can we run multiple tasks at at the same time on our gpu's?

What's the point? Tasks on the GPU use 100% of the resources, so parallel processing will be no different from sequential processing, and may even be slower. In addition, more CPU and VRAM resources will be required at the moment. Please correct me if I'm wrong. |

Depends on the gpu in use as well as the efficiency of the application. If running a single task doesn't utilize 100% of the gpu resource, then running another 1, 2, 3 and even 4 concurrent tasks on the gpu may be necessary to fully involve the gpu. You reach diminishing returns when the elapsed time for a returned task is longer than the single task elapsed time. IOW total elapsed time for concurrently run tasks / number of tasks should always be faster than the single run tasks. If that gets greater then reduce the number of concurrently run task on the gpu. |

The reason I asked is because I'm getting this on a 1080Ti with 12gb of onboard ram: 1,031.60 1,030.13 10,000.00 Repeating decoration seeds v1 v1.00 (cuda) x86_64-pc-linux-gnu BUT I'm getting this on a 9060XT with 16gb of onboard ram: 613.19 6.17 10,000.00 Repeating decoration seeds v1 v1.03 (opencl_amd) windows_x86_64 or even: 138.10 5.95 10,000.00 Repeating decoration seeds v1 v1.03 (opencl_amd) windows_x86_64 It seems as though my AMD gpu's are not being loaded hardly at all!! Now my 1080Ti is in a Linux pc while both AMD gpu's are in Windows pc's, I don't have any of the reverse right now. |

asking for a friend!! Care to post you app config file for me? |

If you need to run mulitples on your AMD cards to get the utilization up, then just adjust accordingly to get utilization up to above 90%. Here is my app_config.xml you can use as a template.
<app_config>
<app>
<name>loneseed</name>
<gpu_versions>
<gpu_usage>0.5</gpu_usage>
<cpu_usage>0.9</cpu_usage>
</gpu_versions>
</app>
<app>
<name>panopale</name>
<gpu_versions>
<gpu_usage>0.5</gpu_usage>
<cpu_usage>0.9</cpu_usage>
</gpu_versions>
</app>
<app>
<name>repeatdecor</name>
<gpu_versions>
<gpu_usage>0.5</gpu_usage>
<cpu_usage>0.9</cpu_usage>
</gpu_versions>
</app>
</app_config>

Yes that's basically mine. And as always, if you don't know what the name is, just put something in there. The event log will tell you about the names of known applications. |
