Re: ABINIT 8.8.1 is much slower than ABINIT 8.6.3 ???

Thanks Eric. I have reinstall my virtual machine with the newest CentOS-1804 and re-compiling my ABINIT-8.6.3 and ABINIT-8.8.1 under Windows 10 system. This time, I don't use the shared folder. All files are within the virtual machine. With the same input file, the ABINIT 8.6.3 takes 6'26'', but the...

ABINIT 8.8.1 is much slower than ABINIT 8.6.3 ???

Hello everyone: I find a strange phenomenon: With the same compiling parameters, the abinit 8.8.1 is much slower than abinit 8.6.3. e.g for Al with vacumn slabs, the abinit 8.6.3 is about ~6 min, but the abinit 8.8.1 needs near 30+ min. Why? PS: virtual machine, 4 cores, 8 GB, CentOS 7.3 with openmp...
