Con Kolivas	9f726400d4	Logic error in the queueing of work ended up generating more stale blocks. There is a small chance that a longpoll is signalled right at the start which would lead to a deadlock so check for first work before restart.	14 years ago
Con Kolivas	594b38b8cb	Fix redefinition of gnu source.	14 years ago

Ycros	9fe2106467	Fixed up using config.h instead of cpuminer-config.h.	14 years ago
Ycros	b645cc9f00	Updated README for building on win32.	14 years ago
Con Kolivas	edd0591e19	Make the number of queued work items configurable and default to 2.	14 years ago
Con Kolivas	131f60a5ee	Move queueing of one request to separate function in preparation for variable length queues.	14 years ago
Ycros	5d301c8ba0	Make a binary load failure build from source.	14 years ago
Con Kolivas	ffdffe77d3	Make sure the work gets attributed to the correct gpu. Add an fflush to stderr to minimise garbled output when multiple threads write at once.	14 years ago
Con Kolivas	86e40ed9c8	Stale block control makes it possible to make 2 threads per gpu the default again.	14 years ago
Con Kolivas	48caf248a7	Check for stale block after failed submission as well.	14 years ago
Con Kolivas	09104ce3e8	Flag the work back to just thread 0 used by all the threads to avoid lots of queued older work for each thread.	14 years ago
Con Kolivas	bed692152f	Get rid of the requirement for a static struct that needs locking to cache work. Make it possible to use the thread id for getting work again. Flag the getwork() function when we have a new block to explicitly discard any cached work when a new block is detected. Store the header of each new work and compare it to blocks we're about to submit to decide if they're stale due to a new block and don't try to submit them. This should significantly decrease the number of rejected blocks.	14 years ago
Con Kolivas	e2fb3e84cb	Queueing all kernel parameters dramatically reduces stale block rates.	14 years ago
ckolivas	7ae9afc40f	Profile points and warning clean ups.	14 years ago
ckolivas	b54a342529	Change default number of threads back to 1. The 2nd just increases the time taken to complete a work item thus increasing stale blocks, despite increasing the rate slightly.	14 years ago
ckolivas	3983f1b9c3	Breaks nvidia building. Roll back for now. Revert "configure.ac, Makefile.am: Allow setting of OpenCL location" This reverts commit a9893d818dac53cb52c2ed06ece59195228f44d9.	14 years ago
Tom Rini	2a8475b5bd	configure.ac, Makefile.am: Allow setting of OpenCL location Add two new configure flags, --with-opencl-libdir and --with-opencl-inc to specify where OpenCL headers and libraries exist. This now adds a test for the OpenCL header file and makes not finding the library or headers a fatal error. Signed-off-by: Tom Rini <trini@kernel.crashing.org>	14 years ago
Con Kolivas	3aa5be4fcf	Reinstate binary kernel loading with fixes. Build binaries with unique filenames from the kernel generated and save them. Try to load this cached binary if it matches on next kernel instantiation. This speeds up start-up dramatically, and has a unique kernel binary for different kernel configurations.	14 years ago
Con Kolivas	88d9d631e3	Use two separate curl instances for submit and get and use separate threads for each to prevent one blocking the other.	14 years ago
Con Kolivas	72baac0889	Clearly delineate the cpus from the gpus for their local data.	14 years ago
Con Kolivas	142576a961	We already have gpu/cpu from id, so use that. Likely the current convoluted code is wrong and leading to segfaults!	14 years ago
Con Kolivas	18f8b0f9a5	Submit work async is still unreliable and only used for cpu mining, so back it out for now.	14 years ago
Con Kolivas	60f0bb19de	Temporarily back out binary building till it's working more reliably.	14 years ago
Con Kolivas	d5d4d1da16	Don't want to free the work data out of the transient structs.	14 years ago
Con Kolivas	a095f0fae2	Broke source generated program. Fix.	14 years ago
Con Kolivas	d100281df3	Make sure correct thread id is in work struct and correct cpu is set for per-cpu data.	14 years ago
Con Kolivas	998d8d45f4	Postcalc hash is already its own thread so work can be submitted synchronously from that.	14 years ago
Con Kolivas	4d73057772	Build binaries with unique filenames from the kernel generated and save them. Try to load this cached binary if it matches on next kernel instantiation. This speeds up start-up dramatically, and has a unique kernel binary for different kernel configurations.	14 years ago
Con Kolivas	973b2199e1	Tidy.	14 years ago
Con Kolivas	2b6e841673	Use a buffer of up to 512 * 4 integers when retrieving work from the GPU. This allows each local thread id to have one slot to put any positive results into, thus making overlapping results far less likely. Thus races will be much rarer, allowing more threads. It should also pick up blocks close to each other more reliably and hopefully decrease the number of rejects and opencl errors. Do the search over the buffer entirely in a separate thread to allow the GPU to stay as busy as possible. Detach threads from themselves to prevent unlucky even where dereferencing occurs by freeing the data that stores the thread info.	14 years ago
ckolivas	6af84770d0	Add spaces to make output clearer.	14 years ago
ckolivas	e1dd27c5c2	Ensure that we don't overflow due to 32 bit limitations.	14 years ago
ckolivas	b38a02bd24	Make the log time hash rate a rolling exponential average so it doesn't fluctuate so dramatically.	14 years ago
ckolivas	08a7821072	Make the log show what the thread is: cpu or gpu and what number.	14 years ago
ckolivas	1dfbe60353	Put sanity limit on work size since some nvidia fail :(	14 years ago
ckolivas	f490143a9a	Add local thread count to info, store hw error count, and make share submission debug only.	14 years ago
Con Kolivas	e016d0c8f3	Increase maximum intensity configurable to 14.	14 years ago
Con Kolivas	dfc52fd543	Make sure we can have gpu and cpu threads running.	14 years ago
Con Kolivas	24a28e29e9	Make it possible to run as a pure cpu miner by setting gpu threads to 0.	14 years ago
ckolivas	e1d01d0635	Minor fixes.	14 years ago
Con Kolivas	6c6bb02b90	There is no point having vectors in the it variable.	14 years ago
Con Kolivas	6374e0fafe	Import the phatk kernel. Enable it only for hardware with amd media ops for now since it crashes nvidia et. al. Fallback to the poclbm kernel for the rest. Try harder to avoid stale blocks around longpoll detecting new blocks.	14 years ago
Con Kolivas	2dbb39444d	Base was being set wrongly meaning we were repeating searches and the rate was actually lower than displayed :( Tweak Ma with new changes. Change default vectors to 2 since it's faster than 4 even when 4 is reported as preferred.	14 years ago
Con Kolivas	c566605195	Tab dainbramage.	14 years ago
Con Kolivas	11c8818558	32 bit only builds one elf, not an elf in an elf, so account for it to be able to bfi int patch properly.	14 years ago
