5) Message boards : Number crunching : Optimize or abandon the VMs? (Message 7148)
Posted 28 Feb 2022 by Profile [VENETO] boboviz
Post:
A volunteer on R@H proposed some VM's optimizations:
- multiattach of virtual disk
- shrink of virtual disk
- change virtual disk controller from IDE to Sata (better perfomances)

Another volunteer proposed to abandon VM using PyInstaller to run app natevely, obviously with better performances and less problems for volunteers.

Both the suggestions are quite easy to implement, so Rosetta@Home will NOT implement these.

Intel released OneApi 2022

Intel created the world’s first unified compiler implementing C++, SYCL and Fortran for CPUs and GPUs utilizing a common LLVM backend.
Accelerated compute on CPUs and GPUs for Python, today’s most popular programming language.
The Intel DPC++ Compatibility Tool was improved to automatically migrate 90% to 95% of CUDA code to SYCL/DPC++

I can run 7 tasks and computer runs, but starting 8th memory comsumption goes over physical memory and swap is being utilized. Swap usage rises to 2gb maximun and Then computer is stalled.


+1
Also my pc with Ryzen is stalled.
I reduced the cpu usage to 20%

Yes. 6Gb of ram per wu is impressive.

It looks interesting - but not enough information to determine if SYCL is BOINC-compatible. Thanks, though.


As i said times ago, boinc is "language agnostic". You can compile and run C++, Cuda, OpenCl, Rocm, R, etc languages without problems.
I remember a project (now closed) with Java app on Boinc.
