| Another paper on GW170817 |
Sorry for late notification!
Another research on the famous GW170817 source, which used data obtained from the Universe@Home project, have been published last year. In this study, it was shown that the merger rates of double neutron stars (calculated from one direct observation) stay in contradiction with these inferred from the observations of double pulsars in our Galaxy. The reason behind this tension is the delay time distribution which favours short delays. The study highlights the problem that scientist encounter trying to connect evolutionary predictions and the observations of the first double neutron star merger.

| Results of the first half of the April 2019! |
Dear participants!
April! The Sun's rays are getting warmer, the snow is gone and the green carpet of flower leaves begins to cover the ground again. Among them is Lily of the Valley - a sweet inhabitant of forests, gardens and the symbol of this month! 328 folks of the project received this badge and we send our congratulations to:

| Problem writing CMS job results; please avoid CMS tasks until we find the reason |
Since some time last night CMS jobs appear to have problems writing results to CERN storage (DataBridge). It's not affecting BOINC tasks as far as I can see, they keep running and credit is given. However, Dashboard does see the jobs as failing, hence the large red areas on the job plots.
Until we find out where the problem lies, it's best to set No New Tasks or otherwise avoid CMS jobs. I'll let you know when things are back to normal again.

| New Separation Runs |
Hey everyone,
There was a problem with the previous separation runs that was causing some command lines to overflow. I have changed the bundle size of the new runs, so that shouldn't be a problem anymore. The previous runs have been taken down.
The names of the new runs are:
de_modfit_80_bundle4_4s_south4s_0
de_modfit_81_bundle4_4s_south4s_0
de_modfit_82_bundle4_4s_south4s_0
de_modfit_83_bundle4_4s_south4s_0
de_modfit_84_bundle4_4s_south4s_0
de_modfit_85_bundle4_4s_south4s_0
de_modfit_86_bundle4_4s_south4s_0
These new workunits will crunch a little faster than the previous versions, and credits are assigned accordingly.
Thank you all for your patience during this transition period!

Hello all! We are glad to welcome Formula BOINC in our project. Since the last Sprint, we changed several parameters that should improve server's work. In case you face any difficulties when sending a results report, try to use the option max_tasks_reported: https://rake.boincfast.ru/rakesearch/forum_thread.php?id=93&postid=458#458

| New MilkyWay@home Scientist |
Hey Everyone!
My name is Tom Donlon. I have worked with Prof. Newberg for several years now on a variety of topics involving n-body simulations and the origin of galactic substructure. I will be transitioning to working as a graduate student and will be working on a project involving the separation application for my thesis. As such I will be providing support for this application and learning how to maintain the server from Jake. Please be gentle during my transition.
Thank you for your continued support and I look forward to getting to know all of you.
Best,
Tom

| Long Outage Today |
|
We had to recover the master database on oscar from a backup taken today on carolyn. Oscar is now back to being the master DB and carolyn is once again the replica DB. Things will be a bit slow as the database becomes resident in memory.

| GFN-524288 Mega Prime! |
|
On 18 March 2019, 07:26:42 UTC, PrimeGrid’s Generalized Fermat Prime Search found the Generalized Fermat mega prime:
2733014^524288+1
The prime is 3,374,655 digits long and enters Chris Caldwell's The Largest Known Primes Database ranked 3rd for Generalized Fermat primes and 26th overall.
The discovery was made by Yair Givoni of Israel using an NVIDIA GeForce GTX 960 in an Intel(R) Core(TM) i5-6600 CPU @ 3.30GHz CPU with 16GB RAM, running Windows 10. This GPU took about 2 hours 57 minutes to probable prime (PRP) test with GeneferOCL3. Yair is a member of The Planetary Society team.
The PRP was confirmed prime by an Intel(R) Xeon(R) CPU E3-1240 v6 @ 3.70GHz with 4GB RAM, running Linux Debian. This computer took about 26 hours and 43 minutes to complete the primality test using multithreaded LLR.
For more details, please see the official announcement.

| GPU version bugfix release |
|
GPU versions for all platforms were updated to fix "Error -58" computation error when resuming stopped task.
|
|
| GPU app status update |
So there have been some new developments over the last week. It's both good and bad.
First of all, some history. The reason I waited so long to develop a GPU app is because the calculation was heavily dependent on multi-precision libraries (gmp) and number theoretic libraries (pari/gp). Both of these use dynamically allocated memory which is a big no-no in GPUs. I found a multi-precision library online that I could use by hard coding the precision to the maximum required (about 750 bits), thereby removing the dependence on memory allocations. The next piece of the puzzle was to code up a polynomial discriminant function. After doing this, I could finally compile a kernel for the GPU. That is the history for the current GPU app. It is about 20 to 30 times faster than the current cpu version (depends on WU and cpu/gpu speeds).
But then I got thinking... my GPU polynomial discriminant algorithm is different from the one in the PARI library (theirs works for any degree and mine is specialized to degree 10). So to do a true apples-to-apples comparison, I replaced the PARI algorithm with mine in the cpu version of the code. I was shocked by what I found... the cpu version was now about 10x faster than it used to be. I never thought I was capable of writing an algorithm that would be 10x faster than a well established library function. WTF? Now I'm kicking myself in the butt for not having done this sooner!
This brings mixed emotions. On one side, it is great that I now have a cpu version that is 10x faster. But it also means that my GPU code is total crap. With all the horsepower in a present day GPU I would expect it to be at least 10x faster than the equivalent cpu version. Compared with the new cpu version, the gpu is only 2 to 3 times faster. That is unacceptable.
So the new plan is as follows:
1. Deploy new cpu executables. Since it's 10x faster, I will need to drop the credit by a factor of 10. (Credits/hour will remain the same for the cpu but will obviously drop for the GPU)
2. Develop new and improved GPU kernels.
I don't blame the GPU users for jumping ship at this point. Frankly, the inefficiency of the current GPU app just makes it not worth it (for them or the project).
For what it's worth, I did have openCL versions built. Nvidia version works perfectly. The AMD version is buggy for some reason, as is the windows version. Since I will be changing the kernels anyways, there is no point in debugging them yet.

| The Drake Equation Revisited |
|
Richard Lawn has given us a new SETI Perspectives article to think about. This one is about the Drake Equation.

|
| Another crash |
This time the primary database machine crashed and hasn't automatically recovered. We've fallen back to the replica machine, and the only symptom should be a few extra hours of outage.
I'm glad we have the replica.

| Hardware - long-term plans |
Due to the long-term plans I have in the goofyxGrid classification, I would like to make some changes that have a significant impact on the stability of the project and its resistance to failures.
My long-term plan regarding the equipment assumes securing the project as much as possible.
1. buying 3 servers
2. creation of the CEPH cluster, 2 machines resistant to death
3. goofyxGrid virtualization on proxmox
4. creation of the HA cluster, which is resistant to the death of 2 machines
5. Purchase UPS specialty for the above
I do not conceal that I am counting on your support, for example: patronite, paypal, etc.
In case of using used servers, the cost of such a 3 server cluster (after adding 8x HDD/SSD disks and 128GB RAM to each one) is about 3-3,5k $
This is a lot of cash, however, it will have a drastic impact on the security level of the project.
