AP包专门针对AVX指令做了优化。要打开AVX指令需安装win 7 SP1。
具体介绍：
Lunatics are pleased to announce the availibility of the v0.40 installer in the Lunatics main download area
Please take care you use the right installer (32/64 bit) for your system.
Should you have any questions or problems - ask! Post in this thread or open a new one.
New in this installer:
Update of all Astropulse applications to support AP v6.01.
How to use the installer:
For the CPU applications, you need to know what your CPU supports. Either check the Boinc startup messages or check with CPU-Z downloadable from http://www.cpuid.com
Tick or untick CPU AP and MB applications as desired. Tick CUDA MB if desired.
Tick ATI (OpenCL) AP or MB if/as desired.
More details further down.
NB We use default values throughout the app_info.xml. If you have previously installed optimised applications and manually edited app_info.xml (e.g. <count> for multithreading GPUs, <flops>, <cmdline> for ATI) you WILL lose those edits on running the installer and have to redo them. You may wish to make a note of them. You will also lose all other manual edits to app_info.xml such as beta applications.
Known issues - general:
The installer is supposed to shut down the BOINC client whilst leaving the Manager running - noticable from the red 'disconnected' dot in the tray. After finishing the BOINC client should restart and the red dot vanish when the Manager reconnects. This make take a few minutes. On some systems however this fails to work. Please ensure BOINC has restarted.
Advanced users only: If you know you are going to edit app_info.xml, it may be easier to shutdown and restart BOINC manually, so you can get the changes into app_info.xml before the restart.
CPU MB apps - AKv8b2
If you have any doubt at all about what instruction sets your CPU supports, download CPU-Z from http://www.cpuid.com/softwares/cpu-z.html You will usually find that the SSSE3x application is fastest on the Intel processors which support SSSE3x, except on dual-core CPUs with especially fast memory subsystems,where SSE4.1 may be faster.
However, we have an indication, that on Intel i3, i5 and i7 processor series SSE3 may be the fastest variant at most angleranges. The effect is smallest with VHAR (shorties).
CPU AP apps - r555/r557
The new r555/r557 AP applications support AP v6.01 and v5.05 work.
If your CPU is only capable of SSE choose the r555 SSE application.
If your CPU supports AVX (Intel Sandybridge and AMD Bulldozer, Windows 7 SP1) choose the r557 SSE2 build as it is faster.
If you have a CPU with SSE2 and above but not AVX the r557 MAY be faster.
We have indication that on most hosts r557 is faster but no guarantees.
As always - your mileage may vary.
NVidia GPU (CUDA) app - x41g_cuda32
For compatible cards see http://developer.nvidia.com/cuda-gpus
Requires minimum CUDA 3.2 capable NVidia driver: 263.06 (260.99 on notebooks)
Download drivers from http://www.nvidia.com/Download/Find.aspx?lang=en-us (or your national equivalent). We recommend you avoid driver versions 295.73 and 296.10, which are not supported at some other BOINC projects.
Should run on all NVidia CUDA cards with at least 512MiB video RAM.
Actual free memory required is in the region of 200-235MB, depending on driver and OS flavour.
Running on a 256MiB card is just possible, but you will have to free up as much VRAM as possible, e.g. by disabling Aero.
Used video RAM can be checked with GPU-Z downloadable from http://www.techpowerup.com/downl ... p_GPU-Z_v0.6.0.html
Watch closely on GPU-Z and in BOINC manager if the application finds enough memory.
Symptoms of insufficient memory are
- in BOINC manager: tasks start up and run a few seconds then go to 'waiting to run' and the next task tries to start
- on GPU-Z: the sensor for memory shows used VRAM ramping up and almost immediately dropping again.
In this case, there may be a BOINC bug putting the app in an infinite loop while it waits for more memory.
If you don't have enough memory, set BOINC to NNT, abort tasks and uninstall the CUDA application by rerunning the installer with CUDA MB UNticked.
If in doubt ask for help on the SETI Number Crunching forum.
To multithread on Fermi cards, find all instances of <count>1</count> in app_info.xml and decrease to 0.5 or 0.3 to run two or three tasks in parallel.
Again, if you are uncertain of how to do this correctly, ask on the above mentioned forum. 'Your mileage may vary' - it depends on your specific system which count will give the highest throughput.
x41g has improved reliability, stability and accuracy over x38g.
x41g_cuda32 has been tested with and is safe to use on Kepler.
ATI MB apps - r390; AP apps - r555
We offer the MB application in two different variants, depending on card:
plain - for most HD4xxx owners and those with HD5xxx and HD6xxx cards who suffer from driver incompatibilities.
HD5 - for most if not all owners of HD5xxx GPUs and HD6xxx GPUs.
The ATI MB application will not work on ATI cards with workgroup size 128 (e.g. HD43xx). To check workgroupsize run CLinfo, downloadable (at present) from {http://boinc.berkeley.edu/dl/clinfo.zip}
It will, however, probably work on HD53xx & HD63xx with workgroup size 128.
If you have problems running the HD5 flavour (anything from reduced performance to BSOD), you should run the plain variant.
The recommended apps (r555 for Astropulse, r390 for MultiBeam) need OpenCL support from the ATI driver - for recent driver versions, look for a driver *with* APP or OpenCL listed. For compatible drivers see http://support.amd.com/us/gpudownload/Pages/index.aspx
For cards, see http://developer.amd.com/gpu/AMD ... rCompatibility.aspx
On most systems GPU-Z (see above) will tell you if your setup supports OpenCL.
Minimum required driver: Something that is OpenCL capable. You can check with GPU-Z (see above).
Catalyst 10.7b with SDK
Catalyst 10.10 Accelerated Parallel Processing (APP) Technology Edition
The following drivers are known to be incompatible with the app:
11.10 and 11.11.
On some drivers the app shows increased CPU usage.
Drivers from 11.12 onwards work.
First official driver for HD7xxx is 12.3.
For cards without OpenCL support (from HD2xxxx on) use the 'hybrid' r555 Astropulse application. NB this is a combined CPU/GPU application and will only use the GPU for some of the calculations, while doing the rest on a CPU core.
Minimum driver version Catalyst 9.x.
NB using this installer will give you arbitrary default cmdline parameter entries.
If you are already running ATI applications: Make a note of what numbers you are using to be able to restore to those values PRIOR to running the installer.
This also applies to setting the <count> variable according to your -instances_per_device variable for multithreading. (i.e. a <count> setting of 0.5 requires a -instances_per device setting of 2)
The Hybrid AP application uses about 80% of a CPU core and does only about 20% of the calculations on the GPU. Parameters have been choosen to reflect this usage. However present BOINC can not reserve '0.8' of a CPU core and therefore reserves none. This means your CPUs will be overcommitted and runtimes and DCF will suffer. You do increase the overall output though. |
