A new App for Intel-based Macs is available on our Beta Test Page. It was built from the same code as the 4.58 Linux App, and should be way faster than our current official 4.46. How much faster exactly is left to you to find out.

Happy Testing!

There is none (yet). Some part is coded in Assembler, which won't work on PPC.

RE: Big improvements for me

Big improvements for me too. From 18,000 CPU Secs to 4,200 CPU Secs ...
BUT:
Whereas I was claiming 71.00 credits before, and being granted about 43/44 ...
I am now only claiming 16.20 !!!
HELP!!!!!
What is going wrong?


Nothing. The claimed credit is roughly benchmarked_flops * cpu_time_used, so if you only need 1/4 of the time, the claimed credit will also go down by the same amount. Your granted credit, however, will probably not go down that much.

The next analysis run (starting in roughly 2 weeks) will probably be set up in a way that a fixed credit is granted for each Task, regardless of the time needed to crunch it.

RE: Is the assembler parts

Is the assembler parts of the test application based on Akos C or U version? Since all Intel Mac’s are very resent, they should all be SSE3 compatible, right?


The code has been developed with �Akos, but it is not identical to any of his Apps. Currently only SSE commands and registers are used.

I see that the anonymous

I see that the anonymous platform scheme we use for public Beta Test is badly prepared for the transition to S5R1 we're doing now.

With that transition I'd consider the Beta Test to be over - and successful. The Apps we will use for S5R1 are almost the same than the ones we had in public Beta Test, the improved science code is actually identical, thus the new Apps will be precisely as fast as the Beta Test Apps.

Thank you for all your help, this was incredibly useful!

However the Beta Test Apps are lacking some features we found we need for the new run, and thus can't be used for the new Workunits. There is a bit of S4 work left, but no guarantee that the scheduler will try to give it to your machine. So

- if you want to keep your machines busy regardless of the type of work processed, just remove the app_info.xml file (and restart the client). You will download the new App for the new work, and the old official App for the old S4 work.

- if you prefer to do the old S4 work while it is available and risk your machine runs dry, keep the app_info.xml until there's no more S4 work left (we'll add an entry for that on the server status page).

- if you want to live risky and enjoy it, try the following: remove the app_info.xml, but keep a copy of the Beta App executables somewhre outside the project directory. Restart the client. After getting S4 work and having downloaded the old official App, stop the client again and replace the executables of the official App with the backups of the Beta Test App. Then start the client again. There's no guarantee that this will fool all clients on all machines, but it should work most of the time and finish the S4 work with the speed of the Beta Apps.

Have fun!

yep. right question.

The S5 application you will download with your first S5 work (once you have removed the app_info.xml) named einstein_S5R1_4.03 is almost identical to the 4.59, just got added the new features we need for S5R1, and is equally fast.

So what's the problem?
