We present a database of 45,000 atmospheric models (which will become 80,000models by the end of the project) with stellar masses between 9 and 120M$_{\odot}$, covering the region of the OB main sequence and W-R stars in theH-R diagram. The models were calculated using the ABACUS I supercomputer andthe stellar atmosphere code CMFGEN. The parameter space has 6 dimensions: theeffective temperature $T_{\rm eff}$, the luminosity $L$, the metallicity $Z$,and three stellar wind parameters, namely the exponent $\beta$, the terminalvelocity $V_{\infty}$, and the volume filling factor $F_{cl}$. For each model,we also calculate synthetic spectra in the UV (900-2000 Angstroms), optical(3500-7000 Angstroms), and near IR (10000-30000 Angstroms) regions. Tofacilitate comparison with observations, the synthetic spectra wererotationally broaden using ROTIN3, by covering $v$ sin $i$ velocities between10 and 350 km/s with steps of 10 km/s, resulting in a library of 1 575 000synthetic spectra. In order to demonstrate the benefits of employing thedatabases of pre-calculated models, we also present the results of there-analysis of $\epsilon$ Ori by using our grid.
