These NOELIA_c36x467x workunits use much more CPU computation (double precision FP) than the GERARD tasks, but they are not faster on Windows 10 than on Windows XP. (however the total WDDM overhead is much less for these tasks)
My Windows XPx64 + i7-4790K + GTX 980Ti + DDR3 1866MHz host can finish these in 18967~19372 seconds (5h 16m 7s - 5h 22m 52s).
GERARD_VACXCL12_LIG: 20583~20808 seconds on the same host.
But I have an experimental host:
Windows XPx64, Core2 Duo E8500 (3.16GHz), DQ45CB motherboard, 2x2GB DDR2 800MHz RAM, GTX 980Ti (ASUS Strix).
This host can finish a NOELIA_c36x467x in 25504~25583 seconds.
The runtime increase of the NOELIA_c36x467x workunits on the experimental host is nearly 6 times higher than of the GERARD_VACXCL12_LIG, so it's the CPU architecture and the other tasks running limits the performance of the NOELIA_c36x467x tasks (besides the OS and the WU itself).
