ckolivas b198423d 2012-06-26T16:01:06 Don't keep rolling work right up to the expire= cut off. Use 2/3 of the time between the scantime and the expiry as cutoff for reusing work.
ckolivas 6e80b63b 2012-06-26T15:43:03 Revert "Increase the getwork delay factored in to determine if work vs share is stale to avoid too tight timing." This reverts commit d8de1bbc5baa416148f50938cfde28a5261cb0e1. Wrong fix.
ckolivas d8de1bbc 2012-06-26T13:07:08 Increase the getwork delay factored in to determine if work vs share is stale to avoid too tight timing.

Con Kolivas 17ba2dca 2012-06-25T10:51:45 Logic fail on queueing multiple requests at once. Just queue one at a time.

Con Kolivas 63dd598e 2012-06-25T00:42:51 Queue multiple requests at once when levels are low.
Con Kolivas 757922e4 2012-06-25T00:33:47 Use the work clone flag to determine if we should subtract it from the total queued variable and provide a subtract queued function to prevent looping over locked code.
Con Kolivas 49dd8fb5 2012-06-25T00:25:38 Don't decrement staged extras count from longpoll work.

Con Kolivas 32f52721 2012-06-25T00:03:37 Revert "With better bounds on the amount of work cloned, there is no need to age work and ageing it was picking off master work items that could be further rolled." This reverts commit 5d90c50fc08644c9b0c3fb7d508b2bc84e9a4163.
Con Kolivas 5d90c50f 2012-06-24T23:38:24 With better bounds on the amount of work cloned, there is no need to age work and ageing it was picking off master work items that could be further rolled.
Con Kolivas 47f66405 2012-06-24T23:10:02 Alternatively check staged work count for rolltime capable pools when deciding to queue requests.
Con Kolivas efa9569b 2012-06-24T22:59:56 Test we have enough work queued for pools with and without rolltime capability.
Con Kolivas 1bbc860a 2012-06-24T22:47:51 Don't count longpoll work as a staged extra work.
Con Kolivas ebaa615f 2012-06-24T22:16:04 Count extra cloned work in the total queued count.
Con Kolivas 74cd6548 2012-06-24T22:00:37 Use a static base measurement difference of how many items to clone since requests_staged may not climb while rolling.
Con Kolivas 7b57df11 2012-06-24T21:58:52 Allow 1/3 extra buffer of staged work when ageing it.
Con Kolivas 53269a97 2012-06-24T21:57:49 Revert "Simplify the total_queued count to those staged not cloned and remove the locking since it's no longer a critical value." This reverts commit 9f811c528f6eefbca5f16c92181783f756e3a68f.
Con Kolivas a05c8e3f 2012-06-24T21:57:18 Revert "Take into account total_queued as well when deciding whether to queue a fresh request or not." This reverts commit b20089fdb70a52ec029375beecebfd47efaee218.
Con Kolivas 750474bc 2012-06-24T21:56:53 Revert "Further simplify the total_queued counting mechanism and do all dec_queued from the one location." This reverts commit 790acad9f9223e4d532d8d38e00737c79b8e40fb.
Con Kolivas d2c1a6bd 2012-06-24T21:56:36 Revert "Make sure to have at least one staged work item when deciding whether to queue another request or not and dec queued in free work not discard work." This reverts commit c8601722752bcc6d3db7efd0063f7f2d7f2f7d2a.
Con Kolivas c8601722 2012-06-24T21:52:07 Make sure to have at least one staged work item when deciding whether to queue another request or not and dec queued in free work not discard work.

Con Kolivas ded16838 2012-06-24T20:48:02 Add the getwork delay time instead of subtracting it when determining if a share is stale.
Con Kolivas b5757d12 2012-06-24T20:45:47 Don't count getwork delay when determining if shares are stale.
Con Kolivas 9f811c52 2012-06-24T20:38:40 Simplify the total_queued count to those staged not cloned and remove the locking since it's no longer a critical value. Clone only anticipated difference sicne there will be a lag from the value returned by requests_staged(). Keep 1/3 buffer of extra work items when ageing them.
Con Kolivas 411784a9 2012-06-24T19:53:31 As work is sorted by age, we can discard the oldest work at regular intervals to keep only 1 of the newest work items per mining thread.
Con Kolivas 359635a8 2012-06-24T18:44:09 Only roll enough work to have one staged work for each mining thread.
Con Kolivas 0c970bbd 2012-06-24T18:22:20 Roll work again after duplicating it to prevent duplicates on return to the clone function.
Con Kolivas 610302af 2012-06-24T18:10:17 Abstract out work cloning and clone $mining_threads copies whenever a rollable work item is found and return a clone instead.
Con Kolivas a8ae1a43 2012-06-24T14:38:31 Rolltime should be used as the cutoff time for primary work as well as the rolled work, if present.
Con Kolivas c20a89d9 2012-06-24T14:20:29 Take into account average getwork delay as a marker of pool communications when considering work stale.
Con Kolivas f32ffb87 2012-06-24T13:20:17 Work out a rolling average getwork delay stored in pool_stats.
Con Kolivas 4e60a62a 2012-06-24T12:55:56 Getwork delay in stats should include retries for each getwork call.
ckolivas 6a45cbbd 2012-06-23T23:45:08 Merge branch 'master' of https://github.com/ckolivas/cgminer
ckolivas c5a21fab 2012-06-23T23:43:22 Extend nrolltime to support the expiry= parameter. Do this by turning the rolltime bool into an integer set to the expiry time. If the pool supports rolltime but not expiry= then set the expiry time to the standard scantime.
Con Kolivas f70577b0 2012-06-19T04:38:49 Merge pull request #229 from luke-jr/modminer_primary modminer: Don't delay 2nd+ FPGAs during work restart
Luke Dashjr 1215da39 2012-06-18T05:51:09 modminer: Don't delay 2nd+ FPGAs during work restart Add primary_thread boolean to threads to identify a single one as the "primary" thread for shared-resource multithreading. This is needed since ModMiners use multiple threads to interface with independent hashing components.
Paul Sheppard 7ae22e21 2012-06-16T20:24:40 Disable OpenCL code when not available.

Con Kolivas 83bf9f43 2012-06-14T20:53:07 can_roll and should_roll should have no bearing on the cycle period within the miner_thread so remove it.
Con Kolivas ceec3f83 2012-06-14T20:36:17 Check for strategy being changed to load balance when enabling LPs.
Con Kolivas b0de3ede 2012-06-14T17:28:24 Check that all threads on the device that called get_work are waiting on getwork before considering the pool lagging.
Con Kolivas 44f5d55d 2012-06-14T17:16:37 Iterate over each thread belonging to each device in the hashmeter instead of searching for them now that they're a list.
Con Kolivas 6e2c12ee 2012-06-14T16:11:29 When using rotate pool strategy, ensure we only select from alive enabled pools.
Con Kolivas 79f4b570 2012-06-14T15:58:18 Start longpoll from every pool when load balance strategy is in use.
Con Kolivas dbe9056d 2012-06-14T15:42:43 Add mandatory and block fields to the work struct. Flag any shares that are detected as blocks as mandatory to submit, along with longpoll work from a previously rejecting pool.

Con Kolivas 598476ca 2012-05-30T18:02:00 Merge pull request #204 from kanoi/icarus-timer Icarus: high accuracy timing and other bitstream speed support
Con Kolivas 624948e2 2012-05-31T09:44:51 Open a longpoll connection if a pool is in the REJECTING state as it's the only way to re-enable it automatically.
Con Kolivas 2586bda5 2012-05-31T09:40:32 Use only one longpoll as much as possible by using a pthread conditional broadcast that each longpoll thread waits on and checks if it's the current pool before opening its longpoll connection.

Con Kolivas 4987958e 2012-05-04T20:10:38 Add a temporarily disabled state for enabled pools called POOL_REJECTING and use the work from each longpoll to help determine when a rejecting pool has started working again. Switch pools based on the multipool strategy once a pool is re-enabled.

Con Kolivas 5081c182 2012-05-03T09:24:25 Limit the number of curls we recruit on communication failures and with delaynet enabled to 5 by maintaining a per-pool curl count, and using a pthread conditional that wakes up when one is returned to the ring buffer.

ckolivas 5cf4e188 2012-05-02T11:17:06 Increase pool watch interval to 30 seconds.
ckolivas 85008a78 2012-05-02T10:12:07 Reap curls that are unused for over a minute. This allows connections to be closed, thereby allowing the number of curl handles to always be the minimum necessary to not delay networking.
Con Kolivas ec3d0570 2012-05-01T21:07:16 Use the ringbuffer of curls from the same pool for submit as well as getwork threads. Since the curl handles were already connected to the same pool and are immediately available, share submission will not be delayed by getworks.
