The throughput between dom0 & domU seems to be very asymmetry. To my surprise the throughput between domU -> dom0 is more. The value which I specified are consistent values. Is

hi all, I noticed "CONFIG_XEN" appears many times in Xen source code. I''m confused about the meaning of "CONFIG_XEN". For example, in "gnttab.c", the definations of gnttab_map() and gnttab_resume() vary with "ifdef CONFIG_XEN" or not. And I also noticed ifndef CONFIG_XEN , the file <platform-pci.h> is included. So my questions

I have two kind of variables. One kind where the values are continious and ranges from -1 to 5, and the other is boolean (i.e. true or false). For example: V1   V2  V3 V4 V5  V6 0.1  0.4   1    0   -1   3.7 0.4  0.1   2   -1   0    3.7 and V1  V2  V3 0     1    0 0     0    1 I want to make a model for classification, combining this two. Will it be wiser to use the second variable values
