This was the telescope that Edwin Hubble, for whom the Hubble Space Telescope was named, used to demonstrate that the universe is expanding. For nearly four decades, the 100-inch telescope was the largest in the world after its commissioning in 1917. In 1985 the telescope was mothballed due to a lack of funding. Recently, however, the telescope was refurbished and recommissioned. As I made my way to the telescope control room, I wondered what it was going to be like to use the old giant.
Old telescopes are generally very finicky and all have their own personalities.
But when I went into the control room, I was greeted by a very familiar sight. But OS2's preemptive multitasking and multithreading capabilities make it a powerful contender when considering operating systems for a PC workstation. The work involved running my hydrodynamics code and then comparing the results to observations of these stars. It would usually take several days for one simulation to run to completion. Naturally, I wanted to be able to use the PC for other things while the hydro simulations were running.
