Probing the baryons in the intergalactic medium (IGM) through the Lyman alpha forest, the Sunyaev-Zeldovich effect, and the X-ray background is the next important task in cosmology. The evolution of the intergalactic medium is a numerically challenging problem to solve but advancements in hydrodynamic codes and computational techniques now make it tractable to simulate the IGM for the purpose of doing quantitative cosmology. We describe an out-of-core computing paradigm for very high-resolution simulations and a new code designed to handle the high Mach number dynamic range of the IGM. Out-of-core computation refers to the technique of using disk space as virtual memory and transferring data in and out of main memory at high I/O bandwidth. We present some results on the baryon budget and thermodynamic scaling relations from cosmological simulations with 20003 grid cells and 10003 dark matter particles.
