Welcome to RASM Latency!
RASML measures the RANDOM AVERAGE SHARED MEMORY LATENCY!

Stored in rasmexename = C:\Source\latency\Release\latency.exe
Trying to allocate 37500000 entries. In total 300000000 bytes
Benchmarking Pseudo Random Number Generator speed, RanRot type 'B'!
Speed depends upon CPU and compile options from RASML,
 therefore we benchmark the RNG
Please wait a few seconds.. ..took 5397 milliseconds to generate  numbers
Speed of RNG = 75894015 numbers a second
So 1 RNG call takes 13.176270 nanoseconds
Benchmarking random RNG test. Please wait..
timetaken=2935
Machine needs 58.700000 ns for RND loop
Trying to Allocate Buffer
Took 0.000 seconds to allocate Hash
Clearing hashtable
Took 0.631 seconds to clear Hash
Starting Other processes
Took 0 milliseconds to start 0 additional processes
Read latency measurement STARTS NOW using steps of 2 * 300.000 seconds :
Raw Average measured read read time at 1 processes = 266.518624 ns
Now for the final calculation it gets compensated:
  Average measured read read time at 1 processes = 207.818615 ns
