We have conducted a new search for radio pulsars in compact binary systems inthe Parkes multi-beam pulsar survey (PMPS) data, employing novel methods toremove the Doppler modulation from binary motion. This has yielded unparalleledsensitivity to pulsars in compact binaries. The required computation time ofapproximately 17000 CPU core years was provided by the distributed volunteercomputing project Einstein@Home, which has a sustained computing power of about1 PFlop/s. We discovered 24 new pulsars in our search, of which 18 wereisolated pulsars, and six were members of binary systems. Despite the widefilterbank channels and relatively slow sampling time of the PMPS data, wefound pulsars with very large ratios of dispersion measure (DM) to spin period.Among those is PSR J1748-3009, the millisecond pulsar with the highest known DM(approximately 420 pc/cc). We also discovered PSR J1840-0643, which is in abinary system with an orbital period of 937 days, the fourth largest known. Thenew pulsar J1750-2536 likely belongs to the rare class of intermediate-massbinary pulsars. Three of the isolated pulsars show long-term nulling orintermittency in their emission, further increasing this growing family. Ourdiscoveries demonstrate the value of distributed volunteer computing fordata-driven astronomy and the importance of applying new analysis methods toextensively searched data.
