That openmp is not functioning is an issue that I will investigate. It should be, so something is wrong. Mostly I find that Sophos is sitting there using 2 cores, and much of my IO.

When preparing the Phenix distribution, Billy Poon has run tests and when Phaser is compiled for Intel and run through Rosetta 2, it’s generally faster than on a recent Intel Mac. However, there have been reports from Phenix users of severe slowdowns, and we don’t understand what the special circumstances are that cause it to slow down on specific jobs. The best performance is when it’s compiled natively for the M1 processor, and I believe both Phenix and CCP4 are aiming to distribute natively-compiled software as soon as technical complications are worked out. So hopefully this is just temporary! I hadn’t realised that the OpenMP wasn’t enabled on CCP4. In Phenix, there were issues preventing the use of OpenMP with Python2, but those should go away when the Python3 version is ready to deploy.
