1) Questions and Answers : Wish list : LINUX@ARM app and wrapper (Message 4748)

Well my local benchmarks were done on the same short WU smina-mol2_A1-smina-mol2-10_config-4a55_sdfActives_PI3Kactives-chunk-0002657.sdf_02657_3995.in, there I did see the 10% lead for 64bit...

The C2 has settled on the faster 64bit app, seems the server side scheduler (?) has recognized there is no use sending out WUs for the slower app to this host.

My C2 receives WUs for both apps (32/64bit), BOINC estimates for 32bit is 00:38:07 and for 64bit 00:31:20.
When I benchmarked a short WU with both apps, the difference was only a 10% advantage for the 64bit application though.

Good stuff, my C2 and RPi3 are crunching.
So far 4 WUs completed in 800 seconds / 13:33min on the Pi, guess I was lucky with those, no chance the Pi's A53 beats the A15 in the XU4 otherwise...
I would expect though the A15 to perform at least 2x as fast as the A7 cores in the XU4.

edit:

btw, the aarch64 wrapper is 32bit, right?

Does the wrapper do any other magic beyond unpacking the Zip and running smina with the right parameters? I was thinking of replacing it with a shell script that does the same and could eg. run smina with --cpu 4 or like that...

Great, that looks promising!

I have attached a RPi3 and a C2 for now, waiting for the release :-)

Compiling on the C2, thats what I wanted to hear ;-)

Those compile orgies require quite a bit of patience, take your time.
Reminds me of compiling KDE on an Ultra Sparc II 400MHz running Gentoo, that took almost 1.5 days if I remember well...

Thanks Krzysztof!

Any idea whether these apps could benefit from a 64bit/ARMv8a build?

I haven't had any smina WUs yet, just Vina.
That makes comparisons onto the efficiency of the app rather difficult I fear.

Hi there,

I noticed you are using Autodock Vina to do the actual crunching. Vina 1.1.2 (same version that you provide) is also included in the Ubuntu repository on my Odroid C2 ARM boards, hence easily available.
Doing some tests with a slot copied from my i7 3770, the Intel needs 3:38 minutes, the C2 9:27 minutes and with 4 threads only 3:10 minutes.
Given the cost of such a board, I'd say that is pretty competitive.

Any chance this could be used and the wrapper or its source be provided for Linux@ARM?


Thanks :-)
