Con Kolivas 00de8225 2011-06-26T15:28:33 Upper limit should be -hashes.
Con Kolivas c29a4322 2011-06-26T13:45:38 Only update the hashmeter once per second from gpu mining threads.
Con Kolivas b6ae1db8 2011-06-26T10:53:16 The submit_lock is not required nor helpful.
Con Kolivas ead1281b 2011-06-25T18:27:56 Cleanup of return codes.
Con Kolivas f6486efb 2011-06-25T13:40:42 Make the getting of work asynchronous from the mining threads requests by always having one work item queued. This prevents drops in hash rates when getting work from a pool that is slow to respond. Use a local static struct work in get_work that is used to queue one extra work item.
Con Kolivas 0cef8f8d 2011-06-25T12:50:15 Default scan timeout of 5 seconds is way too short leading to abandoning blocks too early and being seen as an "inefficient" miner. Increase it to 60.
Con Kolivas d1c0cccd 2011-06-26T09:09:07 Show correct GPU from thread number.
Con Kolivas d2cb012f 2011-06-25T10:07:29 Detach the thread once created so we don't have to explicitly try and join it.
Con Kolivas 295ef0f9 2011-06-25T21:47:16 Discard accumulated work when longpoll indicates a new block.
Con Kolivas 063adc64 2011-06-26T12:59:15 Implement runtime selectable numbers of GPU threads and rename CPU threads option.
Con Kolivas f1114992 2011-06-26T09:07:52 Implement a potentially variable number of threads per gpu, setting it to 2 for now.
Con Kolivas f44e8fac 2011-06-25T20:56:17 Curl appears to be not thread safe so only have one curl open at a time.
Con Kolivas 343ae851 2011-06-25T20:38:40 Intensity 5 is too high for a normal desktop causing unacceptable lag so change the default to 4.
Con Kolivas 08f56f5f 2011-06-26T08:55:53 Set default CPU threads to 0 if GPU mining.
Con Kolivas 88e2cf7b 2011-06-25T20:22:23 Initialise libcurl properly.
Con Kolivas 656b485d 2011-06-25T18:58:59 Make the worksize and vector width configurable.
Con Kolivas b7a17753 2011-06-25T09:56:37 Make a separate thread for work submission that returns immediately so that miner threads aren't kept waiting when submitting results to slow pools.
ckolivas e8f4eead 2011-06-24T16:24:53 Use total mhashes as a counter to prevent 32 bit overflows.
Con Kolivas 852e78e7 2011-06-23T22:09:49 Fix mutex unlocking with only one thread and opt_log_interval.
Con Kolivas 70f73576 2011-06-23T21:58:46 Make the output display the 5 second and total average Mhash/s. Make the log interval configurable.
Con Kolivas debe7776 2011-06-23T21:23:46 Use cpu_from_thr_id when binding threads.
Con Kolivas 4cd5f47e 2011-06-23T21:09:22 Revert "Multiple compiler warning fixes." This reverts commit a5cbfbde2610e9f60e14b41a4e0595bcb34c772a. Broke.
Con Kolivas 88761e6c 2011-06-23T21:04:29 Multiple compiler warning fixes.
ckolivas 19eea906 2011-06-23T17:50:37 Implement code detecting max work size and optimal vector width. Use this to patch the kernel to suit the idea values for the card. Then use these values when invoking the kernel.
ckolivas 237a5067 2011-06-23T15:28:12 Skip trying to start thread of GPUs that don't successfully initcl().

Con Kolivas 932ff72f 2011-06-22T23:35:23 The gpuminer thread uses very little cpu and needs to keep the gpu busy with as few delays as possible. Don't nice it.
Con Kolivas f54d2cc0 2011-06-22T23:07:30 Make poclbm use 4 vectors and decrease worksize to keep pipelines fullish. Make it possible to have 0 CPU threads and update docs. Fix counter with no cpu threads.
ckolivas 66240481 2011-06-22T15:39:27 Fix deref.
ckolivas fa2f6b19 2011-06-22T13:54:06 Unwind.
ckolivas f7926088 2011-06-24T10:55:05 Limit intensity to 10. Anything larger overflows. Simplify test for new work.
ckolivas 79fec01a 2011-06-22T12:27:57 Remove the input buffer and just pass args to the kernel as per plugin design.
Con Kolivas f117675a 2011-06-22T10:15:23 Optimise work loop to make cl calls asynchronous where possible.

ckolivas 51817422 2011-06-14T14:09:10 Cope with older linux kernel headers that don't have the newer scheduling policies defined.
Con Kolivas 0a8ac14c 2011-06-12T14:26:26 Forgot the else.
Con Kolivas 4f8045c2 2011-06-12T11:40:15 Only increase solutions count when confirmed true.

Move priority change to worker threads only. Detect number of CPUs and set default number of threads == CPUs. Add scheduling policy change to worker threads to SCHED_IDLE first and fallback to SCHED_BATCH on linux. Don't error when failing to set priority. Add CPU affinity and bind worker threads to CPUs when number of threads is a multiple of number of CPUs. Update NEWS with changes.

Jeff Garzik e8ee4cb0 2011-02-03T00:54:03 Add --retry-pause, to set length of pause time between failure retries
Jeff Garzik 714c0fd7 2011-02-03T00:46:55 Continue scanhash, even if high 32 bits are zero. Previously, we would stop the scan if the high 32 bits of the hash were zero, as a quick shortcut for testing the full hash. If this quick test succeeded, we would pass the work to the server for full validation. Change this logic to perform full validation inside minerd, so that work may be resumed more quickly if hash > target.
