On my SuSE Linux Leap 42.2 box I am using nVidia driver 384.59 provided by SuSE and it works perfectly on my GTX 750 Ti board. GPU temperature is 50 C.

After Eddington's confirmation of General Relativity this theory has received another from the observation of three stars circling the massive black hole Sagittarius A made by the European Southern Observatory Very Large Telescope in Chile. All three orbits follow closely the prediction of General Relativity and not that of Newton's theory. This is another check of Einstein's theory.

I had downloaded 7.2.42 from OpenSUSE and the BOINC manager would not start saying that some libraries were missing. Then I went to the BOINC site, downloaded 7.4.22 and it worked out of the box. I am running SuSE Leap 42.2 on both Linux machines, and also use VirtualBox 5.1.26 to run LHC@home tasks.

It is running two tasks, one Einstein@home CPU and one climateprediction.net on the E-450 PC with SuSE Linux Leap 42.2. It is also running two Einstein@home CPU tasks on the Opteron 1210, but it has also run one Einstein GPU task, which is very demanding, on the GTX 750 Ti. It can run 2 CPU tasks and one SETi@home GPU task, while Einstein@home GPU tasks allow only one CPU task. That is good enough for me, both E-450 and the Opteron 1210 have only 2 cores.

I have installed BOINC 7.4.22 on both my Linux boxes, and it works. The HP laptop has no graphic board, but the 2008 vintage SUN workstation has a GTX 750 Ti board and runs both SETI@home and Einstein@home GPU tasks with no problem. Linux is OpenSuSE Leap 42.2.

I've been able to read on the Le Scienze page an article of "Symmetry" magazine which said that researchers of Fermilab have completed a survey of 26 million galaxies using a Dark Matter Camera mounted on a 4 meter telescope of the Interamerican Observatory at Cerro Tololo, Chile. They used the method of looking for gravitational lensing, a result of General Relativity, to look for dark matter. Their result follows closely that of the Planck spacecraft of European Space Agency and gives a result of dark matter being 26% of total Universe mass.

The Virgo French/Italian interferometer near Cascina, Pisa, has started taking data today according to a press release of the Istituto Nazionale di Fisica Nucleare which manages it. It will go on until August 25, the end of the second run of the LIGO interferometers. A detection by three instruments instead of two should be able to pinpoint the source with more accuracy. I am not sure if Virgo will give data to Einstein@home but I hope so.

My HP laptop running SuSE Linux Leap 42.2 refused to boot last evening after a crash. I have run all BIOS tests on it and there is no problem on the RAM and the disk. Then I tried to install Leap 42.3 on it and it stops at "searching system files". Then I left it running memtest all night and tried again. No luck. Then I installed Solaris 11.3 from a DVD and had no problem. But Solaris has no BOINC client so I can't run any BOINC project. It was running SixTrack of LHC@home. Sorry.

After the Creators Update my Windows 10 Home edition PC is able to crunch only SETI@home and SETI Beta tasks, both on CPU and GPU ( a GTX 1050 Ti). All else fails. Bu I have two older Linux boxes. One runs the SixTrack tasks of LHC@home, the other the Einstein@home tasks, both CPU and GPU on a GTX 750 Ti. Its driver has been updated by OpenSuSE and is now 384.59.

On the site of the Televisione della Svizzera Italiana, which I see on Iinternet, there was an interview with a glaciologist of the Zurich Polytechnic Institute who said that the Alpine glaciers are disappearing within this century. I can confirm that the glacier of Marmolada, the highest peak of Dolomiti mountains, which I had climbed in 1960, in the year 2000 was reduced to one half. Poor mountains, without their glaciers are reduced to rubble.
