Yes I know about the curve order being stored in the ellinit structure. Now I added obj_free to the loop but: pari_sp ltop = avma generate random: field, a, b parameters e = ellinit([a,b], field) ellsea(e) ellgenerators(e) random(e) obj_free(e) avma = ltop in a loop, still the memory usage reported goes up after many such loops. ->14.73% (384,000B) 0x518D351: pari_malloc (pariinl.h:1085) | ->14.73% (384,000B) 0x5190097: init_GRHcheck (buch2.c:444) | ->14.73% (384,000B) 0x518A65B: Buchquad (buch1.c:1000) | ->14.73% (384,000B) 0x518B552: quadclassunit0 (buch1.c:1176) | ->14.73% (384,000B) 0x537FF47: classno_wrapper (polclass.c:976) | ->14.73% (384,000B) 0x538262C: polclass0 (polclass.c:1683) | ->14.73% (384,000B) 0x538C2EA: polmodular0_ZM (polmodular.c:2175) | ->14.73% (384,000B) 0x538C7F7: polmodular_ZM (polmodular.c:2237) | | ->14.73% (384,000B) 0x538C846: polmodular_ZXX (polmodular.c:2248) | | ->14.73% (384,000B) 0x51FF45D: get_modular_eqn (ellsea.c:122) | | ->14.73% (384,000B) 0x5207F44: find_trace (ellsea.c:1353) | | ->14.73% (384,000B) 0x520AC08: Fq_ellcard_SEA (ellsea.c:1882) | | ->14.73% (384,000B) 0x520B1CC: Fp_ellcard_SEA (ellsea.c:1951) | | ->14.73% (384,000B) 0x525EA2B: Fp_ellcard (FpE.c:1205) | | ->14.73% (384,000B) 0x51EAAEA: doellcard (elliptic.c:4881) | | ->14.73% (384,000B) 0x547DBFB: obj_checkbuild (init.c:2109) | | ->14.73% (384,000B) 0x51F25B0: ellff_get_card (elliptic.c:6604) or | | | ->09.59% (250,056B) 0x51FF68F: divpol_f2 (ellsea.c:158) | | | | ->03.36% (87,728B) 0x5200A9D: Fq_ellyn (ellsea.c:380) | | | | | ->03.28% (85,408B) 0x5201F4E: Fq_find_eigen_value_power (ellsea.c:629) | | | | | | ->03.28% (85,408B) 0x5202193: find_eigen_value_power (ellsea.c:652) | | | | | | ->03.14% (82,000B) 0x5207627: find_trace_Elkies_power (ellsea.c:1253) | | | | | | | ->03.14% (82,000B) 0x52080BF: find_trace (ellsea.c:1373) | | | | | | | ->03.14% (82,000B) 0x520AC08: Fq_ellcard_SEA (ellsea.c:1882) | | | | | | | ->03.14% (82,000B) 0x520B1CC: Fp_ellcard_SEA (ellsea.c:1951) | | | | | | | ->03.14% (82,000B) 0x525EA2B: Fp_ellcard (FpE.c:1205) | | | | | | | ->03.14% (82,000B) 0x51EAAEA: doellcard (elliptic.c:4881) | | | | | | | ->03.14% (82,000B) 0x547DBFB: obj_checkbuild (init.c:2109) | | | | | | | ->03.14% (82,000B) 0x51F25B0: ellff_get_card (elliptic.c:6604) or | | ->04.28% (111,720B) 0x538365E: cgetg_block (level1.h:147) | | | ->03.89% (101,528B) 0x5388102: zero_block (polmodular.c:975) | | | | ->02.07% (53,872B) 0x538816E: polmodular_db_init (polmodular.c:994) | | | | | ->02.07% (53,872B) 0x538C7CC: polmodular_ZM (polmodular.c:2236) | | | | | ->02.07% (53,872B) 0x538C846: polmodular_ZXX (polmodular.c:2248) | | | | | ->02.07% (53,872B) 0x51FF45D: get_modular_eqn (ellsea.c:122) | | | | | ->02.07% (53,872B) 0x5207F44: find_trace (ellsea.c:1353) | | | | | ->02.07% (53,872B) 0x520AC08: Fq_ellcard_SEA (ellsea.c:1882) | | | | | ->02.07% (53,872B) 0x520B1CC: Fp_ellcard_SEA (ellsea.c:1951) | | | | | ->02.07% (53,872B) 0x525EA2B: Fp_ellcard (FpE.c:1205) | | | | | ->02.07% (53,872B) 0x51EAAEA: doellcard (elliptic.c:4881) | | | | | ->02.07% (53,872B) 0x547DBFB: obj_checkbuild (init.c:2109) | | | | | ->02.07% (53,872B) 0x51F25B0: ellff_get_card (elliptic.c:6604) Cheers, -- Jan ______________________________________________________ /\ # PGP: 362056ADA8F2F4E421565EF87F4A448FE68F329D /__\ # https://neuromancer.sk /\ /\ # Eastern Seaboard Phishing Authority /__\/__\ #
