes.

Very nice Fefox. Both Icarus and BFL are mining here without problems. Doc is the man.

BitMinter client v1.3.0beta1 is out! A big thank you to Turbor for access to his system with Icarus and BFL single for testing.

Here are the news:

Support Icarus FPGA devices
Fix "class not found" bug on Raspberry Pi
Implemented getwork extension: midstate
(calculate midstate on client instead of server, reducing server load)
Implemented getwork extension: rollntime (with "expire" support)
(get more than 1 work unit in a single request to the server)
Dynamic work queue size
Expire proof of work if undeliverable for 15 minutes
Expire (non-rollntime) work unit if unprocessed for 5 minutes
Bugfix: don't count as device miscalculation when a proof of work exceeds
difficulty 1 but not the (above 1) difficulty given by the server

TL;DR: Support Icarus, Raspberry Pi and very high hash rates.

I made a lot of changes to the serial port handling (BFL and Icarus). I'm interested in hearing about any old features that may be broken, specifically whether mining on Mac with FPGAs still works without high CPU usage, and new stuff: mining on Icarus, mining with Raspberry Pi (with Icarus or BFL), and mining on Cairnsmore with Icarus bitstream. Or anything else you find good or bad. Wink

I have an Icarus you could use. Do you have TeamViewer?

Thanks that would be great. Yep, I have TeamViewer. Use PM or [email protected] for details.

For the next miner version I'd like to add support for Icarus and Cairnsmore FPGA devices. If you can give me remote access to a computer with one for testing, please let me know.

Thanks for your reply.

I can't see that these temps are too high, but I'll give it a try by using another firmware.

Thanks

When I start the speed rises up to its supposed maximum. Temperature is between 45° and 55° C. After a short while it seems to start throttling and these messages show up.

Yeah, if it is throttling it's not responding to commands for some seconds. That's why you are getting the timeouts. It will still run although the messages can be annoying. But it may be best to avoid throttling. Perhaps improve cooling, or use a firmware with lower hash rate.

Hi,

I downloaded your client to run with two BFL V1.3. More to come...
I'm running Bitminter Client V1.2.0 (also tested the Beta) and I received the following messages in the report box:

2012.06.15 [09:32] BitFORCE (COM8) ERROR: Extraneous data received: NO-NONCE
2012.06.15 [09:33] BitFORCE (COM7) ERROR: ZFX command timed out. Retries: 0
2012.06.15 [09:33] BitFORCE (COM7) ERROR: Extraneous data received: NO-NONCE

2012.06.15 [09:34] BitFORCE (COM8) ERROR: Extraneous data received: NO-NONCE

When I start the speed rises up to its supposed maximum. Temperature is between 45° and 55° C. After a short while it seems to start throttling and these messages show up.
I'm connected via 100 MBit cable and ping shows < 30ms.
My OS is Win7, latest patches installed. Hardware: e350, 4 GB Ram

Any idea?

Thanks

Version 1.2.0 is out. Thanks to everyone who helped test it, especially Fefox and Phraust. This took a lot more effort than I had anticipated, but now it's done and we have a much improved miner.

Changes from 1.1.2 to 1.2.0:

Support FPGA devices from Butterfly Labs (BFL)
Network subsystem rewritten: fast work download over multiple pipelined
connections to be able to handle higher hash rates. Also yields
fewer rejected proofs of work.
Added minimize/maximize buttons on each device. The compact display
is handy if you have a long list of devices. Remembered across restarts.
The start button of the "total" device now starts only the visible
devices instead of all devices the first time you click it. The next time
you use it to start devices it will resume those you stopped with it,
like it always did. The start button on the status bar works the same.
Adjusted expected hash rate (green zone) for Juniper GPU
Fixed some minor GUI bugs

Try it out:

Windows 8 note:
Version 1.2.0 will not run on current Windows 8 beta versions with current Java releases because of a problem with asynchronous I/O running Java on Windows 8. Until this is fixed in either Java or Windows, if you want to run the miner on Windows 8 you will have to use the previous release:

Anyone planning on running FPGAs on Windows 8 beta?

Nope i got an old Machine with Windows XP for that.

Beta 12 is out, with 2 changes:

Fixed memory leak that would lead to high memory and CPU consumption over time, faster if you had high hash rate
Made the network code more likely to go from 1 to 2 parallel connections

Testing this for 3-4 hours shows very low CPU usage with BFL singles and only about 0.05% rejected proofs of work. (CPU use will be a bit higher on Mac OS X than Windows and Linux because I had to implement a dirty workaround to avoid a bug in the serial port library)

If anyone has a chance to try this on the Raspberry Pi or other ARM-based devices, please let me know. In theory it may work, but I have a feeling the miner will be a tight fit for the low amount of memory on these devices.

There's almost certainly a workaround. PM me if you want me to look at the relevant code.

According to Oracle's bug tracker there's no workaround. I guess the workaround for us is having synchronous networking for running on Windows 8 until they fix this issue.

I could offer older versions (suggested by btc196) or offer a synchronous/asynchronous switch in config (suggested by LordMord). Making older versions available is the quickest solution, and something I was planning on doing at some point anyway. But it does mean new releases won't work on Windows 8 until Microsoft or Oracle implement a fix. Anyone planning on running FPGAs on Windows 8 beta?
