Описание проблемы
Есть небольшой кластер из восьми машин для запуска квантово-химических расчётов. На главной ноде (Ubuntu 12.04) расшарена директория по NFS, на остальных семи (Ubuntu 12.04 Server) она примонтирована с параметром «rw». Ноды в кластере объединены двумя гигабитными сетками (одна для NFS, другая иногда используется для MPI). Входные данные для расчётов читаются из расшаренной директории, результаты и временные файлы пишутся туда же. Пару недель назад появилась проблема: главная нода виснет, если не ошибаюсь, из-за переполнения оперативной памяти. От момента запуска расчётов до «зависания» проходит около 12 часов. Помогите, пожалуйста, определить причину. Буду благодарен любым советам.
На данный момент
На главной ноде занято 1.5 Гб оперативной памяти из 8 Гб, и этот объём продолжает расти.
Load AVG на главной ноде:
6.00 5.98 5.96
Load AVG на остальных:
4.89 4.94 4.95
3.93 3.92 3.93
5.00 4.99 4.95
2.07 1.96 1.84
1.92 1.92 1.99
1.94 1.95 1.95
3.91 3.86 3.82
При этом на главной ноде в htop у всех процессов CPU% по нулям. В нормальном режиме LoadAVG должно быть 0.00 на главной и 4.00 на всех остальных.
