Dear Sirs.
I kindly ask you to remove completely from the Asteroids@Home project a non-optimized application for 32 bit systems: https://asteroidsathome.net/boinc/apps.php
Look at the page: https://asteroidsathome.net/boinc/apps.php where an unoptimized 32 bit application produces 202 GigaFLOPS, when the optimized one for sse2/sse3 just 4 GF an average.
That is, in fact, that turns out that all users of 32 bit systems are crunching for 6 hours with an unoptimized application. In case you remove it, all users will begin to crunch at sse2/sse3-optimized applications in just 2 hours.
In other words, huge opportunities are being lost doing it.
Or maybe is there any explanation to this?

Interesting observation.... Maybe someone can see what the primary System configuration for the unoptimized app is ? Maybe Win XP on very old systems ?

I have one system receiving these old WU's here is the configuration
CPU type AuthenticAMD
AMD FX(tm)-4130 Quad-Core Processor [Family 21 Model 1 Stepping 2]
Number of processors 4
Coprocessors AMD ATI Radeon HD 2300/2400/3200/4200 (RV610) (256MB) driver: 1.4.1734
Operating System Microsoft Windows 7
Home Premium x86 Edition, Service Pack 1, (06.01.7601.00)
BOINC version 7.16.3
Memory 3326.12 MB
Cache 2048 KB
Swap space 6650.61 MB
Total disk space 931.41 GB
Free Disk Space 874.49 GB
Measured floating point speed 1704.28 million ops/sec
Measured integer speed 6636.7 million ops/sec

Each time a new version of an app is released, the average flops is reset. This explains why many of the app have such low average flops.
The server should do better job checking for optimized apps, then again compared to x86_64 and CUDA, the 32bit is somewhat irrelevant.

Ok the relevant part of the 32bit is from my last post. I have an older 32 bit system running Win 7 32bit on an AMD FX(tm)-4130 Quad-Core Processor. That processor is capable of running the Intel x86-compatible CPU 102.13 axv-win7, sse2-win7 or sse3-win7 optimized applications yet the project is loading the un-optimized base Intel x86-compatible CPU 102.10 WU's to it.

Maybe the base app does not need to go away but instead the logic behind application assignment needs to be looked at.

Computer 43810 for this project.

For consideration
