I have 4 core processor, 1 my processor is desapear, now I am crunching with 3 core.I unistall and again install Boinc, again I have only 3 processor.Whate happen ? , how I can fix it ?

There is no problem with your 4 core processor.  One core certainly hasn't 'disappeared' :-).  Your computers list clearly shows that BOINC sees all 4 processors.  If not all four are crunching, it would most likely be something to do with how you have set your computing preferences.  Please check what you have set for how many cores BOINC is allowed to use (Use at most x% of the processors).  If 'x' is 75% instead of 100% then you would only ever see 3 CPU tasks running.

It is hard to know what is going on because you seem to have aborted all tasks that you have received over the last several days.  Your machine doesn't seem to be requesting any CPU tasks at the moment.  It is requesting GPU work but the last contact log shows that the server is refusing to send any for FGRPB1G because your GPU doesn't have OpenCL capability or (more likely) that the necessary driver components are not installed.  Please be aware that the only GPU work available is for FGRPB1G (which needs OpenCL) since the Arecibo GPU work (BRP4G - which used CUDA) for discrete GPUs has finished, at least for the moment and perhaps permanently.

Because there have been lots of changes with the Einstein project in recent months, perhaps it is because of these that you are having difficulties.  Do you know all the things that have changed?  There are no more BRP6 tasks or BRP4G tasks for the GPU.  There are new CPU tasks for continuous gravity wave detection but the type that would have run on your machine have now finished.  There are new tasks for both CPU and GPU for the Fermi Gamma Ray Pulsar searches (FGRPB1 and FGRPB1G) and there have been quite a number of changes to the apps for these.  If you would like to continue crunching with your machine you need to look at the two FGRP searches only at the moment until something new comes along.  Unfortunately, the NVIDIA GPU version using OpenCL (particularly for older GPUs) is quite slow but there are indications that a CUDA version may come along in the future.  This would likely be better.  A GPU task using the NVIDIA OpenCL app always needs a full CPU core as well as the GPU.

If you would like assistance with setting up or further explanation about the options, please ask.

 

Cheers,
