s is the speed in MHz.
+As an alternative to the above, one can set NumPhysicalCores=n in local.txt.
+This is useful on machines that are somtimes booted with hyperthreading enabled

+hyperthreading state properly no matter how the machine is booted.

+New features in Version 26.6 of mprime
+--------------------------------------
+
+1) For rare cases where the program cannot figure out the number of cores and hyperthreading,
+ the NumPhysicalCores option may help. See undoc.txt.
+2) Faster FFT implementations are now selected for Core 2 CPUs with 1MB L2 cache or less
+ (marketed under the Celeron and Pentium label).
+3) New, slightly higher, trial factoring breakeven points.
