Yes, this was only testing the current plan_class with Cuda111 while there are some different things in config. It looks like the app was not compiled with cc7 but cc6. For cc10 we will have a separate app of course.

your current cuda120 app seems to support 5.0 (maybe, dont have any to test), 6.0, 6.1, 7.5, 8.6, 8.9, neglecting 7.0.

it seems clear that the project is only looking at the driver version or embedded cuda version for deciding which app to send. using an app_config WILL NOT WORK.


could you recompile the cuda120 app to include ALL CCs and add in 7.0?

Need to ask, windows and linux can be different.

I'm talking about the Linux cuda120 app

all cuda120 tasks error out on my V100s. in the same way that crash's P100s were erroring.

did you omit support for CC 7.0 (titan V and V100 at this CC level)? as i pointed out before you need to explicitly add support for every CC level individually.

We can try to use cuda100 WUs with an app_config. Thats the oldest app which we are running.

<app_config> <app_version> <app_name>TF</app_name> <plan_class>cuda100</plan_class> <min_gpu_ram_mb>384</min_gpu_ram_mb> <gpu_ram_used_mb>384</gpu_ram_used_mb> <gpu_peak_flops_scale>0.22</gpu_peak_flops_scale> <cpu_frac>0.01</cpu_frac> </app_version> </app_config>

tried it. didnt work. this app config does not work. it will not limit the project to only getting the cuda100 app.

same results on a Titan V (same cc-7.0), instant error.

I'm guessing the problem is how the app was compiled without cc 7.0 support.

We can only try this

<app_config> <app_version> <app_name>TF</app_name> <plan_class>cuda111</plan_class> <min_gpu_ram_mb>384</min_gpu_ram_mb> <gpu_ram_used_mb>384</gpu_ram_used_mb> <gpu_peak_flops_scale>0.22</gpu_peak_flops_scale> <cpu_frac>0.01</cpu_frac> </app_version> </app_config>

Or the app was not compiled with cc7, P100 was working, right?

this method of using an app_config to try to force what app gets sent, do not work. i've never had this work reliably and it didnt work for crashtech when you suggested it last time. an app config is designed to enact some configuration on apps that are already downloaded. it does not impose any influence on what the project server actually sends me.

i think your app was not compiled with CC 7.0 support. and if you didn't do it on the latest app, I would guess you didnt do it on the older apps either.

P100 works as far as I know. but that's because you fixed it by recompiling the app to include the CC 6.0 support.

when compiling cuda apps you cannot just put a minimum value. you need to put ALL values that you want to support. to support everything from CC5.0+ you need to explicitly state every version (5.0, 5.2, 6.0, 6.1, 7.0, 7.5, 8.6, 8.9)

5.0 - GM100 Maxwell
5.2 - GM200 Maxwell
6.0 - GP100 Pascal
6.1 - GP102+ Pascal
7.0 - GV100 Volta (Titan V and V100)
7.5 - TU102+ Turing
8.0 - GA100 Ampere
8.6 - GA102+ Ampere
8.9 - AD102+ Ada Lovelace
9.0 - GH100 Hopper

and you're going to have to recompile again in the future to add 10.x something if you want to support the upcoming Blackwell GPUs.
