Update compute-nodes.md PROOFREAD 

line 13; [and throughout] be aware that british English uses . as a decimal place i.e. 2.5 = 5/2. So does the US, however, more countries overall use , as the decimal place. So either is fine, but it should be consistent - line 13 uses . for example.
line 94; I'm not sure what you mean by 'all nodes of job'
